CL31B106KBHNNNE - 10µF 50V X7R 1206 MLCC | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL31B106KBHNNNE is a 10 µF ±10% 50 V X7R multilayer ceramic capacitor (MLCC) in the industry-standard 1206 (3216 metric) surface-mount case, designed for bulk-decoupling and filtering across automotive, industrial, and consumer power-supply designs. It delivers 10 µF nominal capacitance at 50 V rating in a 3.2 mm × 1.6 mm footprint with Ni/Sn lead-free terminations, satisfying JEDEC J-STD-020 MSL-1 moisture sensitivity for unlimited floor life. An MLCC (Multilayer Ceramic Capacitor) is a passive component built from alternating thin ceramic dielectric layers and stacked metal-electrode layers, terminated with a nickel barrier and a tin outer finish for lead-free solderability. Within the broader passive-component taxonomy, MLCCs sit alongside aluminium electrolytic, tantalum, and film capacitors, offering the lowest equivalent series inductance (ESL), the lowest equivalent series resistance (ESR), and the best high-frequency behaviour of any capacitor class. The hierarchy reads MLCC → ceramic capacitor → capacitor → passive component → electronic component. The X7R dielectric is a Class-II (mid-k) formulation with ±15% capacitance change across the -55 °C to +125 °C operating range, and is the workhorse choice for general-purpose decoupling, filtering, and bulk energy storage where C0G/NP0 stability is not required. Key features include 10 µF nominal capacitance in the compact 1206 case, K-tolerance (±10%) for standard industrial precision, and a 50 V rating that delivers generous headroom for 24 V and 48 V rail-bypass applications. The Ni/Sn termination (Samsung EM's standard 'N' finish) ensures excellent leach resistance and solder-joint strength during lead-free reflow profiles up to 260 °C. The 'BH' packaging code designates 7-inch tape-and-reel as the standard shipping format, while the trailing 'E' denotes the RoHS-compliant environmental designation. Technically, the part exhibits noticeable DC-bias derating typical of X7R Class-II dielectrics: at full-rated 50 V DC the effective capacitance can drop substantially from nominal, so designers must de-rate when targeting high-voltage rails. The 1206 case provides enough dielectric volume to deliver 10 µF at 50 V in a footprint that fits beneath most QFN, SOIC, and TQFP power-rail pin fields, while keeping ESR in the low-milliohm range for switching-regulator output ripple suppression and high-frequency decoupling above 1 MHz. Typical applications include 48 V telecom bus decoupling, bulk bypass for USB-PD controllers, motor-driver snubbers, switch-mode power supply output smoothing, and general-purpose power-rail filtering. The 125 °C upper temperature rating also makes it a candidate for under-hood automotive subsystems and industrial LED-driver output stages when paired with a thermal derating margin. When designing with this part, place the capacitor as close as possible to the IC supply pin, use wide power traces to minimise loop inductance, and parallel multiple capacitors when the application demands both high bulk capacitance and low impedance across a wide frequency range. Always verify DC-bias derating from the manufacturer curve at your application's applied voltage, because X7R 10 µF/50 V parts commonly lose 60-80% of nominal capacitance at full rated voltage.

CL31B155KBHVPNE - 1.5µF 50V X7R 1206 MLCC | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL31B155KBHVPNE is a 1.5 µF ±10% 50V X7R multilayer ceramic capacitor (MLCC) in a 1206 (3216 metric) surface-mount package, qualified for automotive-grade applications per the AEC-Q200 standard. It is part of Samsung's CL automotive series, designed for high-reliability circuits where stable capacitance over temperature, voltage, and time is mandatory. What is an MLCC? A multilayer ceramic capacitor (MLCC) is the most widely used capacitor technology in modern electronics, consisting of alternating layers of ceramic dielectric and metal electrodes stacked into a compact surface-mount body. Within the capacitor taxonomy (MLCC -> ceramic capacitor -> fixed capacitor -> passive component), X7R is a mid-stability Class II dielectric defined by the EIA RS-198 standard: ±15% capacitance variation over -55 °C to +125 °C and ±15% over the rated voltage range. This places X7R between high-stability C0G/NP0 (near-zero TC) and high-capacitance Y5V/Z5U (poor stability), making it the workhorse choice for decoupling, filtering, and bulk energy storage. Key features of the CL31B155KBHVPNE include 1.5 µF nominal capacitance, 50 VDC rated voltage, X7R temperature characteristic, ±10% capacitance tolerance, and a 1206 case size (3.2 mm × 1.6 mm). The automotive AEC-Q200 qualification makes it suitable for under-the-hood, body, and chassis electronics. As a Class II MLCC, expect significant capacitance loss with applied DC bias — derate by 30–60% in 50 V designs. The 1206 footprint provides robust mechanical strength and high current handling versus smaller 0402/0603 cases. Typical applications include automotive ECU decoupling, ADAS sensor filtering, 48 V mild-hybrid DC-Link support, industrial SMPS output filtering, and consumer electronics power rails. For low-impedance bulk decoupling at 50 V rails, X7R 1206 1.5 µF outperforms smaller-case MLCCs by an order of magnitude in voltage coefficient. When designing with this part, derate capacitance for DC bias (typical 1.5 µF at 0 V becomes ~1.0 µF at 50 V), verify the ripple current against the 1206 thermal limit, and follow X7R derating guidelines above 80% of rated voltage for long-term reliability. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes — including DC bias derating curves and AEC-Q200 application context — that are not consolidated in the manufacturer datasheet.
CL31B155KOFNFNE - 1.5uF 16V X7R MLCC 1206 | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL31B155KOFNFNE is a 1.5 uF ±10% 16V X7R multilayer ceramic capacitor (MLCC) in a 1206 (3216 metric) surface-mount package. It uses the Samsung CL series base metal electrode construction with X7R (EIA) dielectric, providing a stable ±15% capacitance change over the -55C to +125C operating range. The device is qualified to AEC-Q200, making it suitable for automotive-grade decoupling and bypass applications. A multilayer ceramic capacitor (MLCC) is a passive surface-mount component composed of alternating layers of ceramic dielectric and metal electrodes, terminated at both ends with nickel-barrier/tin plating. MLCCs are the most common capacitor type in modern electronics, used for decoupling, bypass, filtering, and energy storage. The X7R dielectric class delivers medium-to-high capacitance density with reasonable temperature and voltage stability, balancing cost and performance versus X5R (lower temperature range) and C0G/NP0 (lower capacitance but near-zero drift). Key specifications of the CL31B155KOFNFNE include a 1.5 uF nominal capacitance with ±10% tolerance, a 16 V DC rated voltage, X7R temperature characteristic (X = -55C minimum, 7 = +125C maximum, R = ±15% capacitance change), and the standard 1206 (3.20 x 1.60 mm) case size. The 1206 footprint offers a good trade-off between PCB real estate and ESR/ESL performance for general-purpose decoupling. In the Samsung CL31B part-numbering scheme, "CL" denotes the general-purpose MLCC family, "31" identifies the 1206 inch code, "B" marks X7R dielectric, "155" encodes the 1.5 uF value (15 x 10^5 pF), "K" indicates ±10% tolerance, "O" specifies 16V rating, and "F" denotes the standard thickness/series code. The "N" packaging code in the suffix specifies tape-and-reel packaging with 7-inch reel format. Typical applications include 16V rail decoupling in microcontrollers, ASIC/FPGA power pins, USB power delivery bypass, automotive ECU power conditioning, and DC-DC converter output filters. The 1206 case provides mechanical robustness for high-vibration automotive environments while staying within standard SMT pick-and-place tolerances. When designing with this part, derate the working voltage by 50% for long-term reliability, place the capacitor within 1-2 mm of the IC power pin to minimize loop inductance, and consider paralleling with a smaller 0.1 uF capacitor for high-frequency noise suppression. X7R capacitance drops with DC bias, so verify the in-circuit effective capacitance under actual operating voltage. This page synthesizes distributor pricing, drop-in same-family and cross-brand alternatives, AEC-Q200 compliance details, and PCB layout notes that complement, rather than duplicate, the official Samsung datasheet.
CL31B333KHHNFNE - 33nF 630V X7R 1206 MLCC | Samsung Electro-Mechanics
The Samsung Electro-Mechanics CL31B333KHHNFNE is a 0.033 µF (±10%) 630V-rated multilayer ceramic capacitor (MLCC) using X7R dielectric in a 1206 (3216 metric) surface-mount package. It is part of Samsung's high-voltage CL31B series designed for industrial, automotive, and power-conversion applications where stable capacitance under DC bias and elevated temperature is required. What is a multilayer ceramic capacitor (MLCC)? An MLCC is a passive surface-mount component made of alternating layers of ceramic dielectric and metal electrodes, sintered into a single monolithic body. MLCCs sit in the broader taxonomy: passive component -> capacitor -> ceramic capacitor -> MLCC -> Class II (X7R) ceramic capacitor. X7R is an EIA dielectric designation indicating ±15% capacitance variation over the -55C to +125C operating range. Compared to Class I dielectrics (C0G/NP0), X7R offers much higher volumetric efficiency (more µF per mm³) at the cost of less capacitance stability versus temperature, voltage, and frequency. Key features include a 630V DC rated working voltage (suitable for 250-400V AC rectified rails), X7R temperature characteristic (EIA standard), ±10% capacitance tolerance, and Ni/Sn (nickel-tin) termination compatible with lead-free reflow soldering. The 1206 case size provides a good trade-off between physical size and voltage-withstand margin compared to smaller 0805 or 0402 footprints. Technical depth: The CL31B333KHHNFNE uses a high-K barium-titanate-based ceramic dielectric engineered for high-voltage applications. The high capacitance per volume is achieved through many thin dielectric layers stacked in parallel. Compared to Class I C0G capacitors, X7R parts exhibit significant capacitance loss under DC bias (typically 20-40% drop near rated voltage) and aging loss over time, so designers should derate when targeting critical timing or filter applications. Typical applications include snubber and DC-link capacitors in switch-mode power supplies, EMI suppression across hot-side AC mains, gate-driver bootstrap circuits in motor drives and IGBT half-bridges, and high-voltage coupling/decoupling in industrial control and renewable energy inverters. When designing with this device, always observe the 630V working voltage as the maximum continuous DC rating, and add 30-50% safety margin for transient surge handling. Verify that the application's expected inrush and dv/dt transients do not exceed the part's pulse-withstand capability.
ECU-S1J222JCB - 2200pF 63V 5% Ceramic Capacitor | Panasonic
The Panasonic ECU-S1J222JCB is a 2200 pF (2.2 nF) monolithic ceramic chip capacitor rated at 63 V DC with a ±5% capacitance tolerance, packaged in an SMD/ECU-series surface-mount form factor. It uses an X5J temperature coefficient dielectric, providing stable performance across operating conditions typical of general-purpose decoupling, bypass, and filtering roles. A ceramic capacitor is a passive two-terminal electronic component built from alternating layers of ceramic dielectric and metal electrodes. Within the broader passive-component taxonomy, ceramic capacitors sit alongside electrolytic and film capacitors, and they are further sub-categorized into Class 1 (C0G/NP0, high stability) and Class 2/3 (X7R, X5R, Y5V, X5J - higher volumetric efficiency). The ECU-S1J222JCB belongs to the Class 2 family, where X5J is one of several EIA temperature-characteristic codes that defines the capacitance change over the operating temperature range. Key features include the 63 V rated DC working voltage that exceeds the requirement of most 5 V and 12 V digital rails by a comfortable safety factor, the ±5% tolerance that delivers more accurate capacitance than the typical ±10% or ±20% Class 2 parts, and the monolithic construction that reduces equivalent series resistance (ESR) and equivalent series inductance (ESL) versus older leaded ceramic disc parts. The SMD package supports automated pick-and-place assembly. From a technical depth perspective, the X5J dielectric balances volumetric efficiency with moderate temperature stability, making this part well suited for bypass and decoupling where ±10% capacitance drift over temperature is acceptable. The 63 V rating also provides ample margin against transient spikes in 12 V or 24 V automotive/industrial buses, so the part can be used in primary-side filter positions where lower-rated ceramic caps would fail. Typical applications include general-purpose bypass on MCU power pins, RC timing networks where the 5% tolerance matters, analog filter sections in audio and sensor front-ends, snubber networks across switching nodes, and bulk filter caps on low-current rails of industrial controllers. The small SMD footprint also supports high-density PCB layouts typical of modern IoT and consumer designs. When designing with this part, confirm the actual SMD land pattern from the Panasonic ECU-S1 series drawing before laying out the PCB footprint, since several ECU-series codes share similar sizes. Also confirm whether your circuit requires X7R or C0G-grade stability before substituting an X5J part, because the X5J capacitance drift may be too large for precision timer or oscillator circuits. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single source for evaluating the ECU-S1J222JCB in new designs and field replacements.
EECF5R5U155 - 1.5F 5.5V Radial EDLC Supercapacitor | Panasonic
The Panasonic EECF5R5U155 is a 1.5 F electric double-layer capacitor (EDLC), commonly marketed as a supercapacitor or "Gold Capacitor," rated at 5.5 V in a radial through-hole coin-can package. Designed for memory-backup and micro-energy-storage roles, it provides far higher energy density than electrolytic or tantalum capacitors at the cost of higher ESR and lower voltage tolerance. Key parameters include 1.5 F nominal capacitance, 5.5 V rated working voltage, ±80/-20% capacitance tolerance, 30 ohm typical ESR at 1 kHz, and a 1000-hour load life at 70°C. The radial lead configuration simplifies hand-soldering and through-hole PCB insertion, and the device operates across a wide temperature range typical of consumer and industrial backup applications. Background: An EDLC (Electric Double Layer Capacitor), also called a supercapacitor or ultracapacitor, is an electrochemical energy-storage device that stores charge at the interface between a high-surface-area activated-carbon electrode and a liquid or organic electrolyte. Within the energy-storage taxonomy, EDLCs sit between conventional capacitors (very fast, very low capacity) and lithium-ion batteries (slow, very high capacity), trading energy-per-mass for charge/discharge speed and cycle life. They belong to the broader passive-components category of capacitors, and within Panasonic's lineup they are part of the "NF" stacked-coin-type Gold Capacitor family. Key differentiating features include the 5.5 V working rating (which suits one-cell lithium primary or alkaline backup rails), the radial pin/male through-hole termination (which permits hand-soldering or wave-soldering), and the 1000-hour 70°C load life (which exceeds many competing coin-type EDLCs at the same capacity). The ESR of 30 ohm at 1 kHz, while high by aluminum-electrolytic standards, is typical for coin-cell EDLCs of this capacitance class. Typical applications include memory backup for video recorders, audio equipment, cameras, telephones, printers, data terminals, rice cookers, and intelligent remote controllers. Each of these systems needs seconds-to-days of hold-up time to preserve user settings, RTC content, or last-state memory during mains loss — a perfect fit for a 1.5 F / 5.5 V EDLC. When designing with this device, note that EDLCs MUST NEVER be charged without current limiting or a series resistor; inrush into a fully discharged 1.5 F cell can exceed several amps and damage the dielectric interface. Always observe the 5.5 V maximum working voltage, and apply a reverse-blocking diode when paralleling with a primary cell to prevent charging the EDLC above its rated voltage. This page synthesizes distributor pricing, drop-in and cross-family alternatives, and practical backup-circuit design notes not found in the manufacturer datasheet alone.
EEE-FKV121XSP - 120µF 35V SMD Aluminum Electrolytic | Panasonic
The Panasonic EEE-FKV121XSP is a 120 µF, 35 V surface-mount aluminum electrolytic capacitor from the FK-V Series, supplied in a 6.3 mm × 7.7 mm radial-can SMD package with 0.34 ohm equivalent series resistance (ESR) at 100 kHz and a 2,000-hour rated load life at 105 °C. It is AEC-Q200 qualified for automotive applications and rated for reflow-only soldering. The capacitor supports a 20% capacitance tolerance and a 280 mA ripple current rating at 105 °C, making it suitable for moderate-power rail filtering in compact electronic assemblies. An aluminum electrolytic capacitor is a polarized passive component that stores charge through an electrochemical interface between an etched aluminum anode foil, a paper separator impregnated with electrolyte, and a cathode foil. Compared to ceramic or film capacitors, aluminum electrolytics offer very high capacitance density (CV) per unit volume at low cost, which is why they remain the dominant choice for bulk filtering, decoupling, and energy storage in the 10 µF–10,000 µF range above 10 V working voltage. Their trade-offs include higher ESR, polarized operation, and limited high-frequency performance. Key features of the EEE-FKV121XSP include 35 V rated DC working voltage (with appropriate derating to 28–32 V in continuous operation), 120 µF nominal capacitance, 0.34 ohm ESR at 100 kHz, and 2,000 hours endurance at 105 °C. The 6.3 mm × 7.7 mm radial-can SMD form factor makes it compatible with high-density PCB layouts where vertical mount height is constrained. The AEC-Q200 qualification means the part is qualified against automotive stress tests for vibration, thermal shock, and bias humidity, while reflow-only compatibility simplifies reflow soldering onto standard surface-mount pads. Typical applications for the EEE-FKV121XSP include automotive infotainment power rails, ECU 3.3 V/5 V post-DCDC decoupling, industrial 24 V bus hold-up capacitors, and as a switching valve in power modules. The unique features of this part include a low-cost reflow-only land pattern that uses industry-standard reflow connections and supports surface-mount reflow with no need for through-hole lead bending.

EEETG1H100P - 10µF 50V SMD Aluminum Electrolytic | Panasonic
The Panasonic EEETG1H100P is a 10 µF, 50 V surface-mount aluminum electrolytic capacitor from the TG series, packaged in a Radial Can - SMD form factor. It is rated for 1000 hours of load life at +125°C and offers an ESR of 1.6 Ohm measured at 100 kHz, making it suitable for high-frequency filtering in demanding power and automotive environments. The capacitor combines the volumetric efficiency of an SMD aluminum electrolytic with high-temperature endurance required by under-the-hood and industrial power-conversion applications. An aluminum electrolytic capacitor (AEC) is a polarized capacitor that uses an etched aluminum foil anode, an aluminum-oxide dielectric layer formed electrochemically on the anode, and a wet or polymer electrolyte as the cathode. Aluminum electrolytic capacitors belong to the broader family of electrolytic capacitors, which sit within the passive components category. Compared to ceramic and tantalum capacitors, AECs provide much higher capacitance per unit volume and at lower cost, but with higher ESR, higher leakage current, and limited high-frequency performance. Key features of the EEETG1H100P include a 50 V rated working voltage, a 10 µF nominal capacitance, an impedance of 1.6 Ohm at 100 kHz, and a 125°C endurance rating with a 1000-hour load-life guarantee. The part is supplied on tape-and-reel for automated pick-and-place assembly, supports lead-free reflow soldering, and is RoHS/REACH compliant. The TG series uses a hybrid construction combining aluminum foil and a wet electrolyte, optimized for low-impedance/high-frequency operation at elevated temperatures. The radial-can SMD package uses a 6.3 mm x 5.4 mm footprint (case size code B), which is one of the most widely used SMD aluminum electrolytic footprints in 12 V and 24 V input designs. This combination makes the TG series appropriate where engineers want AEC ripple-current capability in an SMD form factor. Typical applications for the EEETG1H100P include DC-DC converter output filtering, point-of-load decoupling after buck regulators, bulk hold-up capacitors in industrial 24 V systems, automotive 12 V power-rail decoupling, and as a bypass capacitor near microcontroller and FPGA power pins where a polarized bulk cap is acceptable. The 125°C rating particularly suits under-hood automotive ECUs, motor-drive auxiliary rails, and LED driver input filtering where PCB ambient temperatures can exceed 100°C. When designing with this part, observe the 50 V maximum DC working voltage and provide at least 30% voltage derating for long-term reliability in continuous-operation scenarios. The SMD radial-can package requires proper land-pattern design to withstand vibration and thermal cycling; verify that the PCB footprint follows the case-size B reference layout to avoid solder-joint fatigue. This page synthesizes distributor pricing, SMD aluminum electrolytic drop-in alternatives from the Panasonic FK and Nichicon UW series, and practical PCB layout notes that go beyond the manufacturer datasheet to help engineers select a drop-in replacement confidently.
EEETK1E221UP - 220µF 25V SMD Aluminum Electrolytic | Panasonic
The Panasonic EEETK1E221UP is a 220 µF / 25 V surface-mount aluminum electrolytic capacitor in the TK series, packaged in a radial-can SMD form factor measuring 8 mm in diameter by 10.2 mm in length (D8 x L10.2 mm). It is rated for 3000 hours of useful life at 125 °C and exhibits a maximum impedance of 300 mΩ at 100 kHz, providing effective high-frequency ripple filtering in compact switching-mode power supply output stages. An aluminum electrolytic capacitor is a polarized energy-storage device in which a formed aluminum oxide layer acts as the dielectric and an ion-conducting electrolyte serves as the cathode. Compared with ceramic capacitors, aluminum electrolytic parts offer much higher capacitance per unit volume and superior energy storage, at the cost of higher equivalent series resistance (ESR), shorter operational life, and polarity sensitivity. EEETK1E221UP belongs to the broader aluminum electrolytic > surface-mount > TK-series taxonomy, optimized for reflow-solder mounting on dense PCB assemblies. Key specifications include ±20 % capacitance tolerance, 25 V DC rated voltage, 197 mA ripple current rating at 100 kHz and 125 °C, and an operating temperature range that supports automotive and industrial environments. The TK-series construction uses a vertical SMD can with standard 8 mm diameter land pattern, enabling drop-in replacement compatibility across the TK-series 220 µF / 25 V family. Typical applications include bulk decoupling at switching regulator outputs, local energy storage for 12 V intermediate bus converters, point-of-load bypass for industrial PLC controllers, and output filtering on DC-DC converter secondary stages. The 25 V rating provides adequate headroom for 12 V automotive and 24 V industrial nominal rails after accounting for transient overshoot. When designing with this part, place it on a copper land pattern sized for the 8 mm can with sufficient clearance for the pressure-relief vent. Verify that ripple current at the actual operating temperature does not exceed the 197 mA rating after frequency and temperature derating. The TK-series is supplied on tape-and-reel and is suitable for automated reflow soldering. This page synthesizes distributor pricing tiers, drop-in alternatives from the same TK family and Nichicon UCZ-series equivalents, and practical design notes not consolidated on the manufacturer product page.

EEH-ZA1E101XP - 100µF 25V Polymer Hybrid SMD Capacitor | Panasonic
The Panasonic EEH-ZA1E101XP is a 100 µF / 25 V conductive polymer hybrid aluminum electrolytic capacitor in a 6.3 x 7.7 mm surface-mount can (radial SMD), offering 30 mOhm ESR and a 10000-hour load-life rating at 105°C. The ZA Series (SMD high-temperature reflow) combines an aluminum electrolytic cathode with a conductive polymer cathode, delivering low ESR and high ripple-current handling in an automotive-qualified (AEC-Q200) package. A conductive polymer hybrid aluminum electrolytic capacitor is a hybrid energy-storage device that uses both an aluminum oxide dielectric and a conductive polymer electrolyte layer. It sits in the hierarchy: aluminum electrolytic capacitor -> hybrid aluminum capacitor -> conductive polymer hybrid aluminum electrolytic capacitor. Compared with standard aluminum electrolytic capacitors, polymer hybrids deliver dramatically lower ESR, longer life at high temperatures, and superior ripple-current capability, while retaining high volumetric efficiency. Key features of the EEH-ZA1E101XP include 100 µF nominal capacitance (±20%), 25 V DC rated voltage, 30 mOhm (or 0.03 ohm) ESR at high frequency, and a 2000 mA ripple-current rating at 105°C and 100 kHz. The device is rated for operation from -55°C to +105°C, supports lead-free reflow soldering up to 250°C, and is qualified to AEC-Q200 for automotive use. The 6.3 mm diameter x 7.7 mm height vertical can with SMD terminals is supplied on tape-and-reel. Technically, the polymer-hybrid cathode replaces the liquid electrolyte of conventional aluminum capacitors, eliminating dry-out failure modes and enabling 10000-hour endurance at 105°C. The 30 mOhm ESR - orders of magnitude below the equivalent liquid aluminum part - reduces I²R losses, lowers self-heating, and allows the part to handle switching-frequency ripple without derating. The rated voltage of 25 V (with derating recommended above 80% VDC for long life) is well matched to point-of-load rails in 12 V automotive and 24 V industrial buses. Typical applications include automotive ECU power decoupling, 12 V point-of-load (POL) filtering in ADAS and infotainment systems, server and telecom hold-rail bulk filtering, and industrial DC-DC converter output smoothing. The AEC-Q200 qualification makes it especially attractive for safety-relevant automotive ECUs. When designing with this circuit, observe the manufacturer's recommended voltage derating (typically ≤80% of rated VDC for maximum life) and respect the 30 mOhm ESR, which is roughly half that of pure polymer aluminum parts but still adequate for most decoupling tasks. This page synthesizes distributor pricing, drop-in alternatives, and application guidance beyond what the manufacturer datasheet provides.
EEUFC1H561S - 560µF 50V FC Series Aluminum Electrolytic | Panasonic
The Panasonic EEUFC1H561S is a 560µF / 50V radial-leaded aluminum electrolytic capacitor from the FC series, optimized for high-frequency / low-impedance operation with a 5000-hour endurance rating at 105°C. Housed in a Φ18mm x 15mm radial can with 7.5mm lead spacing, this polarized wet-aluminum part targets switched-mode power supply (SMPS) output filtering, DC-DC converter post-filtering, and audio amplifier power-rail bypass roles where long-life and low impedance are required. An aluminum electrolytic capacitor is a polarized, wet-electrolyte energy storage device that uses an etched aluminum foil anode, a dielectric aluminum-oxide layer, a paper separator soaked in an organic electrolyte, and a conductive cathode coating to deliver high volumetric capacitance at low cost. They sit in the passive-component hierarchy as: capacitor > electrolytic capacitor > aluminum electrolytic capacitor > radial-lead aluminum electrolytic capacitor, and they remain the dominant choice for bulk energy storage and ripple filtering in the 1µF–100,000µF / 6.3V–450V range where MLCCs become physically or economically impractical. The EEUFC1H561S delivers three headline characteristics: 560µF nominal capacitance, 50V rated DC working voltage, and 5000-hour lifetime at 105°C. Its capacitance tolerance is ±20% measured at 120Hz / 20°C, and DC leakage current is bounded by ≤0.01 CV or 3µA (whichever is greater) after a 2-minute charge period. The FC series is engineered for low impedance at high switching frequencies, making it well suited to the rectified output of secondary-side switching supplies where the capacitor must attenuate high-frequency ripple without excessive self-heating. Internally the device uses Panasonic's etched-foil anode technology with a wet organic electrolyte and a controlled cathode coating that achieves a low equivalent series resistance (ESR) suitable for 100kHz+ switching converters. Compared with the older HD series, the FC series offers lower impedance and ripple-tolerant operation in a comparable can size. The radial through-hole lead geometry provides strong mechanical bonding for wave-soldered assemblies and robust thermal conduction through the leads to the PCB copper. Typical applications include 48V-to-12V / 24V-to-12V SMPS output filtering, secondary-side smoothing of AC-DC rectifier outputs, audio amplifier power-supply bypass, motor-driver bulk-cap roles, industrial control-board decoupling, and LED driver output reservoirs. The 50V rating provides comfortable margin above 24V rectified rails and accommodates 24V nominal automotive transient busses. When designing with this part, observe the ±20% capacitance tolerance and the 3µA / 0.01·CV leakage limit when calculating hold-up times, and verify the ripple-current rating against the actual switching frequency of the converter. The 5000-hour endurance at 105°C derates substantially at higher hotspot temperatures, so thermal modeling of the surrounding heat sources (transformers, MOSFETs, rectifiers) is recommended. This page synthesizes distributor pricing, parametric drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet, providing a single reference for component selection and second-source validation.
GA355DR7GF472KW01L - 4.7nF 250VAC X7R Safety Capacitor | Murata
The Murata GA355DR7GF472KW01L is a safety-certified multilayer ceramic capacitor (MLCC) with a capacitance of 4700 pF (4.7 nF), ±10% tolerance, and a 250 VAC working voltage, packaged in a 2220 (5750 metric) surface-mount case. The part uses an X7R temperature-characteristic dielectric, which provides stable capacitance over the -55 °C to +125 °C operating range with a maximum capacitance change of ±15%. The 2220 case measures 5.7 × 5.0 mm, making it a standard footprint for AC-line safety capacitor applications. A safety capacitor is a discrete component specifically designed and certified for use in circuits that are galvanically connected to the AC mains, where a single failure must not create an electric-shock hazard. Safety capacitors are divided into Class X (across-line) and Class Y (line-to-ground) categories, each with sub-classes that specify the peak pulse voltage they can survive. The GA3 series from Murata carries the X1/Y2 safety rating per IEC 60384-14, allowing it to be used in either position across the AC line or between line and protective earth, which is why it appears in switch-mode power supplies, industrial motor drives, and EV charging interfaces. The X7R dielectric gives the GA355DR7GF472KW01L a useful combination of moderately high volumetric efficiency, predictable temperature behavior, and DC-bias characteristics that are suitable for filtering, snubbing, and decoupling roles in primary-side power stages. Unlike Class-2 Y5V dielectrics, X7R parts retain at least 85% of nominal capacitance across the full industrial temperature window, ensuring consistent EMI-suppression performance in SMPS input filters and across zero-crossing detection circuits. The 250 VAC rating gives sufficient margin for 230 V nominal mains with transient over-voltages up to 2.5 kV peak that occur during lightning-induced surge events. From an electrical standpoint, this part is intended for noise suppression across AC-line terminals (X1 class) and line-to-ground filtering (Y2 class) in switch-mode power supplies, induction-cooktop controllers, photovoltaic inverters, and Class-D audio amplifiers where Class-Y safety isolation is mandatory. Typical insertion loss in a 50 Ω system exceeds 20 dB from 1 MHz to 100 MHz, which is sufficient to attenuate differential-mode and common-mode conducted EMI before it reaches the LISN measurement point. Design considerations include derating for DC-bias capacitance loss: at 250 VDC the effective capacitance is approximately 40-50% of the nominal 4.7 nF. The 2220 footprint requires 1 square cm of bottom-side copper for proper mechanical reliability during thermal cycling, and the recommended land pattern follows IPC-7351 nominal density. When sourcing, always match the trailing suffix (L = standard reel packaging, K = ±10% tolerance) to ensure drop-in compatibility.

GCM155R71H104KE02D - 0.1µF 50V X7R 0402 MLCC AEC-Q200 | Murata
The Murata GCM155R71H104KE02D is a 0.1 µF (100 nF) ±10% 50 VDC X7R multilayer ceramic chip capacitor (MLCC) in the EIA 0402 (1005 metric) surface-mount package, qualified to AEC-Q200 automotive stress-test standards. It delivers 100 nF nominal capacitance at a 50 V rated working voltage from a compact 1.0 mm × 0.5 mm land pattern with an operating temperature range of -55 °C to +125 °C across the X7R dielectric class, and the GCM series designation signals Murata's automotive-grade MLCC line engineered for high-reliability powertrain, chassis, and ADAS electronics. A multilayer ceramic capacitor (MLCC) is a passive two-terminal component that stores energy in an electrostatic field between alternating layers of metal electrodes and ceramic dielectric. In the broader taxonomy this part sits at: capacitor → ceramic capacitor → MLCC → Class II MLCC → X7R → automotive-grade X7R. X7R occupies the engineering middle ground between low-K NP0/C0G parts (zero temperature coefficient, lower volumetric density) and high-K Y5V/Z5U parts (high density but poor temperature and DC-bias stability), which is why X7R is the default dielectric for general-purpose bypass, decoupling, and filtering networks across consumer, industrial, and automotive segments. Key features include the EIA 0402 footprint for sub-0.5 mm pad-pitch layouts, 50 V working voltage, ±10% capacitance tolerance at 25 °C, full AEC-Q200 stress-test qualification for automotive reliability, MSL-1 unlimited floor life, and 7-inch paper-tape packaging per EIA 481 for high-speed SMT placement. The 0402 case enables pad pitches down to 0.5 mm and is the de facto high-density land pattern for bypass networks on modern microcontrollers, SoCs, and CAN/LIN transceivers. Architecturally, the GCM155R71H104KE02D uses stacked barium-titanate-based ceramic layers with screen-printed nickel electrodes co-fired into a monolithic body, then terminated with a nickel-barrier under-layer and matte-tin finish for solderability. The Class II X7R designation reflects a mid-K dielectric whose capacitance is moderate-to-high per unit volume but exhibits predictable DC-bias derating and a modest temperature coefficient (±15% across -55 °C to +125 °C), which engineers must budget for in precision analog filters or timing networks. Typical applications include decoupling automotive ECU microcontrollers, bypassing sensors and CAN/LIN/FlexRay transceivers, ADAS camera and radar power conditioning, and general-purpose filtering on 5 V, 12 V, and 24 V rails. Industrial controllers and factory-automation modules adopt it for compactness and the AEC-Q200 reliability pedigree. When designing with this part, choose 0402 to maximize PCB density but respect 0.5 mm pad-to-pad creepage using 0.2–0.3 mm solder-land extensions. Expect measurable DC-bias derating on X7R parts: applied DC bias of 12–25 V can reduce effective capacitance by 15–50% depending on dielectric lot. This page synthesizes distributor pricing, AEC-Q200 qualification context, drop-in 0402 X7R alternatives, and practical PCB layout notes that go beyond the manufacturer datasheet summary, giving engineers a single reference for sourcing, substitution, and design validation.
GRM155R61A106ME44D - 10uF 10V X5R 0402 MLCC | Murata
The Murata GRM155R61A106ME44D is a 10 uF, 10 V DC-rated multilayer ceramic capacitor (MLCC) in an X5R dielectric, packaged in a 0402 (1005 metric) surface-mount case. It carries a +/-20% capacitance tolerance and is RoHS compliant. An MLCC (multilayer ceramic capacitor) is the most ubiquitous decoupling and bulk-energy storage element in modern electronics, constructed by stacking alternating ceramic dielectric layers and metal electrodes that are co-fired into a single monolithic chip. The X5R dielectric classification (per EIA-198) defines a stable mid-K formulation that retains between +15% and -15% of nominal capacitance across the -55C to +85C operating range, making X5R a workhorse choice for general-purpose bypass, filtering, and coupling on 3.3V to 10V power rails. Key features of the GRM155R61A106ME44D include 10 uF nominal capacitance in a miniature 0402 footprint (1.0 mm x 0.5 mm), a 10 V DC rated voltage, and X5R temperature stability. The device supports a -55C to +85C operating temperature range and is supplied in tape-and-reel packaging optimized for high-speed automated assembly. Its low ESR and high volumetric efficiency make it well suited for decoupling applications where PCB real estate is at a premium. The part leverages Murata's advanced thin-layer dielectric technology to achieve 10 uF in a 0402 footprint that historically housed only 1 uF to 4.7 uF parts. The X5R formulation balances volumetric efficiency against temperature stability - while X5R capacitance will de-rate under DC bias (typical 30-50% loss at rated voltage in this size), the device remains a strong fit for low-voltage digital decoupling where bulk energy storage is the primary requirement. Typical applications include smartphone PMIC decoupling, IoT sensor module bypass, wearable device power-rail filtering, Bluetooth/Wi-Fi module bulk capacitance, and USB Type-C connector VBUS smoothing. The 0402 size makes it a drop-in choice for high-density mobile and consumer designs where every square millimeter matters. When designing with this capacitor, account for DC-bias derating - actual capacitance at 5V may be 50-60% of the nominal 10 uF rating. For applications requiring tighter temperature stability or higher voltage ratings, consider X7R or X7S dielectric alternatives. Verify ripple current and ESR against the manufacturer's datasheet curves for your specific decoupling topology. This page synthesizes distributor pricing, drop-in alternatives from Murata's GRM series and competing MLCC lines, and practical decoupling design notes that complement the manufacturer datasheet.
GRM155R61A475MEAA - 4.7uF 10V X5R MLCC 0402 | Murata
The Murata GRM155R61A475MEAA is a 4.7 uF +/-20% 10 V X5R multilayer ceramic capacitor (MLCC) housed in a 0402 (1005 Metric) surface-mount chip, measuring 1.0 mm x 0.5 mm x 0.5 mm. It is part of Murata's GRM series general-purpose chip monolithic ceramic capacitors, the industry's most widely specified MLCC family for consumer, industrial, and automotive-grade applications. 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 solder coatings. The X5R dielectric (EIA RS-198) provides stable capacitance across -55C to +85C with a +/-15% tolerance band, and offers moderate volumetric efficiency, making X5R the dominant choice for bulk decoupling in 3.3 V to 10 V digital and analog rails. MLCCs sit hierarchically under ceramic capacitor -> capacitor -> passive component -> electronic component. Key features of the GRM155R61A475MEAA include a 4.7 uF nominal capacitance in a compact 0402 footprint, a 10 V DC rated voltage, an X5R temperature characteristic, and +/-20% capacitance tolerance at reference conditions. The device uses Murata's standard nickel-barrier / tin (Ni/Sn) RoHS-compliant terminations suitable for reflow soldering up to 260C peak per JEDEC J-STD-020. With its compact 0402 case size and 4.7 uF rating, the part bridges the gap between smaller 1 uF / 2.2 uF decoupling caps and the physically larger 10 uF / 22 uF options that traditionally required 0603 or larger footprints. Technically, the X5R dielectric in this 0402 package delivers high volumetric efficiency at the cost of significant DC-bias derating - actual capacitance can drop 60-80% under rated DC voltage. Designers must consult the published DC-bias curves from the Murata datasheet before using this part in bulk decoupling roles on rails above 5 V. AC voltage characteristics, temperature coefficient, and aging behavior are all documented in the manufacturer datasheet. Typical applications include bulk decoupling of microcontroller power pins, smoothing on LDO regulator outputs, coupling capacitors in audio signal paths, charge-pump reservoir capacitors, and general-purpose filtering in portable consumer electronics, IoT devices, wearables, and embedded modules. In 0402 format the part is especially useful where board real estate is constrained. When designing with the GRM155R61A475MEAA, verify capacitance under actual DC bias using the Murata DC-bias curves rather than relying on the nominal 4.7 uF value. For 5 V rails with strict ripple budgets, derate by 50% or stack two capacitors in parallel; for 3.3 V rails the nominal capacitance is largely preserved.

GRM155R71C104KA88D - 0.1uF 16V X7R 0402 MLCC | Murata
The Murata Electronics GRM155R71C104KA88D is a 0.1 uF (100 nF) multilayer ceramic chip capacitor (MLCC) rated at 16 V DC with a +/-10% tolerance, built on an X7R temperature-stable Class 2 dielectric in the compact 0402 (1005 metric) surface-mount case size. An MLCC is a passive capacitor formed by interleaving layers of ceramic dielectric and metal electrodes, terminated at opposite ends for surface mounting. Within the component hierarchy, it belongs to the ceramic capacitor family under the broader capacitor category of passive components, and it serves as the workhorse decoupling and bypass element in modern electronics. Because MLCCs are non-polarized, they require no orientation on the PCB, simplifying assembly and enabling use in AC-coupled paths. Key features of this part include the X7R dielectric, which holds capacitance within +/-15% across -55C to +125C, making it suitable for industrial and automotive-adjacent thermal environments. The K stepping code defines the +/-10% capacitance tolerance, tighter than the common +/-20% M-grade parts. The 16 VDC rating provides comfortable margin on 5 V, 3.3 V, and 1.8 V rails, and the small 1.0 x 0.5 mm footprint supports high-density layouts. Technically, X7R is a ferroelectric barium-titanate-based dielectric: it offers far better temperature stability than Y5V/Z5U classes, at the cost of DC bias derating, meaning effective capacitance drops as applied DC voltage approaches the rated value. Designers should verify bias curves when tight capacitance budgets exist. The GRM15 series uses nickel inner electrodes with a lead-free outer termination for reflow soldering reliability. Typical applications include decoupling of microcontrollers, FPGAs, and logic ICs, bypass filtering on power rails, AC coupling, and general-purpose filtering in portable devices, IoT modules, and industrial controls. A key design consideration: keep at least 2:1 DC voltage margin (e.g., use this 16 V part on 8 V rails or lower) to limit X7R bias-induced capacitance loss, and follow IPC land-pattern recommendations for 0402 to minimize tombstoning during reflow.

GRM1885C1H151JA01D - 150pF 50V C0G/NP0 0603 MLCC | Murata
The Murata GRM1885C1H151JA01D is a 150 pF ±5% 50V C0G (NP0) multilayer ceramic capacitor (MLCC) in a 0603 (1608 metric) surface-mount package, part of Murata's GRM series general-purpose ceramic capacitor family. It delivers 150 pF capacitance at 50 VDC rated voltage with Class 1 C0G/NP0 dielectric, the most stable temperature characteristic available in ceramic capacitors (0 ±30 ppm/°C from -55°C to +125°C). The 0603 footprint measures 1.6 mm × 0.8 mm, making it one of the smallest standard MLCC case sizes for high-volume automated assembly. 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 with external terminations. MLCCs are the most widely manufactured capacitor type globally, serving general-purpose filtering, decoupling, bypass, and coupling roles across nearly every electronic system. C0G (also designated NP0) is a Class 1 dielectric, meaning its capacitance is essentially unaffected by temperature, voltage, frequency, or time - making C0G parts the preferred choice for resonant circuits, precision timing, and analog signal paths where stability matters more than volumetric efficiency. Key features include ±5% capacitance tolerance (J code), 50 VDC rated voltage, C0G/NP0 temperature characteristic (0 ±30 ppm/°C), and a 0603 EIA case size. The C0G dielectric ensures minimal capacitance change with DC bias, no piezo-electric noise, and Q factor above 1000 at 1 MHz - ideal for RF and high-frequency analog circuits. The standard 0603 footprint is compatible with high-volume pick-and-place assembly lines. The GRM1885C1H151JA01D utilizes a nickel-barrier tin (NiSn) termination finish for lead-free reflow soldering compatibility, with a 1.0 mm maximum chip thickness suitable for standard 0603 land patterns. The part is RoHS compliant and qualified to Murata's GRM series reliability standards for general-purpose commercial and industrial applications. Typical applications include RF signal coupling and bypass in transceivers, precision timing circuits and crystal load capacitors, analog filter networks, snubber circuits in switch-mode power supplies, and general-purpose decoupling in microcontroller and DSP designs. Its small size and stable C0G dielectric also make it suitable for sensor conditioning, instrumentation amplifiers, and oscillator networks. When designing with this part, confirm that the application operates within the 50 VDC rating and that the PCB land pattern follows IPC-7351 0603 (1608 metric) guidelines. For applications requiring tighter capacitance tolerance (e.g., ±1% or ±2%), specify a C0G part with F or G tolerance code rather than the standard J (±5%) code. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design considerations not consolidated on the manufacturer datasheet alone, including engineering guidance for C0G dielectric selection and 0603 land-pattern layout per IPC-7351.
GRM188R60J106ME47D - 10µF 6.3V X5R 0603 MLCC | Murata
The Murata GRM188R60J106ME47D is a 10 µF ±20% 6.3V X5R multilayer ceramic capacitor (MLCC) housed in an industry-standard 0603 (1608 Metric) surface-mount package. It delivers high volumetric capacitance density with stable performance across a -55 °C to +85 °C operating envelope, making it the workhorse decoupling and bulk-bypass capacitor for consumer, industrial, and portable-electronics designs. What is an MLCC? A multilayer ceramic capacitor is a passive surface-mount component formed by alternating thin dielectric ceramic layers and metal electrode layers, sintered into a monolithic block with termination caps on each end. The 0603 imperial code corresponds to 1.6 mm × 0.8 mm (1608 Metric). The X5R dielectric class (EIA standard) specifies ±15% capacitance variation over -55 °C to +85 °C and a maximum rated temperature of 85 °C, which suits virtually all commercial decoupling rails. MLCCs sit in the taxonomy: capacitor → ceramic capacitor → multilayer ceramic capacitor (MLCC) → SMD passive component. Key features include 10 µF nominal capacitance in the 0603 footprint, 6.3 V DC rated voltage, ±20% capacitance tolerance at 25 °C, X5R temperature characteristic, 1 mm max thickness, and Ni-barrier + Sn plating on copper terminations for lead-free reflow compatibility. Compared with electrolytic alternatives the part offers far lower ESR, zero polarity risk, no dry-out, and RoHS-compliant materials. Technically, the GRM series uses a base-metal-electrode (BME) Ni inner-electrode construction with X5R barium-titanate-based dielectric. BME technology enables the high capacitance per unit volume that defines the GRM Hi-Cap family (1 µF and above). The 6.3 V rating indicates that DC bias derating must be observed: at rated voltage a 10 µF X5R part typically retains 50-70% of nominal capacitance due to the dielectric's voltage coefficient. Typical applications include bulk decoupling on 3.3 V and 5 V logic rails, point-of-load filtering for microcontrollers and SoCs, smartphone and wearable power management, audio codec reference rails, USB/HDMI interface line filtering, and bypass for low-dropout (LDO) regulators and DC-DC converter outputs. The 0603 footprint is the most common land pattern in modern PCB design libraries, ensuring drop-in compatibility with the widest range of reference designs. Design consideration: confirm that the actual DC bias on the rail does not exceed 6.3 V and account for AC ripple; X5R exhibits significant capacitance loss versus DC bias and temperature. For tighter stability, an X7R or C0G alternative at the same 0603 footprint may be preferable on sensitive analog nodes. This page synthesises distributor pricing, drop-in cross-brand equivalents, and practical bypass-layout guidance not found in the bare manufacturer datasheet, supporting faster component selection and BOM risk reduction.
GRM188R71C105KA12D - 1uF 16V X7R 0603 MLCC | Murata
The Murata GRM188R71C105KA12D is a 1 uF multilayer ceramic capacitor (MLCC) with a +/-10% tolerance, a 16 V DC rating, and an X7R temperature-stable dielectric, packaged in a surface-mount 0603 (1608 metric) case of 1.6 x 0.8 mm. It belongs to Murata's GRM series Hi-Cap lineup of chip multilayer ceramic capacitors for consumer electronics and industrial equipment. A multilayer ceramic capacitor (MLCC) is a passive component that stores charge using multiple layers of ceramic dielectric interleaved with metal electrodes. Within the passive-component hierarchy, it sits under capacitors, and within Murata's naming system the GRM prefix denotes a chip MLCC for SMD mounting. MLCCs are the most widely used capacitor class in modern electronics due to their small size, low ESR, and reliability. Key features of this part include the X7R Class 2 dielectric, which maintains useful capacitance from -55C to +125C with a maximum capacitance change of +/-15%, making it suitable for decoupling and bypass roles across the full industrial temperature range. The 16 V rating provides headroom for 12 V rails, and the 0603 footprint offers high capacitance density for dense PCB layouts. The K tolerance code guarantees +/-10% capacitance accuracy. The R71 characteristic code identifies the X7R dielectric within the R series temperature characteristic family. Like all Class 2 ceramics, capacitance derates with applied DC bias and aging occurs over time, so designers should verify effective capacitance at operating bias. Soldering follows standard reflow profiles for 0603 chip components. Typical applications include power-supply input/output decoupling for microcontrollers and FPGAs, general-purpose bypass filtering, DC-DC converter input/output capacitors, and coupling or smoothing in consumer, industrial, and communication equipment. Murata's product page lists transportation, traffic control, disaster prevention/security, and industrial data-processing equipment among target applications. Design consideration: derate the applied DC voltage well below 16 V and account for DC-bias capacitance loss, which on a 1 uF X7R 0603 can be significant at high bias; verify effective capacitance with Murata's SimSurfing tool. This page synthesizes distributor pricing, drop-in alternative options, and practical design guidance not found in the manufacturer datasheet.
GRM188Z71E225KE43D - 2.2uF 25V X7R MLCC 0603 | Murata
The Murata GRM188Z71E225KE43D is a 2.2 microfarad, 25 volt, X7R dielectric, ±10% tolerance multilayer ceramic chip capacitor (MLCC) in an 0603 (1608 metric) surface-mount package, supplied on tape and reel. It is a member of Murata's flagship GRM series, the industry's most widely used general-purpose MLCC family for consumer, industrial, and infrastructure electronics. What is an X7R MLCC? An MLCC (multilayer ceramic capacitor) is a passive component formed by alternating layers of ceramic dielectric and metal electrodes, then sintered into a monolithic block with terminations on each end. X7R is a Class II dielectric defined by EIA-198: it offers moderate capacitance density (much higher than Class I C0G/NP0), with a specified capacitance temperature stability of ±15% across the -55°C to +125°C operating window. X7R is the standard choice for decoupling, filtering, smoothing, and coupling applications where modest temperature variation is acceptable but miniaturization and bulk capacitance are required. Key features of the GRM188Z71E225KE43D include a 2.2 uF nominal capacitance in a compact 0603 footprint (1.60 mm × 0.80 mm, 0.80 mm land pattern), 25 VDC rated voltage, ±10% capacitance tolerance, and a maximum thickness of approximately 0.80 mm (Murata's Z7 characteristic, optimized for high capacitance in small case sizes). It is RoHS and REACH compliant, lead-free, and suitable for reflow soldering up to 260°C peak temperature. The GRM series uses nickel-barrier tin-finish terminations compatible with Pb-free assembly, and is qualified to Murata's rigorous reliability standards, including AEC-Q200 for select part variants. The Z7 voltage-temperature code (X7R dielectric optimized for 25 V rating in 0603 size at 2.2 uF) represents Murata's mature high-density stack technology, enabling this part to serve as a low-cost, high-availability standard decoupling capacitor. Typical applications include power rail decoupling in microcontrollers and digital logic ICs, smoothing on low-dropout (LDO) and buck regulator outputs, audio coupling and bypass in portable devices, USB power line filtering, and general-purpose bypass in IoT nodes, wearables, and consumer appliances. The 25 V rating provides ample margin for 3.3 V, 5 V, and 12 V rails. When designing with this part, derate voltage by 50% (i.e., limit continuous operation to ≤12.5 V) when long-term DC bias reliability is critical, as X7R capacitance drops significantly with applied DC voltage. Place the capacitor as close as possible to IC power pins with short, wide traces to minimize parasitic inductance. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving engineers a single authoritative reference for sourcing the GRM188Z71E225KE43D.
GRM21BR60J476ME15L - 47uF 6.3V X5R 0805 MLCC | Murata
The Murata Manufacturing GRM21BR60J476ME15L is a 47 uF, 6.3 V rated multilayer ceramic capacitor (MLCC) in the 0805 (Imperial) / 2012 (Metric) surface-mount package using an X5R dielectric with +/-20% tolerance. Designed on Murata's general-purpose GRM series platform, this part delivers high volumetric capacitance density for decoupling and bypass applications in compact consumer and industrial electronics. The X5R dielectric offers stable performance over the -55C to +85C operating range with moderate capacitance change (typically +/-15%) across temperature and voltage. Background Knowledge: A multilayer ceramic capacitor (MLCC) is a passive surface-mount component formed by stacking alternating thin ceramic dielectric layers and metal electrodes, then sintering them into a monolithic block with terminations on two opposing ends. MLCCs are categorized by dielectric class: Class I dielectrics (C0G/NP0) offer high stability and ultra-low loss for resonant circuits; Class II dielectrics (X5R, X7R, Y5V) offer much higher volumetric capacitance density at the cost of temperature and voltage coefficient. The 0805 case size (2.0 mm x 1.25 mm) is one of the most widely used SMD footprints, sitting in the standard mid-range between small 0402/0603 bypass caps and larger 1206/1210 bulk-decoupling caps. Key features of the GRM21BR60J476ME15L include 47 uF nominal capacitance, 6.3 V DC rated voltage, +/-20% tolerance, X5R temperature characteristic (EIA standard), 0805 EIA / 2012 Metric case, nickel-barrier with tin (Sn) plated terminations for lead-free reflow, and compliance with RoHS directives. The X5R dielectric allows substantially higher capacitance per unit volume than X7R or C0G at the same footprint, which is critical when board real estate is constrained. Technical depth: At 6.3 V the rated dielectric withstand voltage per Mil/Murata reliability testing is conservative, leaving margin for typical 3.3 V and 5 V rail decoupling. The X5R dielectric shows capacitance roll-off versus DC bias; engineers should consult the manufacturer datasheet's DC bias curves for the actual effective capacitance at the operating voltage. ESR for ESR in the low-milliohm range at high frequency makes the part suitable for high-frequency decoupling of processor and ASIC power pins. The 0805 footprint supports reflow soldering at standard JEDEC J-STD-020 lead-free profiles. Typical applications include bulk decoupling of 3.3 V and 5 V IC power rails, high-frequency bypass for digital processors and ASICs, smoothing on LDO regulator outputs, coupling in audio signal paths, and general-purpose filtering in consumer, industrial, and computing equipment where high capacitance density in a small footprint is required. When designing with this part, derate voltage by at least 30% for reliable long-term operation, account for DC-bias capacitance loss (X5R typically loses 30-60% of nominal value under rated DC voltage), and ensure the PCB land pattern follows IPC-7351 nominal 0805 pad dimensions. Always verify the lot's actual measured capacitance against design assumptions for noise-sensitive analog designs. This page synthesizes distributor pricing, cross-brand drop-in alternatives from verified cross-reference data, and practical design notes that go beyond the manufacturer datasheet alone.
GRM21BR61A476ME15L - 47µF 10V X5R 0805 MLCC | Murata
The Murata GRM21BR61A476ME15L is a 47 µF ±20% tolerance X5R multilayer ceramic capacitor (MLCC) rated at 10 V DC, packaged in an 0805 (2012 Metric) surface-mount case. It is part of Murata's GRM series, the company's flagship general-purpose monolithic ceramic capacitor line used in virtually every segment of the electronics industry. An MLCC (Multilayer Ceramic Capacitor) is a passive component constructed by stacking alternating layers of ceramic dielectric and metal electrodes, then sintering them into a monolithic block. X5R is a Class 2 dielectric defined by EIA-198, offering stable capacitance over -55°C to +85°C with ±15% variation. Compared to Class 1 dielectrics (NP0/C0G), X5R delivers much higher volumetric efficiency, enabling the 47 µF rating in a compact 0805 footprint that would otherwise require a tantalum or electrolytic capacitor. Key features of the GRM21BR61A476ME15L include 47 µF nominal capacitance in a 2.0 mm × 1.25 mm (0805) package, 10 V DC rated voltage, ±20% capacitance tolerance, X5R temperature characteristic, and Ni-barrier + Sn-plate terminations compatible with lead-free reflow. The component is RoHS compliant and qualified to Murata's automotive-grade reliability flow on selected lots. Its 0805 size balances high density with robust solder-joint strength, making it suitable for both hand and automated assembly. In circuit, the GRM21BR61A476ME15L is typically used as a local decoupling capacitor near IC power pins, where it suppresses high-frequency noise and stabilizes the supply rail. The X5R dielectric's high permittivity provides bulk energy storage close to the load, reducing voltage droop during transient current demands from digital logic, microcontrollers, and RF transceivers. Typical applications include smartphone PMIC output filtering, USB Type-C decoupling, IoT sensor modules, MCU bypass networks, wearable device power rails, and consumer audio codec supplies. Designers value the GRM series for its mature supply chain, predictable DC-bias characteristics, and global multi-source availability. When designing with this part, account for DC-bias capacitance loss. X5R 47 µF capacitors can lose up to 70-80% of nominal capacitance under their full rated voltage, so effective capacitance at 10 V may be considerably lower than 47 µF. Always verify bias behavior from the manufacturer datasheet curves when designing timing or filter circuits sensitive to absolute capacitance. This page synthesizes distributor pricing, drop-in alternatives from multiple manufacturers, and practical bias-aware design notes not consolidated in the Murata datasheet alone.
GRM31CR61A476KE15L - 47uF 10V X5R MLCC 1206 | Murata
The Murata GRM31CR61A476KE15L is a 47 µF ±10% multilayer ceramic capacitor (MLCC) in the 1206 (3216 metric) surface-mount case size, rated at 10 V DC with an X5R EIA class-II dielectric. The part belongs to Murata's GRM-series general-purpose MLCC family and is supplied on 7-inch paper tape and reel per EIA-481 with a 4,000-piece standard reel quantity. Nickel-barrier solderable metallization is compatible with lead-free reflow profiles up to 260 °C peak per JEDEC J-STD-020. An MLCC (multilayer ceramic capacitor) is a passive SMD component manufactured by co-firing alternating layers of ceramic dielectric and metal inner electrodes into a monolithic chip, then terminating the two opposing end faces with nickel-barrier solderable metallization. In the passive-component taxonomy it sits at MLCC -> ceramic capacitor -> capacitor -> passive component. MLCCs dominate decoupling, bypassing, filtering, coupling, and bulk energy storage because of their very low equivalent series resistance (ESR), non-polarized construction, no wear-out mechanism, and extreme volumetric efficiency compared with aluminum or tantalum electrolytics. Key features include 47 µF nominal capacitance in a compact 1206 footprint, 10 V DC rated working voltage, ±10% capacitance tolerance, and X5R dielectric per EIA RS-198 classification. The 1206 case size provides thermal and mechanical robustness for hand-solder rework, screw-fastener mounting, and depanelization processes used in mass production. Operating temperature range spans -55 °C to +85 °C, and the part is halogen-free and RoHS compliant per the latest Murata product declaration. The part uses a high-capacitance X5R dielectric stack optimized for moderate-voltage rails. X5R delivers superior volumetric efficiency versus X7R but pays for it with reduced temperature stability and stronger DC-bias derating: effective capacitance under 5 V bias can drop significantly versus the 1 Vrms small-signal measurement condition used to specify the 47 µF rating. Engineers must verify in-circuit capacitance under actual operating bias rather than relying on the nominal number alone, especially for bulk decoupling in 3.3 V and 5 V rails. Typical applications include smartphone PMIC input/output decoupling, 3.3 V and 5 V rail bulk capacitance in tablets, wearables, and USB-C port bypass networks, plus industrial sensor-module power conditioning and IoT endpoint devices operating at 10 V or below. Per the Murata product specification, mechanical board flex beyond 1 mm should be avoided to prevent chip cracking during depanelization or screw-fastener mounting. When designing with this part, evaluate in-circuit effective capacitance under your actual DC bias, because X5R class-II MLCCs lose a substantial fraction of nominal capacitance at high bias. Pair this part with a smaller X7R or C0G capacitor in parallel for high-frequency decoupling when the bulk capacitor's bias derating leaves insufficient low-frequency energy storage.
