GRM32ER71H475KA88L - 4.7µF 50V X7R MLCC 1210 | Murata
The Murata GRM32ER71H475KA88L is a 4.7µF ±10% 50V X7R multilayer ceramic capacitor (MLCC) in a 1210 (3225 metric) surface-mount package. It belongs to Murata's broad GRM series general-purpose ceramic capacitor line, with the "L" suffix denoting 7-inch embossed tape-and-reel packaging. An MLCC (Multilayer Ceramic Capacitor) is a passive component built from alternating ceramic dielectric layers and metal electrode layers, screen-printed and sintered into a monolithic block. MLCCs are the most widely manufactured capacitor type in the world, used for decoupling, filtering, bypassing, and energy storage. Within the MLCC family, X7R is a Class II dielectric characterized by a stable capacitance over -55°C to +125°C (±15%) and moderate to high volumetric efficiency compared to C0G/NP0 (Class I) dielectrics, which offer tighter stability but lower capacitance density. Key features of the GRM32ER71H475KA88L include a rated DC working voltage of 50V, ±10% capacitance tolerance, X7R temperature characteristic, Ni-barrier + Sn-plated termination for lead-free reflow, and a standard 1210 (3.2mm x 2.5mm) footprint. The part is RoHS-compliant and suitable for general-purpose DC blocking, decoupling, and bypass functions in commercial-grade designs. From an electrical standpoint, the 50V rating provides substantial headroom above typical 3.3V, 5V, 12V, and 24V rails, and the X7R dielectric typically delivers <0.025 dissipation factor and insulation resistance in the GΩ range at 25°C. The 1210 case size is large enough to provide robust mechanical strength and lower ESR than smaller 0805 parts. Typical applications include power-rail decoupling on DC-DC converters and LDO outputs, bulk bypass on FPGA/MCU power pins, audio coupling stages, and general signal-line filtering. The 4.7µF value is a common decoupling point that pairs well with smaller 0.1µF capacitors for broadband noise suppression. When designing with this part, note that X7R capacitors exhibit significant capacitance loss with applied DC bias (often 30–50% derating near rated voltage), and AC ripple current causes self-heating. Verify effective capacitance in-circuit under your actual operating voltage.

HHXA250ARA560MF61G - 56µF 25V Hybrid Polymer Aluminum SMD | Chemi-Con
The Chemi-Con (United Chemi-Con / Nippon Chemi-Con) HHXA250ARA560MF61G is a 56 µF, 25 V conductive polymer hybrid aluminum electrolytic capacitor in a 6.3 × 5.8 mm Radial, Can - SMD package, designed for high-temperature automotive and industrial power-rail decoupling. An aluminum-polymer hybrid capacitor is a type of aluminum electrolytic capacitor that combines a liquid electrolyte with a conductive polymer cathode system. This hybrid construction sits hierarchically between standard aluminum electrolytic capacitors (which use only liquid electrolyte) and pure polymer aluminum capacitors (which use only polymer). The result is a component that offers lower equivalent series resistance (ESR) and higher ripple-current handling than conventional aluminum electrolytic types, while delivering better endurance under high temperature and voltage stress than pure-polymer aluminum parts. Within the broader taxonomy: capacitor -> aluminum electrolytic capacitor -> polymer hybrid aluminum capacitor. Key features of the HHXA250ARA560MF61G include a capacitance of 56 µF at 25 V rated voltage, a capacitance tolerance of ±20%, a maximum ESR of 50 mΩ at 100 kHz, and a rated ripple current of 900 mArms. The device is qualified for 4000 hours of load life at 125 °C and is supplied on embossed carrier tape for automated surface-mount assembly. AEC-Q200 automotive compliance is indicated on Chemi-Con's HXA series datasheet, making the part suitable for under-hood and chassis electronic modules. The hybrid polymer cathode delivers a stable capacitance-versus-temperature characteristic across the -55 °C to +125 °C operating range, with ESR remaining low even at high frequencies. The combination of low ESR and high ripple capability makes the HHXA250ARA560MF61G particularly effective at suppressing high-frequency noise on DC power rails generated by switching converters. Typical applications include automotive ECU power-rail decoupling, DC-DC converter output smoothing, point-of-load (POL) bypass for FPGAs and processors, industrial motor-drive bus capacitors, LED headlamp driver output filtering, and base-station / networking equipment power filtering. The SMD form factor supports reflow soldering and high-density PCB layouts. When designing with this device, derate the ripple current according to ambient temperature using the published temperature-correction factor, and verify that the actual applied DC voltage stays below 25 V including any transient overshoot. Place the capacitor as close as practical to the load IC's supply pin to maximize high-frequency decoupling effectiveness.

KCM55WR72A156MH01K - 15uF 100V X7R Stacked MLCC | Murata
Murata KCM55WR72A156MH01K is a 15 uF, 100 V-rated stacked X7R multilayer ceramic capacitor (MLCC) in a 2220 (5.7 mm x 5.0 mm) surface-mount J-lead package. It is part of Murata's KCM55W series of metal-terminal chip monolithic ceramic capacitors designed for automotive power applications, with ±20% capacitance tolerance and an operating temperature range of -55C to +125C. The stacked internal construction delivers high capacitance density that bulk-tantalum and standard MLCCs cannot achieve in the same footprint. A stacked ceramic capacitor is a component category consisting of two or more ceramic capacitor dies placed inside a single SMT package and bonded in parallel to multiply effective capacitance while maintaining low ESR/ESL. Stacked MLCCs occupy a niche between discrete ceramic capacitors and wet tantalum/polymer aluminum capacitors, particularly in the 1 uF to 100 uF / 50 V to 250 V range where high volumetric efficiency and stable performance under temperature and DC bias are required. Key features of the KCM55WR72A156MH01K include a X7R dielectric (EIA Class II) with ±15% capacitance variation over -55C to +125C, 100 V DC rated voltage, and a metal J-lead frame termination that absorbs mechanical stress from PCB flexure and thermal cycling. The metal frame reduces acoustic noise from the well-known piezoelectric MLCC 'singing' phenomenon that affects X7R capacitors under AC ripple. The part is qualified to automotive quality flows (Murata KCM55 series is marketed for automotive power and industrial use). Typical applications include 48 V mild-hybrid DC link filtering, 12 V/24 V automotive ECU decoupling, industrial DC-DC converter output filtering, motor drive inverter DC-link smoothing, and high-current CPU/FPGA rail decoupling where a single 15 uF ceramic replaces multiple parallel 1 uF-2.2 uF 100 V MLCCs. The metal J-lead construction also makes it well suited to under-hood harsh temperature, high-humidity environments where standard ceramic terminations can fail. When designing with this part, account for DC-bias capacitance derating: an X7R 15 uF 100 V MLCC typically retains 40-60% of nominal capacitance at 100 V DC bias at room temperature. Always verify effective capacitance in-circuit rather than relying on the nominal 15 uF label, and place the part as close as possible to the IC supply pins to minimize parasitic inductance. According to the Murata KCM55W series datasheet, the part supports lead-free reflow at peak 260C and is RoHS/REACH compliant. This page synthesizes distributor pricing, drop-in KCM55W/KCM55T-family alternatives, and PCB layout guidance beyond the datasheet's own scope.
KGM03CR50J225MH - 2.2µF 6.3V X5R MLCC 0201 | KYOCERA AVX
The KYOCERA AVX KGM03CR50J225MH is a 2.2µF multilayer ceramic chip capacitor (MLCC) rated at 6.3V with X5R temperature characteristics, housed in a sub-miniature 0201 (0603 metric) surface-mount package. It delivers a capacitance tolerance of ±20% and operates over the standard X5R range of -55°C to +85°C, making it one of the highest-density bypass solutions available in the smallest commercial MLCC footprint. An MLCC (multilayer ceramic chip capacitor) is a passive component built from alternating thin layers of ceramic dielectric and internal metal electrodes, terminated with nickel-barrier solder coatings for surface mounting. MLCCs sit within the broader capacitor taxonomy of ceramic capacitors -> capacitors -> passive components. The 0201 case (0.6mm x 0.3mm) is the smallest EIA standard MLCC footprint and is critical for decoupling and bulk storage in mobile, wearable, and IoT designs where PCB area is severely constrained. Key features of the KGM03CR50J225MH include its 6.3V DC rated voltage (suitable for downstream-of-LDO rails on 3.3V or 5V systems), a high 2.2µF capacitance value in the 0201 case (a notable density achievement), X5R dielectric which provides stable capacitance across the operating temperature range, and ±20% tolerance (the J suffix per KYOCERA AVX coding). The nickel-barrier terminations support lead-free reflow profiles up to 260°C peak, in compliance with RoHS and REACH directives. The X5R dielectric delivers volumetric efficiency superior to X7R or Y5V in this small case size, but trades absolute stability for size - capacitance can drop 15-25% under DC bias near the rated voltage, a phenomenon called DC bias derating. For noise-sensitive analog nodes, designers should evaluate capacitance at the actual DC operating point, not the nominal 2.2µF. Typical applications include decoupling of low-power SoC power pins, bulk hold-up on wearables and hearables, filter capacitors in compact sensor modules, and bypass on Bluetooth Low Energy and Nordic-style MCUs. It is especially suited to mobile phones, smart watches, hearing aids, and other space-constrained consumer devices. When designing with this part, follow standard MLCC PCB layout practice: use the recommended 0201 land pattern, minimize trace inductance between the capacitor and the IC power pin, and consider DC bias derating in worst-case voltage conditions. Avoid mechanical stress on the ceramic body. This page synthesizes distributor pricing, parametric drop-in alternatives, and engineering application notes beyond what is available on the KYOCERA AVX datasheet, helping engineers select and source this part with confidence.
LMK107BJ106MA-T - 10uF 10V X5R MLCC 0603 | Taiyo Yuden
The Taiyo Yuden LMK107BJ106MA-T is a multilayer ceramic chip capacitor (MLCC) providing 10 uF of capacitance at a 10 V DC rating, with an X5R temperature-stable dielectric and a ±20% tolerance, packaged in a surface-mount 0603 (1608 metric) case. It belongs to Taiyo Yuden's LMK series of medium-high capacitance MLCCs for decoupling and filtering. A multilayer ceramic capacitor is a passive component that stores charge in a ceramic dielectric between alternating layers of nickel and silver-palladium electrodes. MLCCs sit at the base of the passive component hierarchy (capacitor -> ceramic capacitor -> multilayer ceramic chip capacitor) and are the most widely manufactured capacitor type in electronics, valued for small size, low ESR, and reliability. Within power management, MLCCs serve as input/output filters for regulators, decoupling elements next to IC power pins, and DC-blocking components in signal chains. Key features of the LMK107BJ106MA-T include the X5R dielectric, which holds capacitance within ±15% over -55C to +85C, making it suitable for general-purpose decoupling across consumer, industrial, and telecom temperature ranges. The 10 uF value in a compact 0603 footprint reflects Taiyo Yuden's thin-dielectric technology, allowing high volumetric efficiency without moving to a larger 0805 case. The -T suffix denotes tape-and-reel packaging for automated pick-and-place assembly, and the part is RoHS-compliant, lead-free, and compatible with reflow soldering per the manufacturer datasheet. Performance considerations: like all X5R MLCCs, effective capacitance derates with applied DC bias and decreases at higher frequency, so designers should verify the effective capacitance at the actual operating voltage rather than relying on the nominal 10 uF value. ESR is very low (milliohm range), which is beneficial for ripple filtering but can interact with regulator control loops. Typical applications include decoupling of SoC and FPGA power rails, output filtering for DC-DC converters and LDOs, smoothing in portable and battery-powered devices, and bypass filtering in audio and communication equipment. Design tip: use multiple smaller capacitors in parallel and follow the recommended land pattern in the datasheet to manage DC-bias derating and reduce loop inductance. This page synthesizes distributor listings, drop-in cross-references, and practical MLCC design notes not found on the manufacturer datasheet alone.
MAL216259472E3 - 4700µF 100V Snap-In Aluminum Capacitor | Vishay
The Vishay MAL216259472E3 is a 4700 µF, 100 V aluminum electrolytic snap-in capacitor from the 162 RHS series, housed in a radial can with 5 lead snap-in termination and a 40 x 70 mm form factor. It is rated for 5000 hours of load life at 105 °C with a maximum ESR of 38 mΩ at 100 Hz, making it well-suited for high-ripple industrial power applications. The capacitor uses a non-solid electrolyte with a pressure relief vent and is supplied in a polarized, 4-pin (5-lead) snap-in package designed for vertical PCB mounting through 6.3 mm holes on 12.7 mm lead spacing. An aluminum electrolytic capacitor is a polarized passive component that uses an etched aluminum foil anode, a paper separator impregnated with liquid electrolyte, and a cathode foil to form a high-capacitance-per-volume energy storage device. Within the passive component taxonomy it falls under electrolytic capacitors -> capacitors -> passive components, and is generally used for bulk energy storage, DC link filtering, and power-rail smoothing where very high µF values are needed at low cost. The 162 series is purpose-built for switch-mode power supplies, motor drives, and UPS input/output filtering where 100 V to 450 V rails are common. Key features of the MAL216259472E3 include a 20 % capacitance tolerance, an operating temperature range of -40 °C to +105 °C, and a ripple current capability appropriate for the 162 RHS high-ripple series. The snap-in termination provides reliable through-hole mounting with mechanical retention suitable for chassis-mounted and PCB-mounted power sections. Its 4700 µF bulk reservoir is sufficient to hold up a 100 V rail during brief load transients or mains dropouts. Architecturally, the device combines an etched anode foil that maximizes surface area for the dielectric aluminum-oxide layer, a cathode foil, and a borax-based electrolyte absorbed in the separator paper. Compared to solid polymer or film capacitors, the wet electrolytic construction delivers far higher µF/volume at the expense of higher ESR and shorter lifetime, which is acceptable in 105 °C-rated bulk filtering roles. Typical applications include industrial switch-mode power supplies (SMPS), 3-phase input rectifiers and DC link filtering, motor drives, UPS systems, solar inverters, and welding equipment. The 100 V rating aligns with 48 V telecom rails after rectification, 72 V battery stacks, and 3-phase rectified 400 V systems stepped down by intermediate rails. When designing with this part, observe the 5-minute re-voltage procedure for unused capacitors stored more than 6 months, respect the 5 mm clearance around the pressure relief vent, and ensure the 38 mΩ ESR is compatible with the ripple budget. A 1 A/µs dV/dt limit applies; do not place the part directly across a fast-switching node without a damping network.
MKP1840268014 - 6.8nF 100Vdc PP Film Capacitor Radial | Vishay
The Vishay MKP1840268014 is a 6.8 nF (6800 pF) metallized polypropylene (PP) film capacitor rated for 100 V DC continuous operation (with a 63 V AC rating) in a radial-lead through-hole package with 5 mm lead pitch. It is part of Vishay's MKP1840 series, a long-standing family of metallized PP film capacitors optimized for DC link, snubber, and high-frequency filtering roles that demand tight capacitance tolerance and low dissipation. A film capacitor (also called a plastic-film or polymer-film capacitor) is a passive component that stores electrical energy in a thin polymer film such as polypropylene (PP), polyester (PET), or polyethylene naphthalate (PEN). Metallized film capacitors use a vacuum-deposited metal layer as the electrode directly on the film surface, which gives them a graceful self-healing behavior under voltage stress and a smaller package than foil-electrode constructions. Within the broader capacitor taxonomy, MKP1840268014 sits under film capacitor -> plastic-film capacitor -> metallized polypropylene (MKP/PP) capacitor -> DC link/snubber/signal coupling capacitor -> passive component. Key features include a ±5 % capacitance tolerance (EIA standard M-class), stable capacitance across temperature (PP dielectric has a temperature coefficient of roughly -250 ppm/K and very low dielectric absorption), a typical dissipation factor tan(δ) on the order of 0.001 at 1 kHz, and an insulated radial-leaded construction suitable for automated insertion or hand wiring. PP film inherently delivers high insulation resistance, low loss across capacitance, and excellent frequency response, making MKP1840268014 well-suited to applications where capacitance must not change with temperature, frequency, or applied voltage. The MKP1840 series is widely specified as a drop-in PP film capacitor in switched-mode power supplies, electronic ballasts, and audio coupling/decoupling networks where the alternative polyester (PET, MKT) or epoxy-dipped ceramic would distort or drift. Polypropylene's very low dielectric absorption (~0.05 %) makes it preferable for sample-and-hold, AD/DC reference, and analog signal-path designs that must hold a charge accurately. Typical applications include SMPS output filtering after the rectifier, high-frequency snubber networks across switching transistors and rectifiers, DC-blocking in audio signal paths, timing and oscillator circuits, and general-purpose coupling in analog front ends. The 5 mm pitch and 100 VDC rating make it convenient for 24 V and 48 V industrial rails where it functions as a Y-class-like bypass or X-class-like across-the-line filter capacitor (consult the datasheet for safety class certification). When designing with this part, keep lead-forming stress to a minimum so the through-hole terminations do not crack the epoxy seal, and verify the operating AC ripple current and dV/dt against the manufacturer datasheet. For surface-mount designs the MKP1840 series is not the right choice - consider Vishay's MMKP or stacked SMD PP families instead. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes that go beyond the manufacturer datasheet alone, giving buyers and engineers a single source of truth for the MKP1840268014.
Reel - Tape & Reel Packaging Suffix Code | EIA-481-E Standard
The term "Reel" is an industry-standard packaging suffix code (not a standalone component MPN) appended to an integrated circuit's part number to indicate that the device ships on a continuous carrier tape wound onto a 7-inch or 13-inch antistatic plastic reel, conforming to EIA-481-E. This suffix is used by every major IC manufacturer, including Analog Devices (e.g., AD5822BCBZ-REEL, AD827JR-16-REEL, ADM2483BRWZ-REEL, AD1865R-REEL), FTDI (FT232RNL-REEL), and Texas Instruments, to distinguish reel-packaged production quantities from tray, tube, or bulk packaging of the same underlying silicon die. The reel itself is a high-impact polystyrene (HIPS) or polystyrene (PS) carrier designed to protect tape-reeled components from ESD, mechanical shock, and contamination during shipping and automated pick-and-place assembly. Background: EIA-481-E is the Electronic Industries Alliance standard that defines carrier-tape dimensions, pocket spacing, cover-tape peel strength, and reel geometry for surface-mount device packaging. Tape-and-reel packaging enables high-volume SMT assembly by allowing pick-and-place machines to automatically feed components from a continuous tape strip; the reel is the spool on which this tape is wound for storage, transport, and machine loading. Common reel diameters are 7 inches (178 mm) for prototype and small production runs, and 13 inches (330 mm) for high-volume manufacturing. A 7-inch reel typically holds 1,000 to 3,000 components depending on package thickness, while a 13-inch reel holds 4,000 to 10,000+ units. Key features of a compliant antistatic reel include EIA-481-E dimensional conformance, antistatic (surface resistivity 10^6 to 10^11 ohm/sq) High Impact Polystyrene construction, hub compatibility with standard SMT feeder widths (typically 8 mm, 12 mm, 16 mm, 24 mm, 32 mm, 44 mm, 56 mm, 72 mm, 88 mm, and 104 mm), and a manufacturer-proprietary barcode label area for automated traceability. The reel's hub diameter and width must match the carrier tape width exactly to prevent tape deformation during high-speed unwind. Technically, reel selection is determined by the carrier tape width of the device being packaged. SOIC-8 uses 12 mm tape, VQFN-20 uses 16 mm tape, and larger QFP packages may use 24 mm or 32 mm tape. Reels are ESD-safe (typically compliant with ANSI/ESD S541), RoHS-compliant for the polymer materials used, and recyclable under standard polystyrene waste streams. Manufacturer-specific reel part numbers (e.g., ADVPR series from Advantage Carrier Tape, 3M, or Tek Pak) are interchangeable as long as EIA-481-E dimensions match. Typical applications include automated SMT assembly lines for high-volume consumer electronics, automotive ECU production, industrial IoT device manufacturing, and aerospace avionics production. Reels are also used in semiconductor distribution centers for standardized storage and for component replenishment on pick-and-place machines during continuous production runs. When ordering ICs in production quantities, the "-REEL" suffix on the MPN is the standard convention and the same die is supplied as in tube or tray packaging - only the carrier format differs.
SMP253 - Y2 250VAC Class Metallized Paper EMI Suppression SMD | KEMET
The KEMET SMP253 is an impregnated metallized paper EMI suppression capacitor rated for Class Y2 operation at 250 VAC (with variants up to 300 VAC), designed in a surface-mount package optimized for automated assembly. Headline parameters are 250 VAC continuous AC voltage rating, 1500 VDC dielectric withstand voltage, and a capacitance range typically spanning 0.001 µF to 0.047 µF depending on the suffix code, all housed in a rectangular SMD chip footprint with UL 94 V-0 flame-retardant case material. An EMI suppression capacitor (also called a safety capacitor or Y-rated capacitor) is a passive component specifically designed to filter electromagnetic interference on AC mains lines while providing reinforced isolation to protect users from electric shock. Y2-class capacitors in particular are safety-certified for connection between line and earth ground in equipment where failure of the capacitor could not lead to a hazardous electric shock, but where double or reinforced insulation is required. The hierarchy is: capacitor -> film/paper capacitor -> safety capacitor -> Y2 EMI suppression capacitor. Y2 capacitors must pass certified endurance, voltage, and impulse tests per IEC 60384-14. Key differentiating features of the SMP253 include its metallized paper dielectric (versus the more common metallized polypropylene), which provides self-healing behavior and stable capacitance under AC voltage stress. The SMD form factor eliminates the lead wires that typically introduce parasitic inductance in through-hole Y2 capacitors, improving high-frequency filtering performance. A flame-retardant epoxy case rated UL 94 V-0 ensures the part meets safety agency flammability requirements. The series is qualified for automotive-grade applications under the AEC-Q200 stress test standard. Typical applications for the SMP253 include AC line filtering in switch-mode power supplies (SMPS), input EMI filters for industrial motor drives, Y-capacitor placement across isolation barriers in offline LED drivers, USB-PD adapters, and Class II consumer appliances requiring reinforced insulation. The SMD package is particularly valuable in high-volume automated assembly where through-hole safety capacitors would require additional wave-soldering steps. A key design consideration is that Y2 capacitors must be placed only in circuits where the available fault current and transient overvoltages are bounded per IEC 60384-14. Designers should leave adequate creepage and clearance on the PCB and never replace a Y2 capacitor with a non-safety-rated capacitor even if the capacitance and voltage appear to match. For 250VAC continuous operation, the SMP253 is the appropriate selection, while the 300VAC variant is preferred in regions with higher nominal mains voltage.
Samsung CL31B155KAPLNNE - 1.5µF 25V X7R 1206 MLCC | AEC-Q200
Samsung CL31B155KAPLNNE is a 1.5 µF ±10% 25 V X7R multilayer ceramic chip capacitor (MLCC) in a 1206 (3216 metric) surface-mount package, qualified to the AEC-Q200 automotive stress standard. The K temperature characteristic letter indicates ±10% capacitance tolerance over the -55 °C to +125 °C operating range, while the X7R EIA class delivers stable mid-K capacitance (X7R) with predictable temperature and voltage behaviour, suitable for decoupling, filtering, and bulk energy storage. Multilayer ceramic capacitors (MLCCs) are passive two-terminal energy-storage components built from alternating layers of ceramic dielectric and metal electrodes, surface-mountable on a printed circuit board. They sit within the broader hierarchy of ceramic capacitor -> capacitor -> passive component -> electronic component. Within automotive electronics they serve as the workhorse decoupling element, with X7R being the most common mid-K dielectric for general-purpose 1 nF to 10 µF applications that demand moderate volumetric efficiency without the piezoelectric noise or DC-bias collapse associated with Y5V/Y5U/Y5T classes. Key features include a 1.5 µF nominal capacitance with ±10% tolerance, 25 V DC rated voltage (the PL letters indicate an automotive/AEC-Q200 product grade per Samsung's part-number scheme), X7R temperature characteristic (EIA RS-102 / RS-198), and a 1206 (3.2 × 1.6 mm) land pattern compatible with standard SMT reflow profiles at 245 °C peak per J-STD J-020. The 1206 case size provides higher energy density and lower equivalent series resistance (ESR) than smaller 0805 or 0603 parts, while still being small enough for typical automotive ECUs, ADAS sensor boards, and powertrain modules. From an engineering standpoint, X7R MLCCs exhibit DC-bias capacitance loss - the 1.5 µF nominal drops measurably at applied DC voltage - so engineers should consult the AVCC section of the Samsung datasheet and derate capacitance by 30-50% for bulk-2-decade applications. The PL suffix confirms AEC-Q200 qualification, meaning the part has passed thermal-shock, vibration, and biased-humidity stress tests required for automotive use. Typical applications include automotive ECU decoupling, ADAS radar/sensor power-rail bypass, powertrain control modules, and AEC-Q200 in-class automotive electronics. It is also used in industrial DC-DC converter output filters and consumer-grade bulk decoupling where X7R stability is preferred over Y5V. Designers should account for DC-bias derating at 25 V - actual capacitance at rated voltage is typically 30-50% lower than the 1.5 µF nominal. Use a 1 µF effective capacitance budget for bulk-2-decade filtering, to avoid DC-bias undershoot surprise. This page synthesises distributor pricing, drop-in alternatives within the same 1206 footprint, and practical design guidance not found in the bare manufacturer datasheet.
T491A106K010AT - 10uF 10V Tantalum Capacitor 1206 | KEMET
The KEMET T491A106K010AT is a 10 uF solid tantalum capacitor rated at 10 V with a 10% tolerance and 3.8 Ohm ESR, housed in a molded SMD 1206 (3216 Metric, EIA Case A, 3.2 x 1.6 x 1.6 mm) package. A solid tantalum capacitor is a polarized capacitor that uses tantalum metal as the anode with manganese dioxide (MnO2) as the solid electrolyte. Within the passive component hierarchy, it belongs to the capacitor family alongside ceramic and aluminum electrolytic types, and it is valued for high volumetric capacitance, stable electrical parameters over temperature, and no dry-out failure mode. The T491 series is KEMET's industrial-grade MnO2 molded tantalum line, designed specifically for highly automated surface-mount assembly processes. Key features of the T491A106K010AT include a rated voltage of 10 V at 85 C (derated at 125 C), a tight 10% capacitance tolerance (K code), and a specified ESR of 3.8 Ohms, which suits medium-frequency decoupling and bulk filtering. The molded case provides mechanical protection and improved solder-joint reliability versus uncoated chips. The part is RoHS compliant, MSL 1 rated, and supplied tape and reel for automated pick-and-place. Technically, the MnO2 solid electrolyte is self-healing: fault sites convert MnO2 to lower-conductivity Mn2O3, limiting catastrophic short-circuit risk compared with wet electrolytics. Capacitance remains stable across -55 C to +125 C, making the series suitable for demanding industrial environments. Typical applications include general-purpose power-supply input/output filtering, power decoupling for microcontrollers and FPGA rails, and industrial instrumentation where board space and reliability matter. When designing, apply proper voltage derating - KEMET recommends operating at 50% or less of rated voltage for maximum reliability in high-impedance circuits - and observe correct polarity, since reverse bias degrades the dielectric.

T491D106K016AT - 10uF 16V Tantalum SMD Cap | KEMET
The KEMET T491D106K016AT is a 10 uF molded solid electrolytic (MnO2) tantalum capacitor with a 16 V DC rating and 10% capacitance tolerance, supplied in the industry-standard D case (2917 / 7343 metric, 7.3 x 4.3 mm) surface-mount package. It belongs to the T491 series, KEMET's benchmark family of solid tantalum chip capacitors designed specifically for highly automated surface-mount assembly processes. A solid tantalum capacitor is a polarized fixed capacitor that uses tantalum metal as the anode and manganese dioxide (MnO2) as the solid electrolyte, replacing the wet electrolyte of aluminum electrolytic types. Within the passive-component hierarchy, it sits under capacitors, then electrolytic capacitors, then tantalum capacitors. Compared with MLCCs, tantalum types offer high volumetric efficiency and stable capacitance independent of applied DC bias. Key features of the T491D106K016AT include its molded construction for mechanical robustness during reflow, 100% surge-current testing in the T491 series flow, and the wide availability of the D case footprint shared across the T491 family. The 16 V rating provides comfortable derating margin when used on 5 V or 12 V rails, following the common practice of applying the part at 50% or less of rated voltage for maximum reliability. Technically, the solid MnO2 electrolyte gives the device a defined, benign failure mode relative to older wet-tantalum designs, and its capacitance remains essentially stable under DC bias, unlike class II ceramic dielectrics. The K designation denotes the 10% tolerance, tighter than the M (20%) option, simplifying timing and filtering calculations. Typical applications include decoupling and bulk energy storage on microcontroller and FPGA power rails, output filtering of low-voltage DC-DC converters, and analog supply bypassing in industrial, telecom, and consumer boards where PCB space and reliability matter. Design consideration: tantalum capacitors are polarized, so reverse-voltage exposure must be avoided, and derating of applied voltage is recommended.

T491D107K016AT - 100uF 16V 10% Tantalum Cap | KEMET | 2917
The KEMET T491D107K016AT is a solid molded tantalum capacitor with 100 uF capacitance, 16 V DC rated voltage, and +/-10% tolerance, packaged in the industry-standard 2917 (7343 Metric) D-case footprint. It uses MnO2 cathode technology with an ESR of 700 mOhm at 100 kHz and operates across a temperature range of -55C to +125C. A tantalum capacitor is a type of electrolytic capacitor that uses tantalum metal as the anode and a manganese dioxide (MnO2) or polymer cathode. It belongs to the polarized-capacitor family within passive components, sitting under the hierarchy passive component -> capacitor -> electrolytic capacitor -> tantalum capacitor. Compared to aluminum electrolytics of the same capacitance, tantalum parts deliver higher volumetric efficiency, lower ESR, longer operational life, and stable electrical performance across a wide temperature range, which is why they are widely used in DC power rails, decoupling, and filtering of low-voltage digital circuits. Key features include 100 uF capacitance, 16 V rated voltage, 10% tolerance, 700 mOhm ESR at 100 kHz/25C, leakage current of 16 uA max at 25C (0.01 CV or 0.5 uA/uF whichever is greater), and a 7.3 mm x 4.3 mm x 2.8 mm molded epoxy body. The part is rated for 2000 hours of continuous load life at 85C at rated voltage, with 1 cycle of -55C to +125C thermal shock per MIL-STD-202. The D-case footprint (EIA 7343-31) is one of the most common tantalum SMD footprints, enabling direct replacement on existing PCB land patterns. The T491 series uses a sintered tantalum anode pellet with a manganese dioxide cathode coating and a flame-retardant molded epoxy case. Internal construction includes welded tantalum wire leads and silver-loaded epoxy terminations on the anode and cathode faces, with polarity clearly marked on the body by an anode-bar indicator. Typical applications include DC power-rail bulk decoupling, point-of-load bypass for ASICs, FPGAs and DSPs, low-dropout regulator output filtering, handheld and portable electronics, USB power conditioning, and industrial control boards. The 16 V rating provides comfortable headroom for 12 V rails or post-bridge rectified supplies. When designing with this part, observe voltage derating: keep steady-state DC voltage at or below 50% of rated voltage for reliability, never reverse-bias, and respect the 125C upper temperature limit. The molded body handles 245C reflow for up to 10 seconds per JEDEC J-STD-020.
TCNT476M016R0150E - 47µF 16V Polymer Tantalum 1210 | KYOCERA AVX
The KYOCERA AVX TCNT476M016R0150E is a 47 uF solid conductive polymer molded tantalum capacitor rated at 16 V with 150 mOhm ESR at 100 kHz, housed in a 1210 (EIA) / 1411 (3528 metric) surface-mount case. It belongs to the AVX TCN Series, which delivers high CV (capacitance-voltage product) per cubic centimeter and is also offered in an undertab J-CAP variant for the highest energy density per cc. A polymer tantalum capacitor is a type of tantalum capacitor in which the conventional manganese dioxide cathode is replaced with a conductive polymer (typically PEDOT). This construction removes the risk of ignition failure that affects MnO2 tantalum parts under voltage surges, while providing much lower ESR, higher ripple current capability, and benign failure mode (the part simply fails open rather than burning). Polymer tantalum sits in the taxonomy: capacitor -> tantalum capacitor -> molded chip tantalum -> polymer tantalum -> surface-mount polymer tantalum. Key features include 47 uF nominal capacitance, 16 V rated voltage, 20% capacitance tolerance, 150 mOhm maximum ESR measured at 100 kHz, and an operating temperature range of -55C to +105C. The molded 1210 case is footprint-compatible with the EIA 1210 land pattern and offers low profile (~1.9 mm typical) suitable for dense PCB layouts under BGAs and near connector shields. Typical applications include decoupling for low-voltage CPU/GPU cores, point-of-load bypass on telecom/networking line cards, bulk hold-up on solid-state drives, and low-profile audio/display modules. The polymer construction makes this part especially attractive where designers want the energy density of tantalum but need the safety and ripple performance of polymer. When designing with this part, derate the applied voltage by at least 20% (target ~12.8 V or less) for steady-state reliability, and reserve the surge headroom for hot-plug and transient events. Avoid placing the part immediately downstream of large inductive loads; the polymer's benign failure mode helps, but series impedance still affects surge exposure.
TMCJ0J106MTRF - 10µF 6.3V 0603 Tantalum Cap | Vishay Sprague
The Vishay Sprague TMCJ0J106MTRF is a 10 µF solid molded tantalum surface-mount chip capacitor rated at 6.3 V DC, packaged in an EIA 0603 (1608 metric) case measuring 1.6 mm × 0.8 mm × 0.8 mm. It uses the J-case size code within Vishay's TMCJ series and carries a ±20% capacitance tolerance with a 10 Ω maximum equivalent series resistance (ESR) measured at 100 kHz. The molded epoxy body provides mechanical robustness for high-density PCB assembly while supporting automated pick-and-place and reflow soldering. A solid tantalum capacitor is a polarized surface-mount capacitor that uses a sintered tantalum pellet anode, a manganese dioxide (MnO2) or polymer cathode, and a solid electrolyte to deliver high volumetric capacitance density and stable electrical performance across temperature. In the broader passive taxonomy, tantalum capacitors sit between ceramic and aluminum electrolytic capacitors - they offer higher capacitance per volume than MLCCs and lower ESR than aluminum electrolytics, but at higher cost and with a requirement for voltage derating to avoid catastrophic failure. The TMCJ family occupies the small-footprint, low-profile end of Vishay's molded tantalum portfolio, targeting consumer, industrial, and portable designs. Key features of the TMCJ0J106MTRF include a 6.3 V DC working voltage with a higher surge tolerance due to tantalum's inherent dielectric strength, 10 Ω maximum ESR at 100 kHz for effective high-frequency decoupling, and a wide operating temperature range typical of molded tantalum parts. The MnO2 cathode system delivers stable leakage current and long-term reliability. Lead-free reflow compatibility and RoHS compliance make it suitable for modern SMT production lines. The architecture uses a pressed tantalum powder anode sintered into a porous pellet, electrochemically formed with a Ta2O5 dielectric, then coated with a MnO2 solid electrolyte and a graphite/silver cathode. Carbon-silver terminations provide solderable end contacts, while the molded epoxy resin overcoat provides environmental protection and polarity identification. This construction yields volumetric efficiency that allows a 10 µF part in a sub-1 mm profile. Typical applications include decoupling and bulk filtering in portable electronics, smartphones and wearables, IoT sensor nodes, handheld medical devices, point-of-load filtering in FPGA and MCU power distribution networks, audio codec power rails, and wearable/fitness product power management. The 0603 footprint allows direct placement next to small ICs. When designing with tantalum capacitors, always apply 50% voltage derating for reliability and observe polarity strictly. Inrush current limiting is also recommended for the application circuit to prevent failure during hot-plug events.
TMK107BJ106MA-T - 10uF 25V X5R 0603 MLCC | Taiyo Yuden
The Taiyo Yuden TMK107BJ106MA-T is a 10 uF multilayer ceramic capacitor (MLCC) rated at 25 V DC with a +/-20% tolerance, built in the compact 0603 (1608 metric) surface-mount package using a high-dielectric X5R ceramic formulation. It is intended for general electronic equipment such as AV equipment, OA equipment, home appliances, and information/communication devices including mobile phones and PCs. A multilayer ceramic capacitor is a passive component that stores charge in a ceramic dielectric between alternating metal electrode layers. MLCCs form the largest volume segment of the passive components market and sit within the broader component hierarchy: MLCC -> ceramic capacitor -> capacitor -> passive component. X5R dielectric is a Class 2 temperature-stable ceramic characterized by a capacitance variation of +/-15% over the -55C to +85C temperature range, making it the standard choice for decoupling and bulk bypass duties where volumetric efficiency matters. Key features of the TMK107BJ106MA-T include its high 10 uF capacitance in a 1.6 x 0.8 mm footprint, a 25 V rating that covers 24 V industrial rails with margin, +/-20% tolerance (M characteristic), and lead-free, RoHS-compatible termination. Compared with older 10 uF solutions such as 1206 parts or tantalum capacitors, this MLCC delivers lower ESR, no dry-out aging mechanism, and significant board-space savings. Technically, the high-dielectric X5R formulation achieves this capacitance density by using a barium-titanate-based ceramic with thin dielectric layers and nickel internal electrodes. Designers must account for DC bias derating: like all Class 2 MLCCs, effective capacitance decreases as applied DC voltage approaches the rated voltage, a characteristic documented in the manufacturer datasheet and simulation tools. Typical applications include power-supply input and output bulk decoupling for DC-DC converters, decoupling of FPGAs and microcontrollers, mobile phone power distribution, and general board-level bypass. Its 25 V rating makes it suitable for 12 V and 24 V rail environments where lower-voltage 0603 parts such as the 6.3 V JMK107BJ106MA-T cannot be used. A key design consideration is piezoelectric acoustic noise (singing) in Class 2 dielectrics and the DC bias effect, so verification of effective capacitance at operating bias is recommended before finalizing values. Avoid flex-crack exposure by minimizing board bending near capacitor locations.

UWT1V101MCL1GS - 100uF 35V SMD Aluminum Capacitor | Nichicon
The Nichicon UWT1V101MCL1GS is a 100uF 35V surface-mount aluminum electrolytic capacitor in a 6.3mm x 7.7mm Radial Can-SMD package, qualified to the AEC-Q200 automotive stress-test standard and compliant with the RoHS directive (2011/65/EU, (EU)2015/863). The series carries 1000 hours of rated life at 105C and offers a wide operating temperature range of -55C to +105C, making it a workhorse part for general-purpose and automotive-grade DC rail filtering. The '1V' in the part number designates the 35V rated working voltage, and the 'GS' suffix denotes 6.3mm can diameter with Ni-barrier reflow-solderable terminals on a carrier tape. An aluminum electrolytic capacitor is a polarized wet-electrolyte storage element in which an etched aluminum anode and a cathode foil separated by a paper spacer are wound into a cylindrical can and impregnated with an electrolyte. It belongs to the broader electrolytic capacitor family and the still-broader capacitor hierarchy (capacitor > electrolytic capacitor > aluminum electrolytic capacitor > SMD aluminum electrolytic capacitor). Within power management circuits the UWT sits between the switching regulator output node and downstream loads as a bulk-decoupling and energy-storage element, where its high volumetric efficiency per microfarad and cost-per-volt-second outweigh its higher ESR compared with ceramic or polymer alternatives. Key features include 100uF nominal capacitance at +/-20% tolerance, 35V rated DC working voltage, 0.084A (84mA) maximum ripple current rating at 120Hz, and a vertical SMD form factor with surface-mount compatible leads that are auto-insertion ready. The Ni-barrier termination supports lead-free reflow profiles to J-STD-020, while the external can is sleeved for marking and identification. The radial can-SMD geometry offers higher ripple-current handling and capacitance density than comparable tantalum or polymer chip capacitors in the same footprint. Technically, the UWT1V101MCL1GS uses a high-purity etched aluminum foil anode with a controlled-oxide dielectric layer to achieve the stated capacitance in the 6.3mm x 7.7mm can, while the liquid electrolyte provides the cathode connection and self-healing behavior that distinguishes aluminum electrolytics from solid polymer types. Designers select the UWT family when they need a robust, low-cost bulk capacitor that survives automotive thermal-cycling profiles and complies with the RoHS substance restrictions that prohibit lead, cadmium, and certain phthalates. Typical applications include 5V/12V/24V automotive ECU power-rail bulk filtering, DC-DC converter output smoothing after a switching regulator, LED driver input and output capacitance, and industrial control board general-purpose filtering where AEC-Q200 qualification is required. The combination of small case size, wide temperature rating, and reflow compatibility allows direct placement on dense, mixed-technology PCBs in place of older through-hole parts. When designing with this part, always observe polarity - the cathode stripe and shorter lead indicate negative - and ensure that the peak ripple current stays below 84mA at 120Hz for reliable operation within the 1000-hour 105C lifetime rating. For longer-life or higher ripple applications, consider the Nichicon UWD series (2,000 hours) or UVR series (5,000 hours) in the same case size. Verify that the working voltage derates with temperature per the datasheet, and always use a ceramic bypass in parallel for high-frequency decoupling above the electrolytic's self-resonance point.
VJ1206A100KBCAT4X - 10pF 200V C0G 1206 High-Voltage MLCC | Vishay
The Vishay Vitramon VJ1206A100KBCAT4X is a high-voltage surface-mount multilayer ceramic chip capacitor (MLCC) rated at 10 pF with a ±10% tolerance and a 200 V DC working voltage, packaged in the industry-standard 1206 (3216 metric) footprint. It uses C0G (NP0) dielectric, the most stable Class-1 ceramic system available with a temperature coefficient of 0 ±30 ppm/°C across the full -55°C to +125°C operating range and essentially zero capacitance drift with voltage, frequency, or time. The VJ1206A100KBCAT4X belongs to Vishay's patented high-voltage MLCC family that uses an internal surface arc-over prevention construction, allowing reliable operation at the 200 V rating in the compact case size. It is supplied on 7-inch Tape & Reel (T4X suffix indicates 4 mm pitch reel packaging) for automated pick-and-place assembly. A Class-1 ceramic capacitor such as C0G/NP0 is the gold-standard passive component for applications where capacitance stability, low loss, and high insulation resistance are mandatory. C0G parts are commonly placed in resonant circuits, RF filters, precision analog filters, sample-and-hold networks, and high-impedance timing circuits where any capacitance shift would detune the circuit or inject noise. The 1206 case size is the mid-range EIA footprint, offering higher voltage and energy handling than 0402/0603/0805 while still reflowing with standard surface-mount profiles. The headline specifications of 10 pF capacitance, ±10% tolerance, 200 V rated voltage, and C0G dielectric make this part suited to RF coupling/bypass, snubber networks, and high-voltage analog front ends. The 1206 (3.20 × 1.60 mm) footprint allows higher voltage-withstand than smaller 0805 (200 V) or 0603 (200 V) equivalents at comparable capacitance values, because the dielectric layer spacing and electrode overlap area are larger. Insulation resistance is ≥100 GΩ or 1000 Ω-Farads per EIA standard, and the dissipation factor is ≤0.1% at 1 MHz 1 Vrms. Key applications for VJ1206A100KBCAT4X include RF and microwave signal-chain coupling, DC blocking in high-voltage analog front ends, snubber networks across switching power devices, sample-and-hold capacitors in precision ADCs, and crystal/oscillator load capacitors. Compared to Class-2 ceramics (X7R, X5R), C0G exhibits no piezoelectric microphony effect, making it preferable in low-noise audio and instrumentation amplifier circuits. When designing with this device, derate a margin against the 200 V rating to extend reliability - typically 50% voltage derating (i.e. operating below 100 V) for long-life industrial applications. The 1206 footprint supports hand-soldering and standard reflow profiles (peak 260°C per JEDEC J-STD-020). No polarity is required and the termination finish is nickel-barrier with matte-tin plating compatible with lead-free reflow.
