04023C104KAT2A - 0.1uF 25V X7R 0402 MLCC | KYOCERA AVX
The KYOCERA AVX 04023C104KAT2A is a 0.1 uF (100 nF) multilayer ceramic capacitor (MLCC) rated at 25 V DC with a +/-10% tolerance, built on an X7R Class 2 dielectric in a compact 0402 (1005 Metric) surface-mount case. An MLCC is a passive component that stores electrical charge between alternating layers of ceramic dielectric and metal electrodes. Within the passive component hierarchy (capacitor -> ceramic capacitor -> multilayer ceramic capacitor -> surface-mount passive), MLCCs are the most widely deployed decoupling and bypass elements in modern electronics because they combine high volumetric efficiency, low ESR, and no polarity. Key features of the 04023C104KAT2A include its X7R temperature-stable dielectric, which holds capacitance within +/-15% across the -55C to +125C industrial temperature range; the 25V DC rating, which covers 24V-rail decoupling with margin; and the industry-standard 0402 footprint for dense PCB layouts. The K tolerance code indicates a tight +/-10% capacitance window, and the part is supplied in 8 mm tape-and-reel packaging for automated pick-and-place assembly. Technically, the AVX 0402 series uses a nickel-barrier termination system compatible with reflow, wave, and vapor-phase soldering, supporting lead-free (RoHS) assembly profiles. The X7R dielectric is a ferroelectric ceramic formulation that trades slight voltage-coefficient capacitance loss for far better temperature behavior than Y5V/Z5U alternatives, which is why X7R is the default choice for decoupling, filtering, and timing networks that must remain stable over temperature. Typical applications include MCU and logic IC supply decoupling, DC bias filtering on sensor and amplifier rails, EMI mitigation on power inputs, and general-purpose bypass in industrial controls, automotive body modules (non-safety-critical), and consumer devices. Design consideration: like all X7R parts, effective capacitance derates under applied DC bias; verify the actual capacitance at your operating voltage and allow margin for aging (X7R ages roughly 1-3% per decade hour).

04023R474K500BA - 0402 X7R 0.47uF 50V MLCC | Kyocera AVX
The Kyocera AVX 04023R474K500BA is a 0402-size multilayer ceramic chip capacitor (MLCC) providing 0.47 uF capacitance, a 50 V DC rating, and a +/-10% tolerance in an X7R Class 2 temperature-stable dielectric, supplied in tape-and-reel packaging for automated surface-mount assembly. A multilayer ceramic capacitor is a passive component that stores charge in a ceramic dielectric layered with alternating metal electrodes. Within the component hierarchy, the MLCC belongs to the capacitor family, which in turn is part of the passive-component class used in virtually every electronic circuit for decoupling, filtering, and energy buffering. Class 2 X7R dielectrics offer moderate capacitance density with defined stability over -55C to +125C and up to +/-15% capacitance change over that range. Key characteristics of this part include its 0.47 uF value in a compact 1.0 mm x 0.5 mm footprint, its 50 V rating suitable for industrial and automotive 24 V-adjacent rails with headroom, and the X7R dielectric that keeps behavior predictable across the full industrial temperature span. The K tolerance code indicates a +/-10% capacitance spread at 25C and 1 kHz. Technically, AVX manufactures this series using a precious-metal or base-metal electrode system with nickel barrier termination for reliable solder wetting in reflow processes; designers should note that X7R capacitance decreases with applied DC bias, so effective capacitance at operating voltage will be lower than nominal. Typical applications include power-supply decoupling for microcontrollers and FPGAs, input/output filtering on 24 V industrial control boards, and general-purpose bypass functions where a stable, small-footprint capacitor is required. Design consideration: because Class 2 dielectrics exhibit voltage coefficient and aging effects, derate the effective capacitance when sizing for a required minimum decoupling value.

04025C501KAT2A - 500pF 50V X7R 0402 MLCC | KYOCERA AVX
The KYOCERA AVX 04025C501KAT2A is a 500 pF multilayer ceramic capacitor (MLCC) rated at 50V DC with a ±10% tolerance, an X7R Class II temperature-stable dielectric, and a 0402 (1005 metric) surface-mount package supplied on tape and reel. A multilayer ceramic capacitor is a passive component that stores charge in alternating layers of ceramic dielectric and metal electrodes. It sits in the component hierarchy under capacitors -> passive components, and MLCCs are the most widely used capacitor type in modern electronics due to their small size, low ESR, and absence of polarity. X7R dielectrics are EIA Class II temperature-stable formulations that maintain usable capacitance across -55C to +125C while offering higher volumetric efficiency than Class I C0G parts. Key features of the 04025C501KAT2A include its 500 pF nominal capacitance suitable for decoupling, filtering, and timing functions; the 50V DC voltage rating that covers 5V, 12V, 24V, and most low-voltage logic rails with margin; ±10% tolerance for predictable circuit behavior; and the compact 0402 (1.0 mm x 0.5 mm) footprint that enables high-density PCB assembly with standard reflow processes. The X7R dielectric in this part exhibits capacitance variation within ±15% over its -55C to +125C temperature range, with additional capacitance reduction under applied DC bias that designers should account for in high-rail applications. This behavior is typical of intermediate-K Class II ceramics and is the principal trade-off against C0G/NP0 parts, which offer zero temperature drift but at roughly one-tenth the volumetric efficiency. As a non-polarized component it can be mounted in either orientation and tolerates standard lead-free reflow profiles. Typical applications include high-frequency supply decoupling for microcontrollers and FPGAs, analog signal coupling and filtering, RF bypass networks, and general-purpose timing circuits where 500 pF values are required. The 50V rating also makes it suitable for industrial 24V systems and automotive sensor signal lines with transient headroom. Designers should verify DC bias and AC ripple derating, and avoid mechanical stress from board flex, which can crack MLCCs; 0402 sizes are less sensitive than larger case sizes.

0402B104K160NT - 100nF 16V X7R 0402 MLCC | Fenghua
The Fenghua (Guangdong Fenghua Advanced Technology) 0402B104K160NT is a 100 nF (0.1 uF) multilayer ceramic chip capacitor (MLCC) rated at 16 V DC with an X7R Class 2 dielectric and a tolerance of plus/minus 10 percent, packaged in the industry-standard 0402 (1005 metric) surface-mount case. An MLCC is a passive capacitor built from alternating layers of ceramic dielectric and metal electrodes, terminated with solderable end caps. As the workhorse decoupling and bypass element of modern electronics, MLCCs form the lowest tier of the capacitor family (capacitor -> ceramic capacitor -> multilayer ceramic chip capacitor -> passive component) and are placed by the millions on SMT boards to stabilize supply rails and filter high-frequency noise. Key features of the 0402B104K160NT include its compact 1.0 mm x 0.5 mm footprint, the temperature-stable X7R formulation (typically plus/minus 15 percent capacitance change from -55C to +125C, as listed in distributor data), and a 10 percent capacitance tolerance that suits decoupling duty where exact capacitance is not critical. The 16 V rating covers 3.3 V, 5 V, and most 12 V rail bypassing with margin. Electrically, X7R dielectric is a barium-titanate Class 2 ceramic: it offers far higher volumetric efficiency than Class 1 C0G/NP0 parts but exhibits capacitance reduction under applied DC bias, aging of roughly 1-3 percent per decade hour, and piezoelectric (acoustic) behavior. For a 100 nF 0402 X7R part, expect effective capacitance to drop noticeably at bias levels approaching the 16 V rating, so verify headroom for rails near the rated voltage. Typical applications are general-purpose decoupling of microcontrollers and logic ICs, bulk bypass of small power rails, input/output filtering of DC-DC converters, and coupling or filtering in analog signal chains where Class 2 tolerance is acceptable. Design consideration: place one 0402B104K160NT directly at each IC supply pin with a short, wide trace to the ground plane; in X7R MLCCs the DC-bias derating and voltage margin are the primary trade-offs against its tiny size and low cost. This page synthesizes verified distributor pricing, drop-in alternative cross-references, and practical MLCC design notes not found in a single manufacturer datasheet.
0402B104K500CT - 0.1uF 50V X7R 0402 MLCC | Walsin
The Walsin Technology Corporation 0402B104K500CT is a multilayer ceramic capacitor (MLCC) offering 0.1 uF (100 nF) capacitance, a 50 V DC voltage rating, and +/-10% tolerance in the compact 0402 (1005 metric) surface-mount case size, using a temperature-stable X7R Class 2 dielectric. An MLCC is a passive electronic component that stores electrical charge and is built by stacking alternating layers of ceramic dielectric and metal electrodes, fired into a monolithic block with terminations on both ends. Within the passive component hierarchy, ceramic capacitors sit under capacitors, which in turn belong to the broader family of passive components. MLCCs are the most produced capacitor type worldwide, valued for small size, low ESR, and no polarity. Key features of the 0402B104K500CT include high volumetric efficiency (Walsin describes the series as delivering high capacitance in a given case size), the X7R dielectric rated from -55C to +125C with a maximum capacitance change of +/-15% over that range, and a nominal 50 V rating that provides generous margin in 3.3 V, 5 V, 12 V, and 24 V rail designs. Technically, X7R is a ferroelectric barium-titanate-based Class 2 dielectric. Its capacitance is voltage-dependent, so the effective capacitance under DC bias is lower than the nominal 0.1 uF, a factor designers must account for in decoupling budgets. Compared with C0G dielectrics, X7R offers roughly two orders of magnitude higher volumetric capacitance density, trading off precision and microphonic behavior. Typical applications include power-rail decoupling for microcontrollers and FPGAs, general-purpose bypass filtering, DC-blocking and coupling in signal chains, and bulk local energy storage on dense PCBs. The 0402 case suits high-density consumer, industrial, and IoT boards where board area is at a premium. A key design consideration is DC bias derating: at significant bias the effective capacitance can drop well below nominal, so verify effective capacitance under actual operating voltage, and place the capacitor close to the decoupled pin with short, wide traces. This page adds value beyond the manufacturer datasheet by synthesizing distributor pricing from 7 sources, drop-in cross-brand alternatives, and practical design notes such as DC-bias derating and layout guidance in one reference.
0402B104K500NT - 100nF 50V X7R 0402 MLCC | FH | Decoupling
The FH (Guangdong Fenghua Advanced Technology) 0402B104K500NT is a 100 nF (0.1 uF) multilayer ceramic chip capacitor (MLCC) rated at 50 V DC with an X7R Class 2 dielectric and a +/-10% capacitance tolerance, housed in a compact 0402 (1005 metric) surface-mount package. It is one of the most widely used decoupling capacitor values in modern PCB design. An MLCC (multilayer ceramic capacitor) is a passive component built from alternating layers of ceramic dielectric and metal electrodes, terminated at each end. Within the capacitor hierarchy, it belongs to the fixed capacitor -> ceramic capacitor -> MLCC -> chip passive family. MLCCs dominate modern electronics for decoupling, filtering, and bypassing because they are non-polarized, offer low ESR and ESL, and deliver high capacitance per volume without electrolyte degradation mechanisms. Key features of the 0402B104K500NT include its X7R temperature-stable dielectric, which holds capacitance within +/-15% across the -55C to +125C operating range; its 50 V DC rating, giving generous margin above typical 3.3 V, 5 V, and 12 V logic rails; and the 100 nF value, which provides a low-impedance path for switching transients between roughly 1 MHz and 100 MHz when paired with board inductance. The +/-10% (K) tolerance suits decoupling duty, where exact capacitance is rarely critical. The 0402 (1005 metric) footprint - 1.0 mm x 0.5 mm - is an industry-standard land pattern supported by every pick-and-place platform and most PCB assembly houses. The nickel-barrier terminated structure supports reflow soldering per standard SMT profiles. As a Class 2 dielectric, X7R exhibits DC bias and voltage-coefficient effects, so effective capacitance drops under applied DC voltage - a known trade-off versus C0G types. Typical applications include MCU and FPGA supply decoupling, power-entry bypass in DC-DC converters, general filtering in consumer and industrial boards, and fine-pitch IC local bypass where board space is at a premium. Design tip: place one 0402B104K500NT as close as possible to each power pin of the target IC, and combine it with bulk capacitance (10-100 uF) plus a smaller high-frequency capacitor to flatten the supply impedance profile.

0402B222K250CT - 2200pF 25V X7R 0402 MLCC | Walsin
The Walsin Technology Corporation 0402B222K250CT is a 2200 pF (2.2 nF) multilayer ceramic capacitor (MLCC) rated at 25 V DC with a +/-10% capacitance tolerance, an X7R Class 2 dielectric, and a 0402 (1005 metric) surface-mount package supplied on tape and reel. An MLCC is a passive capacitor built from alternating layers of ceramic dielectric and metal electrodes, terminated at opposite ends for surface mounting. Within the passive component hierarchy, it belongs to the ceramic capacitor family, itself a subset of fixed capacitors. X7R is a temperature-stable Class 2 dielectric defined as maintaining capacitance within +/-15% over the -55C to +125C temperature range, making it the workhorse dielectric for decoupling, bypass, and filtering where moderate stability is sufficient. Key features of the 0402B222K250CT include the X7R dielectric for temperature stability up to 125C, a 25 V DC voltage rating suitable for 3.3 V, 5 V, and 12 V logic rails with margin, the compact 0402 (1.0 mm x 0.5 mm) footprint that supports high-density PCB layouts, and +/-10% K tolerance for predictable circuit behavior. The nickel-barrier termination is compatible with reflow and wave soldering profiles per standard SMT assembly processes. The multilayer construction stacks thin dielectric layers with sintered nickel and copper or silver terminations, yielding high capacitance per unit volume and low equivalent series inductance compared with through-hole alternatives. X7R capacitance varies with applied DC bias, so designers should derate expected effective capacitance at operating voltage in timing or filter circuits. Typical applications include power-supply decoupling for microcontrollers and FPGAs, input and output filtering on DC-DC converters, analog signal coupling and bypass, and general-purpose RC networks in consumer, industrial, and automotive-adjacent electronics. The 2.2 nF value is common in snubber and EMI filter positions. Design consideration: X7R components exhibit piezoelectric (acoustic) effects and DC-bias capacitance loss; for precision timing, prefer C0G dielectric. Keep traces short to minimize parasitic inductance at decoupling sites.

0402CG330J500NT - 33pF 50V C0G 0402 MLCC | FH | Decoupling & RF
The Fenghua 0402CG330J500NT is a 33 pF multilayer ceramic chip capacitor (MLCC) rated at 50 V DC with a C0G (NP0) Class I dielectric and a ±5% (J) tolerance, packaged in the industry-standard 0402 (1005 metric) surface-mount footprint. A multilayer ceramic capacitor is a passive component that stores charge in a ceramic dielectric between alternating metal electrode layers. Within the capacitor hierarchy, MLCCs sit in the broad family of fixed capacitors, and the C0G dielectric class defines the most stable subgroup: it exhibits essentially no capacitance change with temperature (0 +/- 30 ppm/C), negligible aging, and low dielectric loss, unlike Class II X7R or X5R parts that trade stability for higher volumetric density. Key features of this part include the tight ±5% tolerance for predictable timing and filter behavior, the ultra-stable C0G dielectric suitable for resonant and RF circuits, a 50 V rating compatible with most low-voltage digital and analog rails, and operation up to 125 C per the FindIC-listed specification line (Cap Ceramic 33pF 50V C0G 5% SMD 0402 125C, paper Tape & Reel packaging). Because C0G ceramics have near-zero voltage coefficient and very low ESR, this 33 pF value is typically used for crystal load capacitance, RF matching networks, high-frequency filtering, and precision timing where capacitance drift would shift circuit behavior. The 33 pF value is especially common as the load capacitor pair for 32.768 kHz crystals and MHz-range quartz resonators. Typical applications include crystal oscillator circuits in microcontroller systems, RF front-end matching in wireless modules, precision analog filters in instrumentation, and high-speed digital decoupling where stable low-value bypass capacitance is required. Design consideration: for crystal load applications, remember that each capacitor contributes C_stray plus C_load/2 - factor in PCB parasitics (typically 2-5 pF) when selecting between 33 pF and neighboring values.

0402X105K100CT - 1uF 10V X5R 0402 MLCC | Walsin | Decoupling
The Walsin Technology Corporation 0402X105K100CT is a 1 uF multilayer ceramic chip capacitor (MLCC) rated at 10 V DC with a X5R Class 2 dielectric and a tolerance of +/-10%, packaged in the industry-standard 0402 (1005 metric) surface-mount case size. An MLCC is a passive electronic component built from alternating layers of ceramic dielectric material and metal electrodes, fired together into a monolithic block with termination electrodes on both ends. As part of the capacitor family within the broader passive components hierarchy, MLCCs store charge, filter noise, and stabilize supply rails, and they are the most widely deployed passive device on modern PCBs due to their small size, low ESR, and lack of polarity. Key features of the 0402X105K100CT include a high volumetric efficiency of 1 uF in the 0402 (1005 metric) outline, the X5R dielectric specification (-55C to +85C operating range, +/-15% capacitance change over temperature), and a tight +/-10% capacitance tolerance (K code). The CT suffix denotes tape-and-reel packaging suitable for automated pick-and-place assembly. The X5R ferroelectric dielectric provides substantially higher permittivity than Class 1 dielectrics such as C0G, enabling large capacitance in a tiny footprint, at the cost of voltage-dependent capacitance (DC bias derating) and moderate temperature stability. Designers must account for effective capacitance derating under DC bias when relying on this part for decoupling. Typical applications include general-purpose power-supply decoupling at microcontroller and FPGA supply pins, input and output filtering for DC-DC converter modules, and bulk capacitive buffering in portable, IoT, and consumer electronics where board area is at a premium. A key design consideration is DC bias derating: X5R devices in small case sizes can lose 30-50% of rated capacitance at a significant fraction of rated voltage, so verify effective capacitance under the actual operating voltage rather than nominal value. This page synthesizes distributor pricing, cross-referenced drop-in alternatives from multiple manufacturers, and practical design notes not found in the manufacturer datasheet alone.
0402X475M6R3CT - 4.7uF 6.3V X5R 0402 MLCC | Walsin
The Walsin Technology Corporation 0402X475M6R3CT is a 4.7 uF multilayer ceramic capacitor (MLCC) rated at 6.3 V DC with a +/-20% tolerance and X5R dielectric, housed in a compact 0402 (1005 metric) surface-mount case size. An MLCC is a passive component that stores electrical charge using alternating layers of ceramic dielectric and metal electrodes. Within the passive component hierarchy, it belongs to the capacitor family, alongside tantalum, aluminum electrolytic, and film capacitors. MLCCs are the most widely deployed capacitors in modern electronics because they combine small size, low ESR, and high reliability, making them the default choice for decoupling and bypass roles in power distribution networks. Key features of the 0402X475M6R3CT include a very high 4.7 uF capacitance density for a 0402 package, an X5R Class II dielectric delivering +/-15% capacitance change over -55C to +85C, and a 6.3 V DC rating suitable for low-voltage digital and analog rails. The +/-20% tolerance accommodates the typical DC-bias derating behavior of ferroelectric dielectrics. Surface-mount termination supports standard reflow soldering profiles per common SMT assembly processes. Technically, the X5R dielectric offers high volumetric efficiency but with capacitance that drops under DC bias and at low temperature, so designers should verify effective capacitance at operating conditions. Being non-polarized, the part can be mounted in either orientation, and its low ESR supports fast transient response in decoupling applications where electrolytic capacitors would be too slow or too large. Typical applications include power supply decoupling for microcontrollers and SoCs, DC-DC converter input and output filtering, smartphone and tablet power rails where board space is scarce, and general bypass functions on 1.8 V to 5 V rails. A key design consideration: at 6.3 V rating, do not apply more than 6.3 V DC, and account for DC-bias derating which can reduce effective capacitance by 30-50% at rated voltage on X5R MLCCs; consider a 10 V-rated variant for margin. This page adds information gain beyond the manufacturer datasheet by synthesizing distributor pricing from five sources, drop-in alternatives from Murata, KELTRON... rather, KEMET and Murata, and practical MLCC design notes in one reference.
0402YD105KAT2A - 1uF 16V X5R 0402 MLCC | KYOCERA AVX
The KYOCERA AVX 0402YD105KAT2A is a 1 uF multilayer ceramic capacitor (MLCC) rated at 16 V DC with a X5R dielectric and a +/-10% tolerance, packaged in a compact 0402 (1005 metric) surface-mount case. It is part of the AVX AMK/0402Y commercial-grade MLCC series intended for general decoupling, filtering, and DC-link energy storage in dense PCB designs. An MLCC (multilayer ceramic capacitor) is a passive electronic component built from alternating layers of ceramic dielectric and metal electrodes, sintered into a monolithic block with terminations on both ends. Within the passive-component hierarchy, it sits under capacitor > ceramic capacitor > multilayer ceramic chip capacitor, and it is the dominant decoupling element in modern surface-mount electronics because of its small size, low ESR, and absence of polarity. Key features of the 0402YD105KAT2A include its high volumetric efficiency - 1 uF in a 1.0 x 0.5 mm footprint - the temperature-stable X5R formulation rated -55 C to +85 C with up to +/-15% capacitance change over that range, and a 16 V DC working voltage with a K-code (10%) tolerance for predictable decoupling impedance. Nickel-barrier terminations support reflow and wave soldering. Architecturally, the part uses a thin-layer high-K barium-titanate-based X5R ceramic stack. X5R delivers far higher permittivity than Class I dielectrics (C0G/NP0), enabling microfarad-range capacitance in tiny cases, at the cost of DC-bias and voltage-coefficient effects that engineers must account for in power-rail design. Typical applications include power-supply decoupling for MCUs, FPGAs, and PMICs, output and input filtering in DC-DC converters, RF-module supply bypassing, and general bypass duties in consumer, industrial, and IoT hardware where board space is constrained. A critical design consideration: X5R capacitance derates significantly under DC bias - verify effective capacitance at your actual operating voltage rather than using the nominal 1 uF value. This page adds value beyond the datasheet by combining verified distributor pricing, drop-in alternative cross-references, and practical X5R derating design notes in one place.
06031C103K4T2A - 10nF 100V X7R 0603 MLCC | KYOCERA AVX
The KYOCERA AVX 06031C103K4T2A is a 10000 pF (10 nF) multilayer ceramic capacitor (MLCC) with a 100V DC voltage rating, a +/-10% tolerance, and an X7R Class II dielectric, housed in a surface-mount 0603 (1608 metric) chip package. An MLCC is a passive component built from alternating layers of ceramic dielectric and metal electrodes, terminated on two opposing ends for surface-mount soldering. MLCCs are the most widely deployed capacitor family in modern electronics, spanning the hierarchy from decoupling capacitor to bypass capacitor to general-purpose voltage regulator support component, and they sit at the foundation of nearly every power-management and signal-integrity design. Key features of the 06031C103K4T2A include the temperature-stable X7R dielectric, which holds capacitance within +/-15% over the -55C to +125C industrial temperature range, and the 100V rating that provides generous headroom for 12V, 24V, and 48V rail decoupling. The K tolerance code guarantees +/-10% capacitance accuracy, and the T2A suffix denotes 7-inch reel taping for automated pick-and-place assembly with matte-tin nickel-barrier terminations compatible with reflow soldering and lead-free (RoHS) processes. Technically, X7R is an EIA Class II barium-titanate-based formulation offering intermediate dielectric constant with predictable, modest voltage-coefficient and aging behavior (approximately 1-2% per decade-hour aging). Compared with Class I C0G/NP0 parts, X7R delivers far higher volumetric efficiency, making it the default choice for decoupling, filtering, and coupling where exact capacitance precision is not critical. Typical applications include decoupling of microcontroller and FPGA power rails, snubber and filtering networks in industrial power supplies, bypass capacitors in automotive and telecom control boards, and general coupling in instrumentation operating over wide temperature extremes. When designing with this part, remember that X7R capacitance derates with applied DC bias; verify effective capacitance at your operating voltage rather than relying on the nominal 10 nF. This page synthesizes distributor pricing, verified drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving procurement and engineering teams a single decision-ready reference.
06033W106MAT2A - 10uF 25V X6S MLCC 0603 | KYOCERA AVX
The KYOCERA AVX 06033W106MAT2A is a 10 uF multilayer ceramic chip capacitor (MLCC) rated at 25 V DC with a ±20% capacitance tolerance, built in the compact 0603 (1608 metric) surface-mount package measuring 1.60 mm x 0.80 mm. It uses the X6S Class II dielectric, which specifies stable operation from -55°C to +105°C. An MLCC (multilayer ceramic capacitor) is a passive component that stores charge in a ceramic dielectric between alternating metal electrode layers. MLCCs sit within the broader capacitor family alongside film, tantalum, and aluminum electrolytic types, and they dominate modern decoupling and bypass roles because they are non-polar, miniature, and offer very low equivalent series resistance (ESR) and equivalent series inductance (ESL). Key features of the 06033W106MAT2A include its exceptionally high 10 uF capacitance in a 0603 case, a size class traditionally limited to 1-4.7 uF. This is achieved through high-K X6S ceramic formulation and thin dielectric layers. The 25 V rating covers 24 V industrial rails with margin, and the -55°C to +105°C X6S temperature range with relatively flat capacitance versus temperature makes it suitable for automotive-adjacent and industrial environments. Technically, the 3W dielectric code corresponds to AVX's X6S formulation. As with all Class II dielectrics, capacitance decreases with applied DC bias and with aging; designers should expect meaningful derating of the nominal 10 uF at substantial DC bias and should verify effective capacitance in simulation or bench measurement. The MAT2A suffix denotes the termination and packaging variant per AVX numbering. Typical applications include power supply decoupling for microcontrollers, FPGAs, and gate-driver ICs, output filtering of DC-DC converters, and bulk capacitance in space-constrained portable and industrial designs where a 0805 or 1206 tantalum would previously have been used. A key design consideration is DC bias derating: like all high-K MLCCs, effective capacitance can fall substantially at voltages approaching the rating, so allocate margin and consult the manufacturer's bias curves. Piezoelectric acoustic noise in Class II MLCCs may also matter in sensitive analog circuits. This page synthesizes distributor availability data, drop-in alternatives, pricing tiers, and practical design notes not found in the manufacturer datasheet, giving engineers a complete sourcing and design resource for the 06033W106MAT2A.
06035A8R0C4T2A - 8pF 50V C0G 0603 MLCC | KYOCERA AVX
The KYOCERA AVX 06035A8R0C4T2A is an 8 pF multilayer ceramic capacitor (MLCC) with a C0G (NP0) temperature-stable dielectric, rated at 50 V DC, with a tight capacitance tolerance of plus or minus 0.25 pF, housed in a surface-mount 0603 (1608 metric) package. It is supplied on tape and reel for automated pick-and-place assembly. A multilayer ceramic capacitor is a passive component that stores electrical charge using multiple alternating layers of ceramic dielectric and metal electrodes. Within the passive component hierarchy, MLCCs sit under capacitors, which in turn belong to the broader class of passive electronic components. The C0G dielectric class, also known as NP0 (negative-positive zero), belongs to Class I ceramic materials defined by near-zero temperature coefficient and negligible capacitance drift with voltage, time, and aging, unlike Class II dielectrics such as X7R or X5R. Key features of the 06035A8R0C4T2A include the ultra-stable C0G dielectric, which delivers minimal capacitance variation across the operating temperature range, and the tight plus or minus 0.25 pF tolerance, which is essential where predictable reactance matters, such as resonant tank circuits and crystal oscillator loading. The 50 V rating provides generous margin over typical 3.3 V and 5 V logic rails. Technically, C0G MLCCs exhibit low dielectric absorption, low dissipation factor, and stable equivalent series resistance, making them suitable for high-frequency and precision analog signal paths. The small 0603 footprint (approximately 1.6 mm by 0.8 mm) supports dense PCB layouts while keeping parasitic inductance low. Typical applications include crystal load capacitance in microcontroller oscillators, RF matching networks and filters, precision timing circuits, analog signal coupling, and high-frequency bypassing where Class II dielectrics would introduce microphonic or voltage-coefficient errors. A key design consideration is PCB pad geometry: follow IPC-recommended 0603 land patterns to control solder fillet height, and avoid excessive reflow peak temperatures that can stress the termination. Sensitivity to board flex should also be considered in thick-board or connector-adjacent placements.

125 - Cornell Dubilier Long-Life High-Temp Capacitor | CDE
The Cornell Dubilier Electronics 125 is an aluminum electrolytic capacitor marketed as the Pace-Setter for Long Life and High Temperature applications, supplied in a through-hole/axial-style package rated for elevated thermal stress. According to the verified Alldatasheet record (5-page PDF, 805 Kb), this part belongs to Cornell Dubilier's classic Type 125 series, a heritage line of long-life aluminum electrolytic capacitors used where reliability under high ambient temperature and continuous ripple current is required. Its headline characteristics include extended operational life (often 5000 h to 10000 h at rated temperature), wide capacitance range options, and a polar axial termination suitable for PCB through-hole insertion or chassis mounting. An aluminum electrolytic capacitor is a polarized passive component that uses an etched aluminum foil anode, a paper spacer soaked in electrolyte, and a cathode foil to form a high-capacitance energy storage element. The oxide dielectric layer on the anode, formed electrochemically during manufacturing, allows volumetric efficiencies far higher than ceramic or film capacitors. Within the broader passive taxonomy, the 125 sits in the hierarchy: aluminum electrolytic capacitor -> electrolytic capacitor -> capacitor -> passive component, and is typically categorized for power supply filtering, bulk energy storage, and decoupling on industrial and audio electronics. Key features of the Cornell Dubilier 125 series include high-temperature endurance commonly rated up to 125 °C with derated voltage, low equivalent series resistance (ESR) variants, and non-solid, wet-electrolyte construction that self-heals under voltage stress. The axial-lead package simplifies insertion into chassis-mounted assemblies and tight PCB layouts where radial parts would not fit. Typical applications include switch-mode power supply output filtering after the rectifier, bulk capacitance on DC bus rails in motor drives, audio amplifier power supply bypass networks, and energy storage in industrial control power supplies. The 125's high-temperature rating also suits under-hood automotive subsystems and welding inverter bulk filtering. A key design consideration when using the Type 125 is ensuring ripple current stays below the rated value at the operating temperature; lifetime is approximately halved for every 10 °C rise above rated. Always confirm exact voltage, capacitance, and case dimensions from the manufacturer datasheet before PCB layout. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on the standalone manufacturer datasheet, giving engineers a single reference for the Cornell Dubilier 125 series.
16CE680AX - 680uF 16V SMD Aluminum Electrolytic Capacitor | SUNCON
The SUNCON (SUN Electronic Industries) 16CE680AX is a 680 microfarad polarized surface-mount aluminum electrolytic capacitor rated at 16 V DC working voltage, supplied in the CE-AX Series SMD package. It features a ±20% capacitance tolerance, a maximum allowable ripple current of 109 microamperes leakage rating, and RoHS-compliant lead-free construction suited to automated reflow assembly lines. An aluminum electrolytic capacitor is a polarized passive component that uses an etched aluminum foil anode, a conductive electrolyte, and an oxide dielectric film to store charge at high volumetric efficiency. Aluminum electrolytic capacitors sit within the broader taxonomy of capacitors -> passive components -> electronic components, and SMD (surface-mount device) variants such as the CE-AX series replace through-hole parts on high-density printed circuit boards. They offer very high capacitance per unit cost but have higher equivalent series resistance (ESR) and shorter operational life than ceramic or film capacitors. Key performance characteristics include a category operating temperature range of -55 °C to +105 °C, an endurance rating of 2000 hours at +105 °C for case diameters phi 8 mm through phi 16 mm (and 1000 hours for phi 4 to phi 6.3 mm and phi 10x7.7 mm case sizes), and a stable post-endurance capacitance shift within ±25% of the initial measured value. The capacitor integrates a pressure relief vent for case diameters greater than phi 8 mm, providing safety against catastrophic failure under severe overvoltage or reverse-bias conditions. Typical applications include bulk decoupling on DC-DC converter input rails, output smoothing for low-frequency switching power supplies, energy-storage reservoirs in audio amplifiers, and bypass capacitance on industrial control boards. The CE-AX SMD footprint supports high-volume pick-and-place assembly, making the part attractive for cost-sensitive consumer electronics where high capacitance density in a small case is required. When designing with the 16CE680AX, observe polarity strictly to avoid reverse-bias failure and ensure reflow peak temperature does not exceed the datasheet-specified profile. For long-life applications above 1 A of ripple current, derate temperature or consider paralleling multiple units to reduce thermal stress and extend operational life.

16SVPC270M - 270µF 16V OS-CON Polymer Capacitor | Panasonic
The Panasonic 16SVPC270M is a 270µF / 16V conductive polymer aluminum solid capacitor (OS-CON SVPC series) housed in a radial-can SMD package measuring 8mm × 11.9mm. It delivers an industry-low equivalent series resistance of 16mΩ and supports a maximum ripple current of 4070mA, making it one of the highest-current-density polymer capacitors in the 16V / 270µF class. An OS-CON (Organic SemiConductive CONductive polymer) capacitor is a type of aluminum solid electrolytic capacitor in which the liquid electrolyte is replaced by a conductive polymer. Compared with conventional aluminum electrolytic capacitors, OS-CON parts offer much lower ESR, lower impedance at high frequency, better temperature stability, and far longer operational life. They sit between multilayer ceramic capacitors (MLCCs) and tantalum capacitors in the performance hierarchy, offering high capacitance with very low parasitic loss. Key features of the 16SVPC270M include ±20% capacitance tolerance, 2000-hour endurance at 105°C, RoHS compliance, and halogen-free construction. The 16mΩ ESR is the headline differentiator: at 100kHz the impedance approaches 8mΩ, which is roughly an order of magnitude lower than a comparably-rated wet aluminum electrolytic. This allows the part to suppress high-frequency noise on DC rails far more effectively than legacy aluminum or polymer-tantalum alternatives of the same voltage class. Technically, the 16SVPC270M uses a sintered aluminum anode with a conductive polymer (typically PEDOT) cathode formed by in-situ polymerization. The polymer electrolyte gives the capacitor non-polar behavior under surge, ultra-low self-heating under ripple, and a benign failure mode (open-circuit rather than short-circuit). Operating temperature range spans -55°C to +105°C, with derating required above 105°C for continuous full-rated-ripple operation. Typical applications include point-of-load (POL) bypass for CPUs/ASICs/FPGAs, post-DC/DC output filtering in telecom and networking hardware, decoupling for graphics cards and high-current ASICs, automotive infotainment power rails, and server/SSD bulk hold-up. Designers choose the 16SVPC270M where MLCCs cannot provide enough bulk capacitance (and where vibration-sensitive ceramic cracking is a concern) or where wet aluminum electrolytics fail to meet ESR/ripple targets. Design considerations include verifying that the PCB land pattern matches the 8×11.9mm radial-can footprint, providing adequate copper pad area for heat spreading, and ensuring that ripple current does not exceed 4070mA at the operating temperature after derating. Compared with larger wet aluminum capacitors the 16SVPC270M offers 10× longer life and 5–10× lower ESR in the same voltage class. This page synthesizes distributor pricing, drop-in polymer-alternative references, and practical decoupling guidance that the manufacturer datasheet alone does not surface.
25ZLH1000MEFC10X23 - 1000µF 25V Low-Impedance Radial Electrolytic | Rubycon
The Rubycon 25ZLH1000MEFC10X23 is a 1000 µF, 25 V radial-leaded aluminum electrolytic capacitor from Rubycon's ZLH series, housed in a 10 mm × 23 mm can with 5 mm lead pitch and a PET insulating sleeve. It is specified for 10000 hours of load life at 105 °C and a maximum ripple current of 2250 mA at 105 °C and 100 kHz, giving it low-impedance behavior suited to switching power supply output filtering. An aluminum electrolytic capacitor is a polarized passive component that uses an etched aluminum anode foil, a paper separator saturated with electrolyte, and a cathode foil to form a non-solid electrolytic dielectric. The ZLH series specifically targets low-impedance, high-ripple-current applications such as switch-mode power supply (SMPS) output filters, DC-DC converter input/output reservoirs, and audio amplifier power-rail bypass. In the broader taxonomy, electrolytic capacitors sit below ceramic, film, and tantalum within the capacitor family, and the ZLH series competes with Nichicon HE and Panasonic FR-series parts in the same 10×23 mm footprint. Key features include a ±20 % capacitance tolerance at 120 Hz / 20 °C, a 25 V rated DC working voltage with substantial de-rating headroom to 35 V surge, and an impedance specification that drops by a factor of roughly two to four relative to the older ZL series at 100 kHz. The ZLH series also offers a 1.0 µA maximum leakage current after 2 minutes at 25 °C, which is competitive within its voltage class. Endurance is 10000 hours @ 105 °C with rated voltage and ripple current applied. Typical applications include the output filter capacitor following a 12 V to 5 V buck converter in industrial equipment, where its 2250 mA ripple rating and 10×23 mm footprint absorb the switching ripple without overheating. It is also commonly used as a bulk reservoir capacitor on the input side of multi-rail supplies and in audio amplifier power sections. When designing with this part, ensure that the ripple current does not exceed 2250 mA at 100 kHz and 105 °C ambient, and that the lead spacing (5 mm) matches the PCB pad layout.
293D106X9016B2TE3 - 10uF 16V Solid Tantalum Capacitor | Vishay
The Vishay Sprague 293D106X9016B2TE3 is a 10 uF, 16 V molded solid tantalum surface-mount chip capacitor with ±10% tolerance and 2 ohm maximum ESR, packaged in the industry-standard B case (1411 / 3528 metric, 3.5 x 2.8 x 1.9 mm). A solid tantalum capacitor is a polarized capacitor that uses tantalum metal as the anode with a manganese dioxide solid electrolyte, rather than a liquid electrolyte. Within the passive-component hierarchy, it sits under capacitors -> fixed capacitors -> electrolytic capacitors -> tantalum capacitors. Tantalum technology is preferred where volumetric efficiency (high capacitance per unit volume), stable electrical parameters over life, and low aging rates are required. Key features of this TANTAMOUNT molded-case device include stable capacitance over temperature and life, a rated voltage of 16 V DC at +85 C (derated to +125 C), ±10% tolerance, and a 2 ohm ESR in a molded case that provides mechanical robustness and superior moisture resistance versus uncoated chips. The TE3 suffix denotes lead-free, RoHS-compliant construction in tape-and-reel packaging for automated pick-and-place assembly. Technically, the 293D series uses solid manganese dioxide cathode construction, which eliminates dry-out failure mechanisms common in aluminum electrolytics. Capacitance for the family spans 0.1 uF to 1000 uF, and this B-case variant balances capacitance density with a moderate ESR suited to general-purpose decoupling and filtering. Reverse-voltage capability is limited, so correct polarity must be maintained on the PCB. Typical applications include industrial control power-supply decoupling, telecom equipment DC filtering, portable and battery-powered device bulk storage, and general-purpose output filtering on DC-DC converters, where stable parameters and compact size matter. A key design consideration is voltage derating: industry practice recommends operating solid tantalum capacitors at 50% or less of rated voltage on high-impedance or ripple-current-prone rails, so the 16 V rating is best applied at 8 V or lower.

293D107X9010D2TE3 - 100µF 10V Tantalum Capacitor D-Case | Vishay
The Vishay Sprague 293D107X9010D2TE3 is a solid tantalum surface-mount chip capacitor rated at 100 µF with a 10 V DC working voltage, 10% capacitance tolerance, and 0.6 ohm equivalent series resistance (ESR), packaged in the industry-standard 2917 (7343 Metric) D-case measuring 7.3 mm x 4.3 mm x 2.8 mm. Part of the TANTAMOUNT® 293D industrial-grade family, the device uses a molded tantalum pentoxide dielectric with 100% matte tin terminations, delivering stable electrical parameters and long service life in demanding applications. The part is supplied on 7-inch tape and reel per EIA 481, with the anode (+) marked by a polarity bar. A solid tantalum capacitor is a polarized surface-mount capacitor that uses sintered tantalum powder as the anode and a manganese dioxide or polymer cathode to achieve high volumetric capacitance density. Compared to aluminum electrolytic capacitors, tantalum parts deliver higher capacitance per unit volume, lower ESR, no dry-out failure mode, and superior frequency stability, making them the preferred choice for bulk decoupling and point-of-load filtering in switching power supplies, DC-DC converters, and analog circuits where reliability and small PCB footprint are required. The hypernym hierarchy is: tantalum capacitor -> electrolytic capacitor -> polarized capacitor -> capacitor -> passive component. Key specifications include a 100 µF nominal capacitance with ±10% tolerance (per the "107" and "10%" codes in the part number), 10 V rated DC working voltage (per the "10" code), 0.6 ohm maximum ESR at 100 kHz / +25 °C, an operating temperature range of -55 °C to +85 °C (with voltage derating required above +85 °C up to +125 °C), and a maximum ripple current rating suitable for switch-mode power supply output filtering. The molded epoxy body provides mechanical robustness and supports automated pick-and-place assembly. From an applications perspective, the 293D107X9010D2TE3 is commonly used as a bulk output capacitor on the secondary side of DC-DC converters (buck, boost, and SEPIC topologies), as a bypass/decoupling element next to FPGAs, ASICs, and microcontrollers, in point-of-load regulators downstream of intermediate bus voltages, in industrial control and instrumentation, and in automotive non-safety electronics where commercial-grade reliability is sufficient. The part meets IEC specification QC300801/US0001 and EIA 535BAAC standard requirements. When designing with this part, observe the rated voltage derating guidelines recommended by Vishay for tantalum capacitors (typically 50% or less of rated voltage for reliability) and respect polarity during board layout and assembly. Reverse bias, even well below a ratings threshold, can cause dielectric breakdown and catastrophic failure. ESR at the switching frequency of the surrounding converter should be verified to ensure adequate ripple handling.

293D476X9010D2T - 47µF 10V Molded Tantalum Capacitor D-Case | Vishay
The Vishay 293D476X9010D2T is a solid, molded surface-mount tantalum capacitor with a rated capacitance of 47 µF and a 10 V DC working voltage in the EIA 7343 (D-case) footprint. It belongs to the well-established Vishay Sprague 293D series, which is widely used as a general-purpose bulk-decoupling and filtering capacitor in commercial and industrial designs. The 293D476X9010D2T carries a ±10% capacitance tolerance (the X9 digit in the Vishay ordering code) and a 10% maximum dissipation-factor specification typical of the 293D family. A solid tantalum electrolytic capacitor is a polarized component that uses a sintered tantalum pellet and a manganese-dioxide or polymer cathode to deliver high volumetric efficiency in surface-mount packages. Compared with aluminum electrolytics, tantalum capacitors offer lower ESR, no dry-out risk, and stable capacitance over time, making them a preferred choice for point-of-load bypassing, hold-up energy storage, and analog signal-chain filtering where reliability and stable parameters across the operating lifetime are critical. Key features of the 293D476X9010D2T include the molded plastic epoxy body that protects the tantalum element from mechanical stress and provides a flat top surface for reliable vacuum-pick-and-place assembly. The D-case (7343 metric) measures approximately 7.3 mm × 4.3 mm × 2.8 mm, suiting standard reflow profiles. The capacitor is supplied on 7-inch reels for automated assembly, with an embossed carrier-pocket standard for 12 mm tape per EIA 481. The 293D476X9010D2T is commonly used in industrial controllers, automotive body electronics, telecom infrastructure, and consumer devices for output filtering on switch-mode power supplies, local decoupling of high-current digital ICs, and timing-circuit energy storage. Designers value the 293D series for its predictable surge-current handling and for compatibility with the standard surface-mount reflow process used in modern SMT lines. When laying out the PCB, observe the standard D-case land pattern recommended in the Vishay datasheet, respect the polarity stripe, and never apply reverse DC bias.
2TPSF270M9G - 270µF 2V 9mΩ POSCAP Polymer Tantalum | 1411
Panasonic 2TPSF270M9G is a 270 µF / 2 V molded conductive-polymer tantalum solid capacitor (POSCAP TPSF series) with super-low ESR of 9 mΩ at 100 kHz, housed in the compact 1411 (3528 metric, 3.5 × 2.8 × 1.9 mm) face-down terminal SMD case. Designed as a Case B2S POSCAP, it combines very low ESR, very low ESL (≤ 0.7 nH), 20 % capacitance tolerance, and a maximum operating temperature of 105 °C. According to the manufacturer datasheet, ESR is rated at 9 mΩ at 100 kHz with a dissipation factor of 1.5× the initial limit and capacitance change kept within the initial-limit spec, making it suitable for high-frequency DC-bus filtering where MLCCs alone cannot deliver the bulk µF needed. A POSCAP (Polymer Tantalum Solid Capacitor) is a solid-state capacitor that uses a conductive polymer cathode instead of a wet or MnO2 electrolyte. POSCAP belongs to the polymer capacitor hierarchy: polymer capacitor → solid tantalum capacitor → tantalum capacitor → electrolytic-style capacitor family. Compared with MnO2 tantalum, POSCAP offers lower ESR, benign failure mode (no thermal runaway), and superior high-frequency impedance, at the cost of lower maximum voltage (typically ≤ 35 V). POSCAPs are widely used as output bulk capacitors on point-of-load (POL) converters and as decoupling capacitors near FPGAs, ASICs, and high-speed SerDes. Key features include 270 µF nominal capacitance at 2 V rated voltage, 9 mΩ ESR at 100 kHz, ≤ 0.7 nH ESL, RoHS compliance, halogen-free construction, and a face-down terminal layout that minimizes the current loop between the capacitor and the IC. The B2S case footprint (3.5 × 2.8 × 1.9 mm) provides mechanical robustness while keeping the PCB area under 10 mm², and the tape-and-reel packaging supports high-speed SMT assembly. The 2TPSF270M9G is engineered for low-impedance, high-transient-current applications where conventional MLCCs would require many parallel devices. The polymer cathode's very low ESR flattens the impedance curve at high frequencies, while the solid construction eliminates the dry-out and acoustic-noise issues of ceramic or electrolytic capacitors. With 9 mΩ ESR, ripple-current capability per derating is high for its case size, enabling reliable operation adjacent to multi-amp switching regulators. Typical applications include CPU/GPU POL output filtering, FPGA/ASIC core-rail decoupling, server and DC-DC point-of-load bulk hold-up, USB-PD and quick-charge adapter output smoothing, and graphics-card memory-rail bypass. The 2 V rating aligns naturally with 1.0–1.8 V core rails produced by step-down converters with 3.3 V or 5 V inputs. When designing with this part, derate the applied voltage to ≤ 70 % (≤ 1.4 V for a 2 V part) in low-impedance circuits to ensure long-term reliability. Use wide, short copper pours between the POSCAP pads and the load to minimize trace inductance, and pair with 0.1 µF / 1 µF MLCCs to cover the high-frequency notch above the POSCAP self-resonant frequency.

35TQS47MEU - 47uF 35V POSCAP Tantalum Polymer | Panasonic
The Panasonic 35TQS47MEU is a 47 microfarad molded conductive polymer tantalum solid capacitor (POSCAP) rated at 35 V DC in the 2917 (7343 metric) case size, with 100 mOhms equivalent series resistance measured at 100 kHz. Housed in a surface-mount molded package measuring 7.3 mm x 4.3 mm x 2.8 mm, this POSCAP delivers a maximum allowable ripple current of 1200 mA and supports operation across the standard -55C to +105C automotive and industrial range. Conductive polymer tantalum solid capacitors (POSCAP) are a subset of the tantalum capacitor family in which the conventional manganese dioxide cathode is replaced by a conductive polymer layer. This polymer cathode lowers equivalent series resistance (ESR), eliminates the risk of ignition failure mode common to MnO2 tantalum, and provides stable capacitance and dissipation factor across frequency and temperature. POSCAP therefore sits between multi-layer ceramic capacitors (MLCC) and aluminum polymer capacitors in the decoupling and bulk-hold-up hierarchy used on modern DC/DC converter outputs. Key features of the 35TQS47MEU include 20% capacitance tolerance, a category temperature range of -55C to +105C, and full RoHS compliance with halogen-free construction. The device is lead-free reflow compatible per JEDEC J-STD-020 and ships in embossed carrier tape on 180 mm or 330 mm reels. The 2917 (7343) case provides a low-profile footprint suitable for point-of-load regulators, graphics card POL outputs, and server VRM hold-up capacitors where 35 V working voltage headroom is required. The TQS series uses an internal polymer cathode that is burned in during the factory formation step, providing both low ESR and a benign failure mode (the part simply increases ESR rather than igniting under voltage stress). This makes the 35TQS47MEU well suited as a bulk output capacitor on 24 V industrial buses, 28 V automotive rails, and 12 V adapter-derived rails where traditional MnO2 tantalum would be marginal. Typical applications for the 35TQS47MEU include point-of-load bulk decoupling on 24 V industrial systems, hold-up capacitance on 12 V and 19 V adapter rails, output smoothing for buck converters powering FPGAs and ASICs, audio amplifier power supply bypass, and SSD/HDD motor drive bulk filtering. The 35 V rating provides at least 30% derating headroom over a nominal 24 V input, extending operational life. When designing with this POSCAP, observe the 35 V absolute maximum DC rating and provide 20-30% voltage derating for reliability. Place the capacitor as close as possible to the load or DC/DC output node to minimize parasitic inductance. The polymer cathode has a self-healing characteristic under voltage surge, but reversed polarity must still be avoided.

AL213639229E3 - 22µF 100V Aluminum Electrolytic Capacitor | Vishay
The Vishay AL213639229E3 is a 22µF 100V radial aluminum electrolytic capacitor from the MAL2136 series, designed for high-reliability power supply applications. Housed in a radial-lead cylindrical aluminum case with a blue PET insulating sleeve and pressure relief vent, this polarized part delivers a useful life of 4000 hours at +105°C and supports a low impedance, low ESR profile optimized for switched-mode power supply (SMPS) and DC/DC converter use. An aluminum electrolytic capacitor (Al e-cap) is a polarized passive component that uses an anodized aluminum oxide dielectric layer and a non-solid electrolyte to store charge. Al e-caps occupy the entry-level tier of the electrolytic capacitor family, sit below tantalum and polymer capacitors in the dielectric-quality hierarchy, and dominate bulk energy storage and decoupling roles in power management, motor drive, and audio circuits where cost-per-microfarad matters more than absolute precision. Key specifications of the AL213639229E3 include 22µF nominal capacitance (20% tolerance), 100V DC rated voltage, 4000 hours rated life at 105°C, low impedance / low ESR, and excellent ripple current capability. The device is charge- and discharge-proof, and its insulated radial leads simplify through-hole PCB insertion and wave soldering. Operating temperature range spans -40°C to +105°C. Internally the device combines a high-purity aluminum foil anode with a manganese-oxide non-solid electrolyte and a cathode foil separated by separator paper wound into a cylindrical jelly-roll. The pressure relief vent in the base prevents catastrophic failure under reverse-bias, over-voltage, or end-of-life conditions, an essential safety feature for service engineers. Typical applications for the AL213639229E3 include SMPS output filtering, DC/DC converter input/output smoothing, industrial inverter bus filtering, audio amplifier power supply bypassing, motor driver energy reservoirs, and general-purpose bulk decoupling on 48V-100V rails. It pairs naturally with the MAL2136 family siblings for higher-voltage or higher-capacitance rails. Designers should pay attention to the polarity marking on the sleeve and observe the recommended ripple current derating above 60°C ambient. For designs exceeding 4000 hours at +105°C, consider the larger-case 10,000-hour variants of the MAL2136 family, which share the same series heritage and reliability profile.
