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). This page synthesizes distributor pricing context, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
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. This page adds value beyond the manufacturer catalog with packaging guidance, application context, drop-in 0402 alternatives from the XAIPART catalog, and FAQ content synthesized for sourcing engineers.
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.

0402CS-22NXJLW - 22nH 0402 RF Ceramic Inductor | Coilcraft
The Coilcraft 0402CS-22NXJLW is a 22 nH ceramic-core RF chip inductor with 5% inductance tolerance, a 400 mA current rating, and a 300 mOhm DCR, packaged in an 0402 (1005 metric) surface-mount case. It delivers very high self-resonant frequency performance, with the 0402CS family reaching up to 12.7 GHz and a 2.8 GHz SRF at the 22 nH value, making it a workhorse for RF matching networks. An RF chip inductor is a passive two-terminal component that stores energy in a magnetic field and presents increasing impedance with frequency. Within the passive-component hierarchy (inductor -> RF inductor -> ceramic-core chip inductor), ceramic-core parts sit at the top for Q and SRF because the non-magnetic ceramic core has near-zero core losses compared with ferrite alternatives. Key features of the 0402CS-22NXJLW include its tight 5% tolerance for repeatable matching-network design, its AEC-Q200 qualification for automotive-grade reliability, and its -40 to +125 C operating range that supports under-hood and high-temperature industrial environments. The thin-film construction on the ceramic core yields a Q factor of about 53 at the 22 nH value. Technically, the unshielded wirewound-on-ceramic construction minimizes parasitic capacitance, pushing the self-resonance far above the operating band and keeping insertion loss low in 50-ohm systems. The nickel-barrier termination over solder-coated terminals supports reliable reflow soldering and compatible pick-and-place handling. Typical applications include RF matching networks in front-end modules, Bluetooth, Wi-Fi, GPS, and cellular antenna circuits, plus impedance matching in amplifiers, filters, and VCO tank circuits where compact 0402 size is essential. Design consideration: because the part is unshielded, maintain spacing from adjacent inductors and ground copper to avoid unintended magnetic coupling that shifts matching-network response. This page synthesizes verified distributor data, drop-in alternatives, and RF layout guidance not found on the manufacturer datasheet alone.
0402CS-3N3XJRW - 3.3nH 840mA RF Inductor | Coilcraft
The Coilcraft 0402CS-3N3XJRW is a 3.3 nH unshielded wirewound ceramic-core RF chip inductor rated for 840 mA with a maximum DC resistance of 66 mOhm, housed in the industry-standard 0402 (1005 metric) surface-mount package. A ceramic-core chip inductor is a passive two-terminal component that stores energy in a magnetic field created by a fine wire wound around a ceramic dielectric. In the passive-component hierarchy, it sits under inductors -> fixed inductors -> RF inductors -> chip inductors. Ceramic cores are preferred for RF work because their low magnetic permeability and low loss allow very high self-resonant frequencies and high Q at gigahertz frequencies, unlike ferrite-core inductors that become lossy above several hundred MHz. Key features of the 0402CS-3N3XJRW include a tight 5% inductance tolerance, a very high self-resonant frequency of up to 12.7 GHz for the series, and qualification to the AEC-Q200 automotive passive-component quality standard. The part is rated for operation from -40C to +125C, making it suitable for automotive and other high-temperature environments where standard commercial inductors cannot survive. Technically, the wirewound construction on a ceramic core delivers stable, predictable inductance with minimal parasitic loss, which is critical in matching networks, filters, and bias tees operating in the VHF-to-microwave range. The 66 mOhm DCR minimizes insertion loss and DC voltage drop in RF choke and bias-feed positions. Typical applications include RF matching networks in 2.4 GHz and 5 GHz radios, antenna tuning circuits, VCO tanks, and supply-line RF chokes for PA and LNA bias circuits. Its tiny 0402 footprint suits dense smartphone, IoT, and automotive telematics boards. Design tip: at 3.3 nH the self-resonant frequency is extremely high, but board parasitics still dominate - keep pads minimal and verify with the Coilcraft SPICE/L numerical models before production. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
0402CS-R10XGLW - 100nH 2% RF Chip Inductor | Coilcraft
The Coilcraft 0402CS-R10XGLW is a 100 nH (0.1 uH) ceramic-core wirewound RF chip inductor with 2% inductance tolerance, 2 ohm DCR, and 30 mA rated current, supplied in an SMD 0402 (1005 metric) package. It is AEC-Q200 qualified and rated for operation from -40C to +125C, targeting automotive and other high-temperature RF circuits. A chip inductor is a passive two-terminal component that stores energy in a magnetic field and presents inductive reactance in RF signal paths. Within the passive component hierarchy, it belongs to the fixed inductor family, specifically RF wirewound ceramic-core chip inductors used for impedance matching, resonant tanks, and EMI filtering. The ceramic core is the key differentiator versus ferrite-core chip inductors: ceramic has negligible magnetic loss and near-zero permeability drift, which pushes the self-resonant frequency extremely high and preserves Q at gigahertz frequencies. Key features of the 0402CS-R10XGLW include a very high self-resonant frequency (up to 12.7 GHz for this inductance value per the Coilcraft 0402CS series page), tight 2% tolerance for repeatable filter and VCO tuning, and a fine wirewound construction that delivers consistent performance across temperature. The AEC-Q200 qualification and 125C rating make it suitable for automotive RF modules such as keyless entry, tire-pressure monitoring, and infotainment antennas. Technically, the 100 nH value with low distributed capacitance keeps the usable inductive range well above 1 GHz; above the 12.7 GHz self-resonance the part behaves capacitively. Designers should verify the operating frequency stays comfortably below SRF and keep RF current within the 30 mA rating to avoid self-heating and drift. Typical applications include GPS, Bluetooth, and ISM-band matching networks, LC tank circuits in VCOs, RF chokes, and high-frequency bias tees. It is also used in signal conditioning and EMI filtering in compact automotive modules where board space is minimal. Design tip: keep adjacent ground planes at least one pad width away to minimize parasitic capacitance and preserve the nominal SRF, and verify DCR (2 ohms) in bias-tee insertion-loss budgets. This page adds value beyond the manufacturer catalog by consolidating drop-in alternatives, comparison tables, and design guidance for the 0402CS-R10XGLW in one place.
0402WGF0000TCE - 0 Ohm 1/16W Jumper Chip Resistor | UNI-ROYAL
The UNI-ROYAL 0402WGF0000TCE is a 0 ohm (zero-ohm jumper) thick film chip resistor rated for 62.5 mW (1/16 W) power dissipation, with a 50 V overvoltage limit and a tolerance of plus/minus 1 percent, housed in a compact 0402 (1005 metric) surface-mount package. A zero-ohm resistor, also called a jumper resistor or link resistor, is a fixed resistor with nominal resistance of 0 ohm that functions as a wire bridge on a printed circuit board. Within the resistor hierarchy, it belongs to the fixed resistor > chip resistor > thick film surface-mount resistor family. Unlike a true wire, it uses standard SMD assembly and reflow soldering processes, allowing pick-and-place machines to populate it like any other chip component, which is why 0-ohm jumpers are ubiquitous in high-density PCB design. Key features of the 0402WGF0000TCE include its tiny 1.0 mm x 0.5 mm footprint that conserves board area in dense layouts, a wide operating temperature range of -55 degrees C to +155 degrees C, and a low temperature coefficient of plus/minus 800 ppm/degrees C. The thick film construction offers small size, light weight, compatibility with both flow and reflow soldering, and reduced assembly cost when matched with automated placement equipment, per the manufacturer datasheet. Technically, the part is produced on UNI-ROYAL's UniOhm thick film chip resistor line. Although nominally 0 ohm, the actual resistance is a few milliohms, so current handling is limited by the 62.5 mW power rating and the termination current capacity; designers should treat it as a near-zero link rather than a true short for high-current paths. Typical applications include PCB configuration and strapping links, analog-digital ground separation that can be reconfigured for test, single-layer wire crossings on dense boards, current-measurement shunt pads for later substitution, and general consumer and industrial electronics where a removable link simplifies BOM variants. A key design consideration: derate the allowable current for the 0402 size; for higher-current links step up to 0603 or 0805 jumpers instead of paralleling. This page adds distributor pricing, drop-in alternatives, comparison tables, and practical design notes not found in the manufacturer datasheet, with pricing as of 2026-09-14.
0402WGF2001TCE - 2kOhm 1% 1/16W 0402 Thick Film Chip Resistor | UNI-ROYAL
The UNI-ROYAL (Uniroyal Elec) 0402WGF2001TCE is a 2 kOhm thick film chip resistor in the 0402 (1005 metric) surface-mount package, rated 62.5 mW (1/16 W) with a tolerance of plus or minus 1% and a temperature coefficient of plus or minus 100 ppm/C, with a maximum overload voltage of 50 V. A fixed chip resistor is the most fundamental passive component in electronics: a two-terminal surface-mount device whose resistance limits current, divides voltage, or sets bias points in a circuit. Chip resistors belong to the broader hierarchy of fixed resistors -> passive components -> electronic components, and the 0402 size is one of the most widely used imperial chip sizes for high-density consumer and industrial PCBs, sitting below 0603 and above 0201 in the package family. Key features of the 0402WGF2001TCE include its 1% resistance tolerance, which is sufficient for most analog precision and pull-up/pull-down applications without the cost of 0.5% or 0.1% precision grades; the plus or minus 100 ppm/C temperature coefficient, which keeps resistance drift below about 0.02% over a 20 C ambient swing; and the wide -55 C to +155 C operating temperature range suitable for automotive-adjacent and industrial environments. The device uses a thick film resistive element printed on a high-purity alumina ceramic substrate with nickel-plated termination caps and a tin (Sn) overplate for solderability in both flow and reflow soldering processes, per the manufacturer datasheet. The thick film process delivers excellent stability, low cost, and compatibility with high-speed pick-and-place assembly machines, reducing overall assembly cost. Typical applications include pull-up and pull-down resistors for MCUs and I2C lines, voltage dividers in battery-powered consumer devices, gain-setting networks around op-amps, LED current limiting in compact designs, and general BOM consolidation in IoT wearables and smartphone-class hardware where 0402 density is required. A key design consideration: at 62.5 mW rating, ensure power derating above 70 C ambient per the datasheet derating curve, and avoid exceeding the 50 V overload voltage in divider chains connected to higher rails. This page synthesizes distributor pricing, footprint-compatible alternatives from multiple manufacturers, and practical derating design notes not found in the manufacturer datasheet.
0402WGF2003TCE - 200kOhm 1% 0402 Thick Film Resistor | UNI-ROYAL
The UNI-ROYAL (Uniroyal Elec) 0402WGF2003TCE is a 200 kOhm (2003 code) thick film chip resistor in the industry-standard 0402 (1005 metric) surface-mount package, rated for 1/16 W (62.5 mW) power dissipation, 50 V maximum working voltage, and a tolerance of +/-1% with a temperature coefficient of +/-100 ppm/C over the -55 C to +155 C operating range. A chip resistor is the most fundamental passive component in electronics: a passive two-terminal device that obeys Ohm's law (V = I x R) to limit current, divide voltages, or set bias points. Within the component hierarchy it belongs to resistors -> passive components, and within resistors to the thick film SMD chip family, where a ruthenium-oxide-based resistive paste is printed on a ceramic substrate and laser-trimmed to value. Key features include the precision 1% tolerance (E-96 standard value 200 kOhm), the compact 1.0 mm x 0.5 mm 0402 footprint suitable for high-density automated assembly, and lead-free/RoHS-compliant construction with tin-plated terminations compatible with reflow and wave soldering. The TCE suffix denotes tape-and-reel packaging in 10,000-piece reels for high-volume pick-and-place lines. Technically, the thick film construction provides stable, low-noise performance with strong solder-reflow heat resistance. The +/-100 ppm/C TCR keeps value drift below 1% across a 100 C swing, so the resistor maintains its 1% accuracy over most of its operating envelope. The 50 V rating covers virtually all low-voltage analog and digital bias networks. Typical applications include pull-up/pull-down networks in digital logic, voltage dividers in battery-powered and IoT devices, feedback and gain-setting resistors around op-amps, RC filters, and transistor bias networks in consumer electronics, wearables, and industrial control boards. Design consideration: at 62.5 mW rated power, derate above 70 C ambient per the datasheet derating curve; a 200 kOhm value limits current to 0.25 mA at 50 V, so power is rarely the constraint in divider roles.

0402WGJ0101TCE - 100Ohm 1/16W 5% 0402 Thick Film Resistor | UNI-ROYAL
The UNI-ROYAL (Royal Ohm) 0402WGJ0101TCE is a 100 ohm thick film chip resistor in the industry-standard 0402 (1005 metric) surface-mount package, rated for 1/16 W (62.5 mW) power dissipation with a tolerance of plus/minus 5 percent and a temperature coefficient of plus/minus 100 ppm/C. The WGJ series offers a maximum overload voltage of 50 V and operates reliably across a -55C to +155C temperature range, supplied in tape and reel packaging with 10000 pieces per reel for automated high-volume assembly. A chip resistor is the most fundamental passive component in electronics: a passive component that provides a fixed electrical resistance for current limiting, voltage division, and impedance setting. It sits at the base of the passive component hierarchy (resistor -> thick film SMD resistor -> 0402 chip resistor) and appears in virtually every printed circuit board design, from consumer devices to automotive modules. Key features of the 0402WGJ0101TCE include its compact 1.0 mm x 0.5 mm footprint, which conserves board area in dense layouts; robust thick film resistive element on a ceramic substrate providing stable, long-term resistance drift characteristics; lead-free, RoHS-compliant construction with nickel-plated terminations for reliable solderability in reflow processes; and wide -55C to +155C operation suitable for automotive cabin and industrial environments. Technically, the resistive element is a ruthenium-oxide-based thick film paste printed on a high-purity alumina substrate and laser-trimmed to value. The outer terminations use a silver-palladium inner layer, a nickel barrier layer for leach resistance, and a tin (Sn) outer plating compatible with SnPb, SnAgCu, and SnBi reflow alloys. The plus/minus 100 ppm/C TCR keeps resistance shift below 1 percent across the full military-adjacent temperature span, and rated power derating applies linearly above 70C ambient. Typical applications include pull-up and pull-down networks for digital I/O, LED current limiting at low currents, RC filtering and timing circuits, voltage dividers in battery-powered portable devices, and general-purpose passive networks in IoT modules and wearables where 0402 size and low cost matter. Design consideration: at 1/16 W rating, verify that continuous dissipation stays under 62.5 mW after derating above 70C; parallel two 200 ohm 0402 parts if more power margin is needed.

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.

10D511K - 510V 10mm MOV Varistor Surge Protector | TYEE
The TYEE Products Inc 10D511K is a 10 mm radial leaded metal oxide varistor (MOV) rated 510 V varistor voltage at 1 mA, with a maximum clamping voltage of 845 V, an AC working voltage of 320 V r.m.s., and a DC working voltage of 415 V d.c. Housed in a through-hole disc package with two radial leads, it provides surge and transient overvoltage protection for one circuit. A metal oxide varistor is a voltage-dependent, nonlinear resistor built from sintered zinc oxide grains with metal oxide additives. In the power-management hierarchy of circuit protection devices, the MOV sits alongside TVS diodes, gas discharge tubes, and fuses: it is a voltage regulator of sorts for transients, clamping surges by dropping sharply in resistance above its breakdown threshold. MOVs absorb the bulk of surge energy in AC line applications, typically working with downstream fuses, GDTs, and TVS devices in a coordinated protection scheme. Key features of the 10D511K include a 459 V to 561 V varistor voltage window at 1 mA, an 845 V maximum clamping voltage at rated surge current, a single-pulse energy rating of 69 J, and a peak surge current class of 2.5 kA for an 8/20 us waveform. Its 10 mm disc size balances energy absorption capability against footprint, and a typical capacitance of about 70 pF makes it suitable for 50/60 Hz AC line use without significant loading. The device follows the industry-standard 10D511K naming convention: 10 = 10 mm disc diameter, D = disc, 511 = 510 V varistor voltage, K = +/-10% tolerance. The zinc-oxide ceramic grain structure gives it a V-I curve resembling back-to-back Zener diodes, enabling bidirectional clamping of both positive and negative transients on AC lines. Degradation occurs gradually after repeated surge exposure, so designs should follow derating and failure-mode guidelines from the manufacturer datasheet. Typical applications include AC mains input protection in switch-mode power supplies, industrial control panels, home appliances, LED drivers, telecom power front ends, and surge-protected outlets, where the MOV clamps lightning-induced and switching transients before they reach downstream electronics. For design, always place a fuse upstream of the MOV: at end of life an MOV can fail short and overheat, so an agreed disconnection method is mandatory per safety practice.

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.
157 - 7/8" Precision Industrial Potentiometer | Vishay
The Vishay Model 157 is a 7/8 inch (22.2 mm) precision industrial potentiometer offered in both bushing-mount and servo-mount versions, using a conductive plastic resistive element. It is designed for high-quality, long-life rotational position sensing in harsh industrial environments, with available sealed construction and independent linearity as tight as +/-0.25%. A precision potentiometer is a variable resistor used to provide an accurate, repeatable analog voltage proportional to shaft angle. Position sensors in this category form part of the broader sensor hierarchy: position sensor -> displacement sensor -> transducer -> electronic component. Unlike low-cost carbon-film trimmers intended for occasional adjustment, the Model 157 is built for continuous or repeated rotation in feedback loops, where linearity, low noise, and long operational life are essential. Key features of the Model 157 include a 7/8" (22.2 mm) housing diameter, conductive plastic resistance element, optional servo-mount (ball-bearing) and bushing-mount configurations, independent linearity down to +/-0.25%, and a wide operating temperature range. Sealed versions are available for dust- and moisture-prone environments. Standard resistance values are offered across the typical 1 kohm to 100 kohm range with multiple electrical travel options. The device uses a precision-machined housing with a stainless-steel shaft and a precision slip-clutch or ball-bearing servo option. The conductive plastic track is screened onto a substrate and wiped by multi-finger precious-metal contacts, giving low contact resistance variation (CRV) and long rotational life. This construction is well suited to closed-loop servo systems, where low electrical noise and high linearity directly translate to position accuracy and minimal dead-band. Typical applications include industrial valve position feedback, hydraulic actuator position reporting, machine-tool axis feedback, servo-driven robotics, and test-stand with motorized fü positioning. In each of these, the potentiometer acts as a true 3-wire or ratiometric position sensor providing an analog signal to a controller or ADC. When designing with the Model 157, pay attention to shaft loading, mounting orientation, and - for servo-mount versions - bearing preload. Derate the wiper current to the microampere range to minimise self-heating and to preserve long-term linearity, and always use the part in a voltage-divider (ratiometric) configuration rather than as a true two-terminal rheostat. This page synthesizes distributor pricing, same-family alternatives, and practical design notes not found in the manufacturer datasheet alone, providing information gain over the bare Vishay datasheet.
