APXE100ARA271MH70G - 270µF 10V Polymer Aluminum SMD Capacitor | Nippon Chemi-Con
The Nippon Chemi-Con APXE100ARA271MH70G is a conductive polymer aluminum solid capacitor rated at 270µF / 10V in an 8×6.7mm radial-can SMD package, designed to deliver ultra-low ESR (21mΩ typical) and high ripple current handling (3220mArms at 100kHz / 105°C). As a member of the APXE series, it uses a conductive polymer electrolyte instead of liquid, which is the foundation of its low-impedance performance and 15000-hour endurance rating at 105°C. A polymer aluminum capacitor is a polarized aluminum electrolytic capacitor whose cathode is a conductive polymer layer rather than a liquid electrolyte. This construction places it in the broader taxonomy of electrolytic capacitor -> aluminum capacitor -> aluminum polymer capacitor -> surface-mount aluminum polymer capacitor. The polymer cathode eliminates the wet-electrolyte failure modes that limit conventional aluminum electrolytics, yielding lower ESR, benign failure behavior, and longer life at high temperatures. Key performance attributes include a typical ESR of 21mΩ at 100kHz, ripple current capability of 3220mArms at 105°C with 100kHz forced-air conditions, 2000-hour load-life rating (with the APXE series offering 15000 hours at 105°C for smaller-case variants), a 6.7mm can height, and ±20% capacitance tolerance at 20°C/120Hz. The 8×6.7mm SMD form factor lands on a typical 8.30×8.30mm or 10.30×10.30mm PCB land pattern, making it drop-in compatible with several industry-standard radial-can SMD polymer aluminum footprints. Typical applications include output filtering and decoupling in DC-DC point-of-load converters, bulk hold-up capacitors for graphics and server processors, low-voltage rails in telecom base-station equipment, and any PCB location where low-ESR bulk capacitance is required at the smallest possible can size. The 3220mArms rating lets the device absorb the high-frequency ripple produced by switching regulators without overheating, preserving system efficiency and long-term reliability. When designing with this part, derate the applied voltage to remain below the 10V rated maximum, keep the surface temperature under the published 105°C category, and ensure the PCB land pattern matches the can diameter (8mm) so the part self-aligns during reflow. This page consolidates distributor pricing, drop-in alternatives, and design considerations that supplement the manufacturer datasheet.
C0402C224M9PACTU - 0.22uF 6.3V X5R 0402 MLCC | KEMET
The KEMET C0402C224M9PACTU is a 0.22 uF, 6.3 V rated multilayer ceramic capacitor (MLCC) in a 0402 (1005 Metric) surface-mount package, using the X5R dielectric. It carries a +/-20% capacitance tolerance, an operating temperature range from -55C to +85C, and is supplied on 180 mm paper tape-and-reel packaging. The 0402 land pattern makes it suitable for high-density PCB designs where decoupling, bypass, or general filtering is required on 3.3 V and lower supply rails. A multilayer ceramic capacitor (MLCC) is a passive surface-mount component consisting of alternating layers of ceramic dielectric and metal electrodes fired into a monolithic block. The X5R dielectric is a Class II (mid-K) formulation that offers higher capacitance per volume than Class I (C0G/NP0) dielectrics, at the cost of greater capacitance change with temperature, DC bias, and aging. X5R parts are typically specified for -55C to +85C with +/-15% maximum capacitance variation across that range. This places X5R firmly in the decoupling, bypass, and general-purpose filtering role rather than precision timing or filter applications. Key features include 0.22 uF nominal capacitance in a 0402 footprint, 6.3 V DC rated voltage, +/-20% tolerance, X5R temperature characteristic (EIA code 2), and a lead-free (Sn) matte tin termination that is RoHS compliant. The part uses KEMET's commercial-grade SMD Comm X5R series and is qualified to 85C continuous operation. KEMET's Flex Termination option (the FT suffix found on similar parts) is NOT present on this -TU variant, which uses a standard tin termination suitable for reflow soldering on standard ENIG or tin-pad surfaces. The C0402C224M9PACTU is most commonly used to decouple low-voltage digital ICs such as microcontrollers, FPGAs, ASICs, and DSPs that operate from 1.8 V, 2.5 V, 3.3 V, or 5 V rails. With 0.22 uF of bulk storage in a 0402 footprint, it complements 0.1 uF and 1 nF capacitors that handle higher-frequency noise, while its small size preserves routing channels in dense BGA and QFN layouts. X5R parts exhibit significant DC-bias derating; at 5 V applied the actual capacitance may be 30-50% lower than the nominal 0.22 uF, which should be considered when sizing hold-up time or filter cutoffs. Typical applications include microcontroller bypass on 3.3 V rails, decoupling for low-power wireless SoCs, bulk filtering on USB data lines, and general-purpose coupling capacitors in audio and signal-chain PCBs. The 0402 size supports hand-rework and visual inspection in prototypes while still being compatible with high-volume pick-and-place assembly. When designing with this part, account for X5R DC-bias derating: at the rated 6.3 V the real capacitance can drop substantially versus the 0.22 uF nominal, so verify effective capacitance with KEMET's K-SIM tool or the manufacturer SPICE model. Place the capacitor as close to the IC power pin as possible, and pair it with a smaller 0.01 uF or 0.1 uF cap to cover high-frequency noise that X5R cannot effectively suppress above its self-resonance.

C0603C104K5RACTU - 0.1uF 50V X7R 0603 MLCC | KEMET
The KEMET C0603C104K5RACTU is a 0.1 uF (100 nF) multilayer ceramic capacitor (MLCC) with a 50 V DC rating, plus/minus 10% tolerance, X7R temperature-stable dielectric, and an 0603 (1608 metric) surface-mount package in the C-Series commercial offering. A multilayer ceramic capacitor is a passive component built by stacking alternate layers of ceramic dielectric and metal electrodes, then sintering the structure into a monolithic chip. Within the passive component hierarchy, MLCCs belong to the capacitor family alongside film, tantalum, and aluminum electrolytic types, and are the dominant decoupling and bypass technology in modern surface-mount electronics due to their small size, low ESR, and non-polarized operation. Key features of the C0603C104K5RACTU include the X7R Class II dielectric, which maintains capacitance within plus/minus 15% across the -55C to +125C temperature range, a 50 V DC working voltage suitable for most logic rails, and matte-tin-plated nickel-barrier terminations that provide excellent solderability for reflow and wave soldering processes. The X7R dielectric is considered temperature stable by KEMET, with a maximum operating temperature of 125C. Like all Class II dielectrics, capacitance varies with applied DC bias and aging; engineers should consult the manufacturer datasheet DC bias curves when the effective capacitance under bias is critical to the design. The non-polarized construction means there are no orientation constraints during PCB assembly. Typical applications, per the manufacturer datasheet, include decoupling, bypass, filtering, and transient voltage suppression. The 0.1 uF/50 V combination is the classic logic-IC decoupling value, placed close to VCC pins of microcontrollers, FPGAs, and digital ICs, and is equally common in analog signal-chain filtering. Design consideration: for 5 V and 3.3 V rails, the 50 V rating provides generous margin, but at the maximum 125C ambient the effective capacitance can drop; verify derating requirements early. This page synthesizes distributor pricing, drop-in alternates, and practical design notes not found in the manufacturer datasheet.
C0603X472F5GACAUTO - 4.7nF 50V C0G 0603 Automotive MLCC | KEMET
The KEMET C0603X472F5GACAUTO is an automotive-grade surface-mount multilayer ceramic capacitor (MLCC) with a capacitance of 4700 pF (4.7 nF) and a ±1% tolerance, rated at 50 V DC, built on a C0G/NP0 dielectric platform and housed in a 0603 (1608 metric) Flex Termination (FT-CAP) package. As part of the KEMET SMD Auto C0G Flex series, it is qualified to the AEC-Q200 automotive stress test standard and is designed for high-reliability analog signal chains where capacitance stability with temperature, voltage, and age is critical. A C0G (also written NP0) dielectric is a Class I ceramic formulation characterised by essentially zero capacitance change over its operating temperature range, zero DC bias dependence, and negligible aging. Class I MLCCs sit at the top of the MLCC hierarchy (MLCC -> ceramic capacitor -> passive component -> electronic component), chosen wherever the application demands precision rather than volumetric efficiency, in contrast to Class II/III dielectrics such as X7R, X5R, or Y5V which trade stability for higher capacitance per unit volume. Key specifications include 50 V rated voltage, 4.7 nF nominal capacitance, ±1% tight tolerance, C0G temperature coefficient (0 ±30 ppm/°C from -55°C to +125°C), and the FT-CAP flexible termination system that mitigates mechanical stress and flex-cracking during PCB assembly, thermal cycling, and automotive under-hood vibration. The 0603 footprint measures 1.6 mm × 0.8 mm × 0.8 mm with a 0.58 mm minimum solder gap. The FT-CAP flexible termination uses a silver-loaded epoxy layer between the nickel barrier and the tin solder finish, absorbing substrate flexure stress that would otherwise crack standard BME terminations. This construction is particularly relevant for large-panel automotive PCB assemblies and MLCCs positioned near board edges, screw holes, or connector stress points. Typical applications include ADAS sensor signal conditioning, automotive infotainment audio filters, engine ECU analog front-end filtering, EV battery management analog rails, and industrial high-precision filtering. Designers select this part when a 4.7 nF C0G capacitor is required in a 0603 footprint with AEC-Q200 qualification and FT-CAP stress tolerance. When designing with this component, observe the standard 0603 land pattern recommendations from KEMET's IPC-7351 compliant footprint and avoid placing the device in high-mechanical-stress zones without additional strain relief. For non-automotive designs where C0G stability is required but AEC-Q200 is unnecessary, the KEMET C0603C472F5GACTU (commercial grade) offers identical electrical performance in the same 0603 package. This page synthesises distributor pricing, drop-in KEMET same-family and competitor cross-brand alternatives, and practical PCB layout guidance not found in the standalone KEMET datasheet, giving engineers a single reference for sourcing and second-source qualification.
C0805C106K8RACTU - 10uF 10V X7R 0805 MLCC | KEMET
The KEMET C0805C106K8RACTU is a 10 uF multilayer ceramic capacitor (MLCC) rated at 10 V DC with an X7R dielectric, a tolerance of plus or minus 10 percent, housed in a surface-mount 0805 (2012 Metric) chip package from the KEMET C Series. An MLCC is the most widely used capacitor type in modern electronics: alternating layers of ceramic dielectric (here barium-titanate-based Class 2 X7R material) and nickel or precious-metal electrodes are co-fired into a monolithic block, terminated on opposing ends for surface mounting. Within the component hierarchy, the MLCC sits under fixed capacitor, under capacitor, and under passive electronic components. Class 2 dielectrics such as X7R offer high volumetric efficiency at the cost of some capacitance variation with voltage, temperature, and time, in exchange for compact decoupling-grade capacitance. Key features of this part include 10 uF of capacitance in a compact 2.0 mm x 1.25 mm footprint, an X7R temperature characteristic stable from -55 degrees C to +125 degrees C with a maximum capacitance change of plus or minus 15 percent across that range, and tight plus or minus 10 percent initial tolerance. The C Series construction supports reflow soldering and standard SMT pick-and-place assembly. Typical applications documented by KEMET include decoupling, bypass, filtering, and transient voltage suppression. Technically, the X7R dielectric provides high dielectric constant (high k), enabling Class 2 MLCCs to reach 10 uF in 0805 without stacking to larger case sizes. Like all X7R parts, its effective capacitance decreases under DC bias, so designers should derate the working voltage relative to the 10 V rating for bias-sensitive circuits such as timing networks; bulk decoupling duties are far more tolerant of this behavior. Typical use cases include power-rail decoupling for microcontrollers and FPGAs, bypass of analog supply pins on op-amps and data converters, low-pass filter networks in power supplies, and transient voltage suppression at connector entry points in industrial and consumer equipment. A key design consideration: place this capacitor close to the decoupled IC power pin and account for DC bias derating - at high bias fractions of the 10 V rating, delivered capacitance can fall well below the nominal 10 uF, so verify the effective value with the manufacturer DC bias curves in the KEMET datasheet. This page adds value beyond the raw datasheet by synthesizing distributor pricing from DigiKey, Mouser, and LCSC, same-package drop-in alternatives, and practical design notes for bias derating and layout.
C1608X5R105KDTS - 1µF 10V X5R MLCC 0603 10% | Darfon
The Darfon C1608X5R105KDTS is a 1 µF (1000000 pF) ceramic chip capacitor in an 0603 (1608 metric) surface-mount package, rated for 10 V DC and characterized with the X5R temperature coefficient (EIA Class 2 mid-stability dielectric). It carries a ±10% capacitance tolerance and operates over a temperature range with a maximum operating temperature of +85 °C, satisfying the X5R -55 °C to +85 °C window with ±15% capacitance change across the rated range. The component is supplied on 7-inch Tape & Reel and is qualified to a maximum dissipation factor of 7.50% measured at 1 kHz / 1 V RMS. An MLCC (multi-layer ceramic capacitor) is a passive component built by stacking many thin dielectric layers and internal metal electrodes into a monolithic body. X5R is an EIA Class 2 dielectric, meaning it provides much higher volumetric capacitance than Class 1 (NP0/C0G) ceramics but with a capacitance value that changes with temperature, DC bias, and aging. Compared with tantalum and aluminum electrolytic capacitors, X5R MLCCs offer lower ESR, lower leakage, no polarity, and superior high-frequency behavior, which is why they dominate decoupling, bypass, and filtering roles on modern densely populated PCBs. Key features of this part include the 0603 (1608) footprint - the industry workhorse case size for general-purpose decoupling - a 10 V rating that provides 2× derating margin against the typical 3.3 V or 5 V rails it will sit on, and a ±10% (K) tolerance suitable for bulk bypass applications where tight tolerance is unnecessary. The DF max of 7.50% at 1 kHz/1 V is consistent with a 1 µF X5R 0603 part at this voltage rating, and is acceptable for decoupling, filtering, and general energy-storage roles. This part is not qualified to AEC-Q200 and is therefore intended for commercial / industrial / consumer use rather than under-hood automotive environments. Typical applications include digital IC decoupling on 3.3 V and 5 V logic rails, bulk filtering at power-rail outputs of small buck regulators, audio signal-chain coupling and bypass, USB and low-speed data-line RC filtering, and general-purpose timing and RC networks. Designers commonly place several 1 µF X5R 0603 capacitors near each power pin of microcontrollers, FPGAs, and transceivers to provide local charge reservoir and high-frequency bypass. When designing with this part, observe the DC-bias derating behavior typical of X5R 1 µF 0603 parts - effective capacitance can drop 20-40% near full rated voltage, so consider 2.2 µF or 4.7 µF parts at higher voltages if the in-application capacitance is critical. Always confirm the actual capacitance under the worst-case VIN bias and lowest operating temperature.
CL05A106MP5NUNC - 10µF 10V X5R 0402 MLCC | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL05A106MP5NUNC is a 10 µF ±20% 10V X5R multilayer ceramic capacitor (MLCC) in a 0402 (1005 metric) surface-mount package. The device is built using Samsung's advanced multilayer ceramic technology with X5R temperature characteristic, providing stable capacitance across -55 °C to +85 °C and excellent volumetric efficiency at 0402 dimensions. An MLCC (Multilayer Layer Ceramic Capacitor) is a passive component constructed by alternating layers of ceramic dielectric and metal electrodes, then sintered into a monolithic block. X5R is a Class 2 dielectric defined by EIA-198, offering moderate volumetric efficiency with capacitance change typically within ±15% over its rated temperature range. In the broader taxonomy, MLCCs sit under ceramic capacitors, which fall under capacitors, which fall under passive components. MLCCs dominate decoupling, bypass, and energy-storage applications in modern electronics because of their low ESR, low ESL, small footprint, and ability to be placed directly under IC power pins. Key features of the CL05A106MP5NUNC include 10 µF nominal capacitance, ±20% tolerance, 10 V rated voltage, X5R dielectric, and a 0402 footprint (1.0 × 0.5 mm). The device is supplied in tape-and-reel packaging suitable for high-speed automated assembly. Per the manufacturer datasheet, the cap exhibits typical ESR well below 100 mΩ at 1 kHz, making it highly effective for high-frequency decoupling. The X5R temperature profile trades wide temperature stability for higher capacitance density compared to C0G/NP0 parts. Typical applications include bulk decoupling of IC power rails, smartphone PMIC output filtering, IoT module bypass, and battery management bypass networks. The compact 0402 footprint supports high-density PCB layouts where board real estate is at a premium, particularly under SoCs and microcontrollers. Design engineers commonly select this part as a 1-3 piece-per-rail bypass capacitor paired with smaller 0.1 µF values. When designing with X5R MLCCs, engineers must apply DC bias derating: a 10 µF 0402 X5R part may lose 60-80% of its nominal capacitance at 5 V DC bias. Always verify effective capacitance under operating voltage, not just nominal 1 Vrms capacitance. For designs requiring tight tolerance or low-loss RF coupling, C0G/NP0 dielectrics should be considered instead. This page synthesizes distributor pricing, drop-in alternatives, and DC-bias-aware design notes not consolidated in any single manufacturer datasheet, supporting faster sourcing decisions for compact decoupling applications.
CL05A226MQ5QUNC - 22µF 6.3V X5R MLCC 0402 | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL05A226MQ5QUNC is a 22 µF ±20% 6.3V X5R multilayer ceramic capacitor (MLCC) in a 0402 (1005 metric) surface-mount package. It delivers 22 µF nominal capacitance at 6.3V rated voltage using a Class-2 X5R dielectric, which is engineered to retain between -55 °C and +85 °C with a ΔC of ±15% relative to the 25 °C reference. The 0402 footprint (1.0 mm × 0.5 mm) makes it one of the highest-capacitance-per-area parts in the Samsung CL series and a popular choice for portable and wearable designs where PCB real estate is constrained. An MLCC (multilayer ceramic capacitor) is a passive surface-mount component constructed by stacking alternating metal-electrode and ceramic-dielectric layers in a single monolithic body, then sintering and terminating the stack with nickel-barrier solder lands. The X5R dielectric is a Class-2 (mid-stability) formulation balancing volumetric efficiency against temperature and DC-bias performance; X5R sits in the ceramic capacitor family hierarchy MLCC > ceramic capacitor > capacitor > passive component, and is the standard choice for general-purpose decoupling, bulk bypass, and filtering in 5V-or-less rails. Key features of the CL05A226MQ5QUNC include a 22 µF capacitance in the smallest common SMD case (0402), a ±20% capacitance tolerance, X5R temperature characteristic (EIA standard), nickel-barrier solder terminations with matte-tin plating for excellent solderability, and compliance with RoHS3. The terminations support reflow soldering up to 260 °C peak and the device is rated MSL 1 (unlimited floor life). According to the manufacturer datasheet, designers should evaluate capacitance behavior in the actual system because X5R capacitance varies with applied DC voltage (DC bias) and temperature. Typical applications include bulk decoupling of low-voltage IC rails (PMIC, SoC core supplies), bypass on portable/wearable electronics, smoothing on audio codec supplies, and general-purpose filtering on 3.3V and 5V power domains. Designers using this part should derate for DC-bias losses (effective capacitance drops as DC voltage approaches rated voltage) and verify in-system ripple current. The Samsung CL series shares identical land patterns across the family, allowing flexibility to step down to 10 µF or up to 47 µF in the same 0402 footprint when the BOM or sourcing requires it.
CL05B102KB5NNNC - 1nF 50V X7R 0402 MLCC | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL05B102KB5NNNC is a 1 nF (1000 pF) ±10% 50 V X7R multilayer ceramic chip capacitor (MLCC) in the industry-standard 0402 (1005 Metric) footprint. Housed in a 1.00 mm x 0.50 mm surface-mount land pattern, it is supplied on paper carrier tape (7-inch reel) with a nickel-barrier and tin (Sn) plated termination suitable for reflow soldering. A multilayer ceramic capacitor (MLCC) is a passive surface-mount component formed by stacking alternating layers of nickel inner electrodes and a ceramic dielectric. The X7R dielectric classification (per EIA-198) means -55°C to +125°C operating range with ±15% capacitance variation across that band. Compared to C0G/NP0 (Class I) parts, X7R offers substantially higher volumetric efficiency (more capacitance per mm3) at the cost of higher temperature coefficient and lower Q. MLCCs sit below supercapacitors, aluminum electrolytics, and film capacitors in the passive-component hierarchy and are the workhorse decoupling and bypass device in modern digital electronics. Key specifications include 1000 pF nominal capacitance, ±10% tolerance (K code), 50 V DC rated working voltage, X7R temperature characteristic, and a 0402 case size (1.00 x 0.50 x 0.50 mm). The termination finish is nickel-barrier with matte-tin plating for excellent solderability and resistance to leaching during reflow. The device is qualified to Samsung's standard reliability test program including temperature cycling, bias humidity, and thermal shock, and is supplied in compliance with RoHS, REACH, and halogen-free directives. Electrically, the X7R dielectric delivers moderate-to-high volumetric efficiency and reasonably stable performance in audio coupling, decoupling, and filter networks. At 1 nF the part sits in a useful mid-range capacitance window: large enough for general IC decoupling on sub-100 MHz digital rails, small enough for analog filter sections and high-frequency bypass duty. Equivalent series resistance (ESR) is low and self-resonant frequency is well above 100 MHz, supporting broadband noise suppression. Typical applications include high-frequency decoupling of microcontrollers (PIC32MZ, STM32, Kinetis), DC blocking in audio line-level signal paths, RC time-constant networks in oscillators and timers, EMI/RFI bypass on analog sensor lines, and general-purpose bypass capacitors on low-voltage (3.3 V / 5 V) power rails. Designers routinely select 1 nF 0402 X7R capacitors for tight PCB layouts where 0201 pad geometry is impractical and where C0G stability is not required. When designing with the CL05B102KB5NNNC, observe the 50-V working voltage derating guideline of roughly 50% in high-reliability applications (target 25 V or below for long-term reliability). Place the device within 2-3 mm of the IC supply pin and use wide, short traces to minimize parasitic inductance. For noise-sensitive analog circuits, prefer C0G/NP0 alternatives; for high-density digital decoupling, parallel multiple 100 nF and 1 nF X7R parts for broadband supply noise suppression. This page synthesizes distributor pricing tiers, drop-in alternatives from both Samsung and competitor manufacturers, and practical PCB layout guidance not found in the manufacturer datasheet alone.
CL10A106KP8NNNC - 10uF 10V X5R 0603 MLCC | Samsung
The Samsung Electro-Mechanics CL10A106KP8NNNC is a 10 uF multilayer ceramic capacitor (MLCC) with a 10 V DC rating, X5R dielectric, and +/-10% tolerance, housed in a 0603 (1608 metric) surface-mount package. An MLCC is a passive component built from alternating layers of ceramic dielectric and metal electrodes, terminated at opposite ends for surface mounting. Within the passive component hierarchy (capacitor -> ceramic capacitor -> multilayer ceramic capacitor -> SMD passives), MLCCs are the workhorse decoupling and filtering elements of modern electronics, valued for small size, low ESR, and high reliability compared with tantalum or aluminum electrolytic alternatives. Key features of this part include 10 uF of capacitance in a compact 1.6 x 0.8 mm footprint, X5R temperature characteristic (-55C to +85C with up to +/-15% capacitance change), a 10 V rated voltage, and K-code +/-10% tolerance. Nickel-barrier and tin-plated terminations ensure compatibility with reflow soldering and support RoHS-compliant lead-free assembly. Technically, the X5R Class II dielectric provides high volumetric efficiency - achieving 10 uF in 0603 was a benchmark when this part was introduced. Engineers must account for DC bias derating and aging: effective capacitance under bias can fall substantially from the nominal 10 uF, and Class II dielectrics age over time, so designs should verify bias curves in the Samsung datasheet. Typical applications include power-rail decoupling for FPGAs and microcontrollers, point-of-load DC-DC converter output filtering, control-plane support networks, storage and networking modules, and compact high-speed embedded hardware where board area is at a premium. A key design consideration: X5R capacitance drops with applied DC voltage and temperature. If a rail needs guaranteed minimum capacitance at 85C under bias, verify the effective capacitance rather than nominal, or select a larger case size or higher voltage rating. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
CL10B105KA8NNNC - 1uF 25V X7R 0603 MLCC | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL10B105KA8NNNC is a 1 microfarad (1 uF) X7R multilayer ceramic capacitor (MLCC) rated at 25 VDC, supplied in an industry-standard 0603 (1608 metric) surface-mount package. Built with a +/-10% capacitance tolerance and a Class II X7R dielectric, the part delivers stable performance across -55C to +125C operating temperatures and is designed for general-purpose decoupling, filtering, and bypass applications in commercial electronics. A multilayer ceramic capacitor (MLCC) is a passive surface-mount component formed by stacking alternating layers of ceramic dielectric and metal electrodes, then sintering the stack into a monolithic block with metal terminations on both ends. MLCCs sit within the broader passive component hierarchy: capacitor -> ceramic capacitor -> MLCC -> Class II (X7R/X5R) dielectric family. Class II dielectrics such as X7R use high-permittivity barium-titanate-based ceramics to achieve capacitance values many times larger per unit area than Class I (C0G/NP0) types, at the cost of greater capacitance change with temperature, voltage, and age. Key specifications include 1 uF nominal capacitance at 25 VDC rated voltage, +/-10% tolerance, X7R temperature characteristic (EIA code: X7R = +/-15% delta-C over -55C to +125C), 0603 (1608 metric) case size, and tape-and-reel packaging on a 7-inch reel per EIA-481. The 0603 footprint measures 1.60 mm x 0.80 mm (L x W) with a nominal 0.80 mm height, making the device compatible with standard pick-and-place and reflow processes. The terminations are nickel-barrier with tin (Sn) plating for lead-free reflow soldering. Architecturally, the device uses Samsung's fine-grained X7R dielectric formulation with internal electrode layers screened to achieve the 1 uF rating within the compact 0603 case. X7R parts exhibit capacitance loss with applied DC bias (DC-bias effect), so the effective capacitance at the rated 25 V is typically 30-50% of the nominal 1 uF value - a key consideration in low-impedance decoupling designs where full 1 uF is assumed. Typical applications include power-rail decoupling on microcontrollers, FPGAs, and ASICs, local filtering around voltage regulators, AC-coupling and DC-blocking in audio and signal-chain paths, and general-purpose bypass on data lines. The 25 V rating comfortably covers 3.3 V, 5 V, and 12 V rails while leaving margin for transients. When designing with this part, verify effective capacitance under DC bias using the manufacturer's bias curve, and provide adequate copper land-pad area to absorb thermal and mechanical stress during reflow. Avoid placing the capacitor directly under flex zones or near PCB edges subject to high strain.

CL10B106MQ8NRNC - 10uF 6.3V X7R 0603 MLCC | Samsung Electro-Mechanics
Samsung Electro-Mechanics CL10B106MQ8NRNC is a 10 uF +/-20% 6.3V X7R multilayer ceramic capacitor (MLCC) in a 0603 (1608 metric) surface-mount package, supplied on 7-inch tape and reel. According to distributor listings, it measures 1.60 mm x 0.80 mm with a 0.90 mm maximum thickness, making it suitable for high-density PCB assemblies where board real estate is at a premium. The X7R dielectric provides stable performance over -55C to +125C with a +/-15% capacitance variation across the operating temperature range, a common compromise between the high-stability C0G/NP0 dielectric and the high-capacitance-per-volume Y5V class. What is an MLCC? A multilayer ceramic capacitor is a surface-mount passive component built by stacking alternating layers of metal electrodes and a ceramic dielectric body, then sintering and terminating the structure with nickel-barrier and tin solder end-caps. MLCCs sit in the hierarchy of passive components -> capacitors -> ceramic capacitors, and within that branch they are the dominant technology for general-purpose decoupling, filtering, and bypass functions on modern digital and analog boards. Key features of the CL10B106MQ8NRNC include the industry-standard 0603 EIA footprint, 6.3V rated DC working voltage (well above the typical 3.3V or 5V rails where it is most often deployed), and +/-20% capacitance tolerance that is acceptable for bulk decoupling. The X7R dielectric delivers reasonable volumetric efficiency at 10 uF in 0603, a capacitance that historically would have required a much larger case such as 1210. The X7R temperature characteristic trades off against C0G's near-zero temperature coefficient for a substantially higher capacitance-per-volume. Typical applications for the CL10B106MQ8NRNC include bulk decoupling of 3.3V and 5V digital IC rails, local bypass on microcontroller power pins, smoothing on low-dropout (LDO) regulator outputs, and energy storage for short power-rail transients on portable and IoT devices. The 6.3V rating gives designers comfortable margin on 3.3V rails and acceptable margin on 5V rails where DC plus AC ripple stays below the rated voltage. When laying out the 0603 land pattern, follow IPC-7351 nominal pads (roughly 0.9 mm x 0.8 mm) and avoid placing the part directly under tall components that could trap solder during reflow.

CL10B475KQ8NQNC - 4.7µF 6.3V X7R 0603 MLCC | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL10B475KQ8NQNC is a 4.7 µF ±10% multilayer ceramic capacitor (MLCC) rated at 6.3 V DC in an X7R dielectric, packaged in the industry-standard 0603 (1608 metric) case size measuring 1.60 × 0.80 mm. According to the manufacturer specification sheet (issued AUG.27.2025), this part uses Samsung's CL series general-purpose MLCC line with nickel-barrier + tin (Ni/Sn) terminations suitable for reflow soldering. A ceramic capacitor is a passive two-terminal component that stores energy in an electric field formed by alternating layers of metal electrodes and a ceramic dielectric. The X7R dielectric is a 'stable' Class II formulation defined by EIA-198: capacitance variation of ±15% across the operating temperature range of −55 °C to +125 °C, with a maximum dissipation factor of 10% at 1 kHz/1 Vrms. Within the broader taxonomy, this device is a chip capacitor → MLCC → ceramic capacitor → capacitor → passive component. Sibling dielectrics include X5R (smaller temperature range, higher capacitance per volume) and C0G/NP0 (zero TC, lower capacitance density). X7R is the most common general-purpose choice for decoupling and bulk filtering in digital, analog, and power circuits. Key features include 4.7 µF nominal capacitance in the compact 0603 footprint (unusually high capacitance density for this case size), ±10% capacitance tolerance (K code per EIA), 6.3 V rated DC working voltage, X7R temperature characteristic (±15% from −55 °C to +125 °C), and a paper + embossed plastic tape packaging format. The Ni-barrier tin finish supports lead-free reflow profiles up to 260 °C peak (per JEDEC J-STD-020). Because this part is a 2-terminal passive, there is no polarity, no enable pin, and no SOA curve. From a technical-depth perspective, the X7R dielectric delivers high volumetric efficiency (typically 1–10 µF in 0603) at the cost of some voltage coefficient and aging. The 6.3 V rating provides minimal margin above common 3.3 V and 5 V rails — derate to ≤80% of rated voltage for long-term reliability when used near maximum temperature. The 0603 footprint is reflow-solder compatible and compatible with both Pb-free and SnPb profiles, making the part broadly drop-in across consumer, industrial, and telecom assemblies. Typical applications include IC decoupling on 3.3 V / 5 V digital rails (microcontrollers, FPGAs, ASICs), bulk hold-up on low-voltage power rails, filter capacitor in audio and sensor signal chains, and bypass capacitor near DC-DC converter inputs. The 4.7 µF value is the workhorse bulk level for point-of-load decoupling of moderate-current digital devices. When designing with this part, place the capacitor as close as possible to the IC supply pin to minimize parasitic inductance, and pair with a smaller 0.1 µF high-frequency bypass cap on the same rail for broadband decoupling. Be aware that X7R loses 30–60% of nominal capacitance under DC bias — verify effective capacitance at the working voltage, not at the 0-V small-signal spec.

CL10C180JB8NNNC - 18pF 50V C0G 0603 MLCC | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL10C180JB8NNNC is a 18 pF ±5% 50 V multilayer ceramic capacitor (MLCC) in the C0G (NP0) dielectric class, supplied in a 0603 (1608 metric) surface-mount package. It is rated for 18 pF nominal capacitance, ±5% tolerance, and 50 V DC working voltage, with the C0G/NP0 dielectric providing the lowest capacitance change versus temperature in the EIA-198 Class I family. According to the Samsung EM MLCC datasheet (general MLCC catalog), the device is supplied in 7-inch paper tape on reel for high-speed automated assembly. Background knowledge: a Class I MLCC (C0G/NP0) is a ceramic capacitor whose dielectric is a non-ferroelectric, temperature-compensating formulation. C0G is defined by the EIA-198 standard and exhibits a temperature coefficient of 0 ±30 ppm/°C across -55 °C to +125 °C, with no aging of capacitance over time and essentially zero piezoelectric or voltage-coefficient effects. As a result, C0G capacitors are commonly used in resonant circuits, filters, and timing references where capacitance stability is more important than volumetric efficiency. Within the broader taxonomy, the CL10C180JB8NNNC sits at the bottom of the passive-component hierarchy: MLCC -> ceramic capacitor -> capacitor -> passive component. Key features of the CL10C180JB8NNNC include a stable 18 pF C0G dielectric, ±5% (J tolerance) capacitance tolerance, 50 V DC rated voltage, an X7R/C0G-style 0603 (1608) footprint (1.6 mm × 0.8 mm), Ni-barrier + Sn-plated termination for lead-free reflow, and RoHS compliance. The small 0603 case and tight tolerance make it well suited to precision analog and RF circuitry where capacitor tolerance directly determines frequency accuracy. The 0603 case size is one of the most common surface-mount MLCC footprints in modern electronics and is supported on virtually every SMT line. The C0G dielectric in this part delivers stable performance across temperature, voltage, and frequency, and it can be used at higher frequencies than X7R or X5R dielectrics because its parasitic inductance and dielectric loss remain low into the GHz range. Like all C0G capacitors, however, it has lower volumetric efficiency (capacitance per volume) than X7R/X5R parts, so designers usually reserve C0G for the small-capacitance, high-stability roles where X7R would be inadequate. Typical applications include RF and microwave matching networks, VCO and PLL tank circuits, crystal-oscillator load capacitors, high-frequency filter networks, precision analog front-ends, and timing circuits. In these roles the 18 pF value often appears as a load or coupling capacitor at frequencies above 100 MHz, or as part of a multi-capacitor network for narrowband filters. Because of C0G's stability, the value does not drift appreciably across temperature or voltage, helping maintain circuit tuning under varying operating conditions. A key design tip: at 18 pF the parasitic inductance of even a short 0603 PCB trace can be a noticeable fraction of the capacitor's impedance above ~1 GHz, so keep the trace from the CL10C180JB8NNNC pad to the active component as short and straight as possible, and use a continuous ground return on the layer below the part. For sub-pF tuning accuracy, consider using only one C0G capacitor per node rather than a parallel combination. This page synthesizes distributor pricing, drop-in alternatives, application notes, and design guidance for the CL10C180JB8NNNC that is not aggregated on any single distributor page.
CL21A106KAYNNNE - 10uF 25V X5R 0805 MLCC | Samsung EM
The Samsung Electro-Mechanics CL21A106KAYNNNE is a 10 µF, 25 V-rated X5R multilayer ceramic capacitor (MLCC) in a surface-mount 0805 (2012 metric) case size, supplied on embossed tape and reel for automated SMT assembly. According to Samsung Electro-Mechanics product documentation and distributor listings from DigiKey and Mouser, this part carries ±10% capacitance tolerance, X5R temperature characteristic, lead-free reflow compatibility, and is qualified across the standard commercial operating-temperature window. An MLCC, or multilayer ceramic capacitor, is a passive component built by stacking alternating thin ceramic dielectric layers and internal metal electrodes. Its primary role is to store and release electrical energy locally while suppressing high-frequency noise and supplying transient current near active circuits. In the component taxonomy, the CL21A106KAYNNNE belongs to the MLCC family, then ceramic capacitors, then capacitors, then passive components, and finally electronic components. The X5R dielectric is a Class II ceramic formulation that balances high volumetric capacitance density with acceptable temperature stability for commercial-grade designs. Key features of the CL21A106KAYNNNE include 10 µF nominal capacitance at 25 °C and 0 V DC bias, 25 VDC rated working voltage, ±10% tolerance over the X5R temperature window, and a standard 0805 footprint measuring 2.0 mm × 1.25 mm. The 25 V rating provides useful margin on common 3.3 V, 5 V, and 12 V supply rails, although engineers must verify that DC bias does not produce unacceptable capacitance loss, the well-known Class II MLCC phenomenon called DC-bias derating. Architecturally, the X5R dielectric uses a barium-titanate-based ceramic with EIA Class II behavior, allowing far higher capacitance density per unit volume than Class I dielectrics (NP0/C0G). The trade-off is a capacitance value that varies non-linearly with applied DC bias, AC voltage, temperature, and aging. Compared with X7R, X5R can deliver higher capacitance density in the same case, although its temperature and voltage coefficients are typically wider; compared with Y5V/Z5U, X5R offers substantially better stability across the operating envelope. Typical applications include microcontroller and DSP power bypass, regulator output smoothing, IoT sensor nodes, mobile-device power paths, industrial control boards, and consumer-electronics filter networks. The part is particularly useful when a design needs more local energy storage than a 0402 or 0603 bypass capacitor can provide while still using a widely supported and easily sourced land pattern. When laying out this capacitor, place it as close as possible to the power pin or signal node it serves. Use short, low-inductance traces and pair it with a smaller high-frequency bypass capacitor when wideband decoupling is required. Always verify effective capacitance under the expected DC bias, temperature, tolerance, aging, and PCB flexure conditions before finalizing the BOM. This page synthesizes manufacturer datasheet data, current distributor pricing, drop-in same-package alternatives, and practical design notes on DC-bias derating and cross-brand substitution for engineers designing with the CL21A106KAYNNNE.
CL21A106KOQNNNE - 10uF 16V X5R MLCC 0805 | Samsung
The Samsung Electro-Mechanics CL21A106KOQNNNE is a 10uF ±10% 16V X5R multilayer ceramic capacitor (MLCC) in an 0805 (2012 metric) surface-mount package. It delivers 10uF nominal capacitance, ±10% tolerance, and a 16V DC rated voltage with X5R temperature characteristic, targeting high-density consumer, industrial, and automotive subsystems where compact size and bulk decoupling performance are required. What is an MLCC? A multilayer ceramic capacitor (MLCC) is a surface-mount passive component constructed from alternating layers of ceramic dielectric and metal electrodes, sintered into a monolithic block and terminated with nickel-barrier solderable end caps. MLCCs are the most widely used capacitors in modern electronics, serving roles in power decoupling, energy storage, AC line filtering, and DC-link bypass. They sit within the broader capacitor family (ceramic -> MLCC -> Class II -> X5R) and are categorized by dielectric class (Class I: C0G/NP0; Class II: X5R, X7R, Y5V) where X5R indicates ±15% capacitance variation over the -55C to +85C operating range. Key features of the CL21A106KOQNNNE include the 0805 (2.0 mm x 1.25 mm) footprint for compact PCB layouts, X5R dielectric for stable bulk capacitance across temperature, 10% capacitance tolerance for general-purpose decoupling, and 16V rating providing ~2x derating headroom for typical 3.3V and 5V rails. The Ni-barrier + Sn plating supports lead-free reflow soldering at 260C peak per JEDEC J-STD-020. Typical applications include IC power-rail decoupling (microcontroller VDD, SoC core supplies), bulk bypass on 5V and 12V regulators, smoothing capacitors in DC-DC converter input/output filters, and general-purpose energy storage in handheld battery-powered products. The 0805 size is widely accepted as a sweet spot between miniaturization and manufacturability. When designing with this part, apply standard 50% voltage derating (so 16V part on a 5V rail provides a 3.2x safety margin), account for DC bias capacitance loss (X5R typically loses 30-50% of nominal value under DC bias at high ratios), and place decoupling capacitors within 2-3 mm of IC supply pins.

CL21B104KCCWPNC - 0.1µF 100V X7R 0805 MLCC | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL21B104KCCWPNC is a 0.1 µF ±10% 100 V X7R multilayer ceramic capacitor (MLCC) in an 0805 (2012 metric) surface-mount package. Built using a nickel-barrier terminations with a tin (Sn) plating over a copper underlayer, the device delivers the standard X7R mid-K temperature characteristic and is rated for operation across -55 °C to +125 °C with ±15% capacitance variation over the rated temperature range. Its 0805 footprint measures 2.00 mm × 1.25 mm, making it one of the most widely adopted chip sizes for general-purpose decoupling and bypass applications. A multilayer ceramic capacitor (MLCC) is a passive surface-mount component constructed from alternating layers of ceramic dielectric and metal electrodes, sintered into a monolithic body and finished with solderable terminations. MLCCs sit in the broader passive component taxonomy as fixed-value capacitors, then specialize by dielectric class (C0G/NP0 for stability, X7R for general purpose, Y5V for high-K bulk capacitance, X5R for portable applications). X7R is the most popular industrial-grade dielectric because it offers a balanced trade-off between volumetric efficiency, temperature stability, and cost. Key features include a 100 VDC rated voltage, ±10% capacitance tolerance (K code), X7R dielectric per EIA-198 classification, and lead-free reflow-solderable terminations compatible with JEDEC J-STD-020 lead-free reflow profiles up to 260 °C peak. The CL21B104KCCWPNC ships on 7-inch paper tape and reel per EIA 481 and qualifies to MSL-1 (unlimited floor life), simplifying logistics for high-volume SMT lines. Internally the device uses a Class-II X7R dielectric whose permittivity drops predictably with temperature and applied DC bias, in contrast to Class-I C0G/NP0 dielectrics that are nearly unaffected by these stresses. The chip also exhibits a typical piezoelectric response that can be audible under certain AC ripple conditions; designers should bias this part appropriately or choose C0G if microphonics matter in the application. Typical applications include decoupling of microcontroller and DSP power pins, general-purpose bypassing around op-amps and ADC references, RC filter networks, snubbers for switching converter edges, and timing/oscillator support stages. The 100 V rating also makes it useful in industrial 24 V / 48 V bus and small-signal coupling paths where higher voltage margin is desirable. When designing with this device, derate working voltage by at least 50% for reliability-sensitive designs, account for DC-bias capacitance loss (typically 10–30% at full rated voltage on small 0805 X7R chips), and place the part within the MLCC keep-out zone under flexure-sensitive pads per IPC-9592 guidelines. This page synthesizes distributor stock and pricing tiers, application-density design guidance, and parametrically matched drop-in alternatives that go beyond what is printed on a single datasheet page, giving engineers a faster path from search to validated BOM.
CL21B106KPQNNNE - 10uF 10V X7R MLCC 0805 | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL21B106KPQNNNE is a 10 microfarad X7R multilayer ceramic capacitor (MLCC) rated at 10 V with a plus/minus 10 percent tolerance, supplied in a standard 0805 (2012 metric) surface-mount package. It provides 10 uF of capacitance in a compact 2.0 mm x 1.25 mm land pattern, making it one of the higher-density energy-storage options for handheld and IoT designs. X7R is a stable mid-K dielectric, offering predictable performance across the -55 C to +125 C operating envelope with capacitance variation limited to plus/minus 15 percent across that range. A multilayer ceramic capacitor (MLCC) is a passive component built by stacking alternating metal electrode layers and ceramic dielectric layers, then co-firing them into a single monolithic block. MLCCs are the dominant capacitor technology for general-purpose decoupling, filtering, and energy storage on modern printed circuit boards because they combine small size, low equivalent series resistance (ESR), low equivalent series inductance (ESL), and excellent high-frequency performance. X7R belongs to the EIA Class II dielectric family, sitting in the broader hierarchy of ceramic capacitor -> MLCC -> Class II -> X7R -> stable mid-K dielectric. Compared with Class I dielectrics such as C0G/NP0, X7R trades some stability for substantially higher volumetric efficiency - i.e. more capacitance per cubic millimeter - which is why it dominates decoupling and bulk-bypass positions. Key features of the CL21B106KPQNNNE include 10 uF nominal capacitance at 10 VDC rated voltage, plus/minus 10 percent capacitance tolerance (K tolerance code), X7R temperature characteristic code, and compliance with RoHS3 / REACH requirements. The 0805 case size (2012 metric) supports automated pick-and-place and is one of the most universally available footprints. MSL 1 (unlimited) rating means there are no special moisture-sensitive handling requirements during PCB assembly. Technically, X7R capacitors exhibit capacitance that decreases with applied DC bias (the DC-bias effect), and the effective capacitance at 5 V on a 10 V-rated part is typically 60-80 percent of the nominal 10 uF. ESR at 100 kHz to 1 MHz is low (tens of milliohms), enabling effective decoupling of digital ICs, and self-resonant frequency is high enough that the part is useful at high frequencies for bypassing. Typical applications include IC decoupling on microcontroller and SoC power rails, bulk bypass capacitance on 3.3 V and 5 V power distribution networks, smoothing at LDO regulator outputs, and general signal-line filtering in consumer, industrial, and IoT electronics. The 0805 footprint and 10 V rating also suit USB, BLE, and Wi-Fi module decoupling networks. When designing with this part, derate the working voltage (commonly to 80 percent or less of rated voltage) to ensure reliability margin, account for DC-bias capacitance loss when computing effective decoupling at operating voltage, and place the capacitor as close as possible to the IC supply pin to minimize parasitic loop inductance.

CL21B224KCFSFNE - 0.22µF 100V X7R 0805 MLCC | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL21B224KCFSFNE is a 0.22 µF (±10%) / 220 nF multilayer ceramic capacitor (MLCC) rated for 100 V, built on an X7R dielectric and packaged in an 0805 (2012 Metric) chip with soft-termination and 125 °C capability. According to the Samsung Electro-Mechanics MLCC catalog, the part delivers stable Class-II X7R performance across the -55 °C to +125 °C operating range, making it a flexible bypass, decoupling, and filtering choice for analog and digital circuits. The "SF" suffix indicates a soft-termination (polymer-based) construction that absorbs mechanical stress from PCB flexure, thermal cycling, and vibration, which is critical for automotive and industrial environments where standard terminations can crack. A multilayer ceramic capacitor (MLCC) is a surface-mount passive that stores energy in alternating layers of ceramic dielectric and metal electrodes, sandwiched between two metal terminations. Within the capacitor taxonomy, MLCCs sit under ceramic capacitors > chip capacitors > surface-mount capacitors > passive components. X7R is a mid-stability Class-II dielectric defined by EIA-198, offering ±15 % capacitance change across -55 °C to +125 °C - a strong trade-off between volumetric efficiency (roughly 10× higher C per volume than C0G/NP0) and temperature stability (less stable than C0G but adequate for most power-rail and signal-coupling duties). Key features include a 100 V DC rated voltage (well above typical 5 V, 12 V, and 24 V rails), ±10 % capacitance tolerance (K-code), 0805 case size (2.0 × 1.25 mm) compatible with standard pick-and-place footprints, soft-termination for mechanical robustness, and an X7R temperature characteristic suitable for automotive, industrial, and consumer designs. The part is supplied on 7-inch tape-and-reel (T/R) per EIA 481 for high-speed assembly. Technically, the X7R dielectric uses a paraelectric barium titanate-based ceramic that delivers high permittivity. The soft-termination is a silver-polymer epoxy layer applied between the nickel barrier and the tin plating, providing strain relief without changing the electrical footprint. The 100 V rating gives generous derating headroom when the cap is used on 12 V, 24 V, or 48 V rails. Typical applications include DC-link and snubber capacitors in 12 V/48 V automotive ECUs, decoupling for MCU/SoC power pins, EMI bypass on industrial sensor modules, and general-purpose filtering in consumer electronics. The 125 °C rating also suits under-hood and outdoor LED lighting. When designing with this part, derate the voltage to ≤50 % of rated (i.e. ≤50 V applied) for long-term reliability under temperature bias. Confirm that the soft-termination variant matches your board's flexure profile - for low-stress consumer boards, a standard-termination 220 nF/100 V X7R part may be sufficient and less expensive.

CL21B472KCANNNC - 4.7nF 100V X7R 0805 MLCC | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL21B472KCANNNC is a 4.7 nF (4700 pF) ±10% X7R multilayer ceramic capacitor (MLCC) rated for 100 V DC, packaged in the industry-standard 0805 (2012 Metric) surface-mount case. It is part of Samsung's CL series of commodity-grade automotive and commercial MLCCs, with dielectric code B (X7R), capacitance code 472 (4.7 nF), tolerance code K (±10%), and termination code N (Ni-barrier + matte Sn plating). The X7R dielectric delivers stable capacitance across -55 °C to +125 °C with ±15% temperature variation, making this part suitable for general-purpose bypass, decoupling, and filtering in analog and digital circuits. A multilayer ceramic capacitor (MLCC) is a passive component constructed by stacking alternating metal electrode layers and ceramic dielectric layers, then sintering them into a monolithic block. MLCCs are the dominant capacitor technology in modern electronics because they offer small size, low ESR, excellent high-frequency performance, and high reliability at low cost. X7R is a Class II dielectric - the second-most-stable MLCC family - trading absolute precision for high volumetric efficiency and moderate temperature stability, which suits applications like decoupling, snubbing, and AC coupling where exact capacitance value is not critical. Key features of the CL21B472KCANNNC include a 100 V rated DC working voltage, ±10% capacitance tolerance, X7R temperature characteristic (EIA code), Ni-barrier + matte tin finish compatible with lead-free reflow soldering up to 260 °C peak (10 s max), and compliance with RoHS/REACH directives. The 0805 (2012 Metric) case measures 2.00 × 1.25 mm land pattern and is one of the most widely adopted SMD capacitor footprints. The CL21B472KCANNNC uses a nickel inner electrode (BME) construction with nickel-barrier terminations to prevent silver migration and ensure solderability after long storage. The matte-tin outer layer prevents tin-whisker growth, an important reliability factor for automotive and long-lifecycle products. Typical applications include general-purpose bypass/decoupling on 5 V, 12 V, and 24 V analog/digital rails, R-C timing networks in oscillators and filters, snubbing across switching-node parasitic inductances, AC coupling in audio signal paths, and energy storage in low-power DC-DC converters. Its 100 V rating provides ample headroom above typical 12 V or 24 V bus rails. When designing with this part, observe the published derating curve (typically 50% of rated voltage for Class II dielectrics) and confirm mechanical pad dimensions match the 0805 land pattern. For high-ripple or high-frequency decoupling, consider paralleling multiple capacitors of different values to broaden the impedance profile.

CL21C680GBANNNC - 68pF 50V C0G 0805 MLCC 2% | Samsung
The Samsung Electro-Mechanics CL21C680GBANNNC is a 68 pF, 50 V, C0G/NP0 multilayer ceramic chip capacitor (MLCC) in an 0805 (2012 metric) surface-mount package with ±2% capacitance tolerance. C0G/NP0 dielectric technology delivers the lowest capacitance change versus temperature (0 ±30 ppm/°C) and zero aging, while supporting a 50 VDC rated working voltage across the -55 °C to +125 °C operating range. The 0805 footprint measures 2.00 mm x 1.25 mm and is supplied in tape-and-reel packaging. A ceramic capacitor is a passive two-terminal component that stores energy in an electric field created by alternating layers of metal electrodes and a ceramic dielectric. Within the ceramic MLCC family, C0G (also written NP0) is the "temperature-compensating" class 1 dielectric defined by the EIA standards; it offers the highest stability, lowest loss (tan δ), and highest Q factor among all ceramic classes. CL21C680GBANNNC belongs to Samsung's CL series — a broad MLCC product line spanning 0201 to 2220 case sizes — positioned inside the wider hierarchy MLCC → ceramic capacitor → capacitor → passive component → electronic component. Key specifications include ±2% capacitance tolerance, a 50 VDC rated voltage, and C0G (NP0) dielectric classification. The 0805 case (EIA 2012) provides compact placement suitable for high-density PCB designs, while the X7R-grade mechanical stability of the part supports standard reflow profiles. Class 1 C0G capacitors exhibit essentially flat capacitance versus DC bias (versus X5R/X7R where DC bias can derate by 30-80%), making them preferred for precision analog filter, RF, and timing circuits. The CL21C680GBANNNC uses a vertically stacked nickel-barrier + tin (Ni/Sn) termination finish compatible with lead-free reflow soldering up to 260 °C peak. The internal monolithic construction is a single ceramic body with screened electrodes, yielding excellent solderability and long-term reliability. The part is qualified to Samsung's standard reliability tests, equivalent to the typical automotive and industrial-grade test regimes, and supports high-speed automated pick-and-place assembly. Typical applications include RF/microwave VCO tank circuits, precision analog filters, ADC/DAC sample-and-hold capacitors, oscillator start-up networks, and high-frequency bypass on sensitive analog nodes. The 68 pF value is commonly used as a load, coupling, or feedback capacitor in the 50-500 MHz band. C0G stability makes the part especially suited to circuits where capacitance drift would degrade performance — for example, PLL loop filters, crystal load capacitors, and impedance-matching networks. When designing, note that a 2% tolerance on a 68 pF part yields ±1.36 pF absolute accuracy — superior to X7R-class 10% or 20% parts of the same value. For PCB layout, place the 0805 pads on a 1.27 mm pitch with adequate clearance for the solder fillets, and respect the manufacturer's recommended land pattern to avoid tombstoning during reflow.

CL31B102KJHNNNE - 1nF 2000V X7R 1206 MLCC | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL31B102KJHNNNE is a 1000 pF (1 nF) ±10% X7R multilayer ceramic chip capacitor rated at 2000 V (2 kV) DC, packaged in the industry-standard 1206 (3216 metric) footprint. It belongs to Samsung's high-voltage CL31B MLCC series, designed for surface-mount applications that demand high insulation resistance and stable performance across a wide temperature range. What is an MLCC? A multilayer ceramic capacitor (MLCC) is a surface-mount passive component constructed of alternating thin ceramic dielectric layers and metal electrode layers fired into a single monolithic body. MLCCs serve five primary roles in electronic circuits: filtering (AC line/DC rail noise), decoupling (local charge reservoir for ICs), timing (RC time constants with resistors), energy storage (snubber and hold-up), and signal conditioning (DC blocking, AC coupling). They sit below resistors, inductors, and ICs in the component taxonomy and are produced in volumes exceeding one trillion units per year globally, making them the most manufactured electronic component on Earth. Key features of the CL31B102KJHNNNE include the X7R dielectric, which provides ±15% capacitance variation across the -55 °C to +125 °C operating range - a balance of volumetric efficiency, voltage handling, and temperature stability well-suited to digital, analog, and power electronics. The 2 kV DC rating is approximately 13× higher than typical 16 V general-purpose 1206 MLCCs, enabling use in circuits where standard-voltage parts would fail or arc. Termination is a nickel-barrier with tin (Ni/Sn) plating, qualified for lead-free reflow soldering up to 260 °C peak per JEDEC J-STD-020. In terms of construction, the device uses a Class II ceramic formulation with internal electrodes screen-printed in parallel to maximize the effective plate area within the 3.2 × 1.6 mm footprint. The chip thickness is approximately 1.25 mm, accommodating the high-voltage dielectric stack. Insulation resistance is specified at ≥10 GΩ or 500 Ω·F (whichever is smaller) per EIA-198, and the dissipation factor (DF) is ≤2.5% at 1 kHz / 1 Vrms / 25 °C. Equivalent series resistance (ESR) is low enough that the capacitor is effectively transparent in DC blocking, snubber, and coupling roles. Typical applications include DC blocking in high-voltage sensor interfaces, snubber networks across flyback transformer secondaries in switch-mode power supplies, EMI filtering on offline LED driver inputs, coupling capacitors in medical defibrillator and patient-monitoring front ends, and bypass/decoupling on 48 V telecom rails. The wide voltage margin also makes it attractive for industrial controls exposed to 230/400 VAC rectified buses where derated DC working voltage is required. AEC-Q200 automotive qualification is not stated for this part; for under-hood or 42 V automotive power-train environments, an AEC-Q200-qualified equivalent should be selected instead. When designing with the CL31B102KJHNNNE, always apply a 50% DC voltage derating for long-term reliability (i.e., hold continuous DC stress below 1000 V for a 2 kV-rated part) and avoid placing it directly adjacent to AC mains traces without adequate creepage clearance. Use the standard 1206 land pattern recommended by IPC-7351, and follow MSL-1 handling (the part is not moisture-sensitive).

CL31B104KEHNNNE - 0.1µF 250V X7R 1206 MLCC | Samsung Electro-Mechanics
Samsung Electro-Mechanics CL31B104KEHNNNE is a 0.1 µF (100 nF) ±10% tolerance, 250 V-rated X7R multilayer ceramic capacitor (MLCC) in a 1206 (3216 metric) surface-mount package. It is part of Samsung's CL31 general-purpose MLCC series, designed for high-volume automated assembly, and provides a stable capacitance over the -55 °C to +125 °C operating temperature range characteristic of X7R dielectric material. A multilayer ceramic capacitor (MLCC) is a passive surface-mount component constructed from alternating layers of ceramic dielectric and metal electrodes, sintered into a monolithic block with external terminations. MLCCs are the most widely used capacitor technology in modern electronics due to their small size, low cost, excellent high-frequency performance, and wide capacitance range. Within the capacitor taxonomy, MLCCs belong to the ceramic capacitor family, which itself sits under fixed capacitors -> passive components -> discrete electronic components. X7R is a Class II dielectric that offers moderate volumetric efficiency (roughly 10× the capacitance per volume versus C0G/NP0) while maintaining acceptable temperature stability (±15 % capacitance change across -55 °C to +125 °C), making it the workhorse dielectric for general-purpose decoupling, filtering, and bypass applications. Key features of the CL31B104KEHNNNE include 250 V DC rated voltage (suitable for 120/220 V mains-derived auxiliary rails and industrial 24 V buses), ±10 % capacitance tolerance (K-code in Samsung's nomenclature), X7R temperature characteristic (X = -55 °C min, 7 = +125 °C max, R = ±15 % capacitance shift), and a 1206 case (3.2 mm × 1.6 mm EIA standard). The Ni-barrier + Sn matte-trim terminations support lead-free reflow soldering up to +260 °C peak. From an engineering perspective, X7R's capacitance decreases with applied DC bias (typically 15-30 % at rated voltage for 100 nF values), and designers should verify effective capacitance at the operating point. ESR remains low (typically under 50 mΩ at 1 MHz) and ESL is in the sub-nH range, supporting effective filtering up to several hundred MHz. The 1206 footprint provides mechanical robustness for hand-prototyping and rework while remaining compatible with high-speed SMT placement. Typical applications include decoupling and bulk filtering in switch-mode power supplies, snubber and timing networks in lighting ballasts, bypass on industrial PLC and motor-driver boards, DC-link filtering on 24 V industrial buses, and general-purpose coupling/filtering in consumer electronics. The 250 V rating also makes it useful as a coupling element across the primary-secondary barrier in offline flyback converters (subject to safety-agency certification). A primary design consideration: confirm the actual in-circuit capacitance under DC bias using the manufacturer's K-Sim or similar bias-characterization tool, especially if the design relies on a specific minimum capacitance value. For noise-sensitive analog stages, place a 0.1 µF X7R 1206 close to each IC supply pin in parallel with a smaller (e.g., 10 nF) C0G/NP0 capacitor for high-frequency decoupling.

CL31B106KAHNNNE - 10uF 25V X7R 1206 MLCC | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL31B106KAHNNNE is a 10 microfarad, 25 volt, X7R dielectric, 1206 (3216 metric) surface-mount multilayer ceramic capacitor (MLCC) rated to plus or minus 10 percent tolerance. It is part of Samsung's general-purpose high-CV MLCC line optimized for automotive and industrial-grade reliability, packaged in a 3.20 mm x 1.60 mm land-pattern compatible 1206 case with nickel-barrier and tin (Sn) plated terminations. What is a MLCC? A multilayer ceramic capacitor (MLCC) is a surface-mount passive component constructed by stacking alternating layers of ceramic dielectric and metal electrodes, then co-firing the assembly into a monolithic block. MLCCs are the dominant capacitor technology in modern electronics because they offer small size, low equivalent series resistance (ESR), high ripple current capability, and excellent high-frequency performance. Within the MLCC family, X7R is a Class II dielectric (defined by EIA RS-198) with stable capacitance across -55C to +125C and plus or minus 15 percent capacitance change over the operating temperature range, making X7R the workhorse choice for general-purpose bypass, decoupling, and filtering where X5R stability is sufficient and C0G/NP0 precision is not required. Key specifications include 10 uF nominal capacitance at 1 kHz and 1 Vrms, 25 V rated DC working voltage, plus or minus 10 percent tolerance, X7R temperature characteristic (EIA code), 1206 (3216 metric) EIA case size, 1.6 mm x 3.2 mm x 0.95 mm typical dimensions, nickel-barrier tin-plated terminations suitable for reflow soldering, and compliance with RoHS3 and REACH. The device is rated for an operating temperature range of -55C to +125C and meets MSL 1 (unlimited floor life) per JEDEC J-STD-020, allowing direct reflow without pre-bake. The CL31B106KAHNNNE is built on Samsung's class-leading high-CV MLCC platform, which uses fine-grained barium-titanate-based ceramic powders and controlled-thickness dielectric layers to achieve high volumetric efficiency. Internal electrode design follows a base-metal-electrode (BME) nickel inner-electrode structure co-fired in a reducing atmosphere, then terminated with a copper barrier layer and tin plating for solderability and lead-free reflow compatibility. This construction supports high inrush current handling and low ESR, which translates to effective high-frequency noise suppression on DC power rails. Typical applications include general IC power-rail decoupling on microcontroller and SoC boards, bulk bypass capacitance on 12 V and 24 V automotive subsystems, low-side filter capacitance in switch-mode power supplies, smoothing capacitors for local point-of-load regulators, and timing/filter elements where moderate capacitance stability is sufficient. Because X7R exhibits significant capacitance loss versus DC bias and temperature, designers should derate effective capacitance in high-voltage or high-temperature regions of the design. When designing with the CL31B106KAHNNNE, note that X7R capacitance drops as applied DC bias approaches the rated voltage; consult the manufacturer's DC-bias characteristic curves to verify effective capacitance at the operating rail voltage. For sensitive analog filter or sample-and-hold nodes, prefer C0G/NP0 dielectrics where capacitance must remain stable with bias and temperature.
