Typical Applications

06031C103K4T2A is suitable for 6 applications: Microcontroller Power Rail Decoupling, Industrial Power Supply Filtering, Automotive Control Module Bypass, Telecom and Networking Line Card Decoupling, LED Lighting Driver Input/Output Filtering, Test and Measurement Instrumentation.

🏭

Microcontroller Power Rail Decoupling

The 06031C103K4T2A provides local charge reservoirs and high-frequency bypassing for MCU and FPGA core/IO rails. Its 10nF value sits in the classic mid-frequency decoupling band, complementing bulk 10uF capacitors and 100nF caps to cover a wide impedance spectrum, while the 100V rating allows reuse of a single BOM line across 3.3V, 5V, 12V, and 24V rails without redesign. The X7R dielectric holds +/-15% capacitance across -55C to +125C, so decoupling remains effective in industrial enclosures. Place each capacitor within 2-3 mm of the IC power pin with short, wide traces; the 0603 case minimizes loop inductance compared with larger formats. Expect DC-bias derating to reduce effective capacitance, and parallel multiple units on high-current rails.

⚑

Industrial Power Supply Filtering

In AC-DC and DC-DC industrial supplies, the 06031C103K4T2A serves as snubber, Y-cap-free EMI filter element, and control-side bypass. The 100V DC rating suits 48V telecom and 24V industrial buses with derating headroom, and the X7R formulation tolerates the -40C cold starts and +125C hot spots typical of industrial power enclosures. Compared with electrolytic solutions, the MLCC adds no wear-out mechanism and negligible ESR, improving filter Q when paired with ferrite beads. Designers should account for X7R voltage coefficient when sizing filter corner frequencies, since effective capacitance at operating bias is lower than nominal 10nF. The nickel-barrier termination resists solder leaching during wave-soldered power-board assembly.

πŸš—

Automotive Control Module Bypass

Automotive ECUs and body-control modules require capacitors stable across -40C to +125C ambient extremes, which the X7R dielectric of the 06031C103K4T2A satisfies with its +/-15% temperature characteristic. The 100V rating covers load-dump-protected 12V rails and 48V mild-hybrid subsystems. For boards subject to vibration and thermal-cycling-induced flexure, KYOCERA AVX's FLEXITERM variant 06031C103K4Z2A offers the same electricals with flexible terminations that dramatically reduce flex-crack short-circuit failures - a documented MLCC failure mode in under-hood environments. Qualify the termination type against your board rigidity and AEC-Q-like stress profile; the standard T2A termination is appropriate for rigid, screwed-down boards.

🌐

Telecom and Networking Line Card Decoupling

Telecom line cards mixing 48V phantom-power domains and low-voltage PHY rails exploit the 06031C103K4T2A's 100V rating to standardize one MLCC across voltage domains, simplifying procurement and placement libraries. Its 10nF X7R value provides mid-frequency bypass for serializers, PHY chips, and clock distribution ICs, while the 0603 footprint supports dense routing on 8-16 layer boards. The nickel-barrier matte-tin terminations withstand multiple reflow passes common in double-sided card assembly. Because telecom boards run continuously, X7R aging (1-2% per decade-hour) has largely settled by deployment and does not affect bypass function. Place one capacitor per power pin and distribute bulk 1uF+ capacitance per bank for best PDN impedance.

πŸ’‘

LED Lighting Driver Input/Output Filtering

LED drivers, both constant-current switching regulators and linear drivers, generate ripple at the switching frequency that the 06031C103K4T2A can filter on sense and control nodes. The 100V rating supports direct placement on 48V LED-string rails used in commercial lighting, and the 0603 case keeps EMI-critical loops small. Its low ESR improves input-filter damping when combined with a bulk electrolytic, though designers should verify the X7R DC-bias derating so the filter corner does not shift under full bus voltage. The -55C to +125C operating range covers enclosed luminaire temperatures. For audible-noise-sensitive dimming applications, note that X7R ceramics exhibit piezoelectric effects; use the part on DC nodes rather than across audible-frequency ripple sources.

πŸ”§

Test and Measurement Instrumentation

Bench instruments, data-acquisition front ends, and probe electronics use the 06031C103K4T2A for supply bypass around analog front-end ICs where the -55C to +125C X7R stability keeps power-supply filtering predictable across calibration conditions. The +/-10% K tolerance provides tighter initial-value control than M-coded parts, useful where RC time constants set bandwidth or trigger thresholds. Designers should avoid X7R parts directly in the precision signal path - dielectric absorption and voltage coefficient make C0G preferable there - but for rail bypass the X7R's high volumetric density wins. The 0603 land pattern also matches standard ICT and AOI inspection libraries used in instrument manufacturing, and RoHS matte-tin terminations suit lead-free reflow profiles.

What is the capacitance and voltage rating of 06031C103K4T2A?
The 06031C103K4T2A is a 10000 pF (0.01 uF / 10 nF) MLCC rated at 100V DC with a +/-10% tolerance. According to the KYOCERA AVX datasheet and DigiKey product listing, it uses an X7R temperature-stable dielectric in a 0603 (1608 metric) surface-mount package, making it suitable for decoupling on 12V, 24V, and 48V rails with substantial voltage headroom.
What is the price of 06031C103K4T2A?
The 06031C103K4T2A is an ultra-low-cost passive component; LCSC lists it from approximately $0.0082 per unit in stock as of 2026-09-14. Volume pricing at distributors such as DigiKey and Mouser typically falls in the $0.005 to $0.02 range depending on quantity break, with 1000-piece reel quantities near the bottom of that range. Final pricing varies with distributor stock and exchange rates, so always confirm live quotes before ordering.
Where to buy 06031C103K4T2A online?
The 06031C103K4T2A is available from major authorized distributors including DigiKey (product ID 1598665), Mouser (stock number 581-KAM15AR72A103KT), Newark (stock number 55J3222RL), LCSC (part C597087), and TTI, Inc. All list the part as in stock and shipping as of 2026-09-14. XAIPART also offers this part for direct order. Always buy from authorized channels to avoid counterfeit MLCCs, which are common in the surplus ceramic capacitor market.
Is 06031C103K4T2A in stock and what is the lead time?
Yes, the 06031C103K4T2A is in stock at multiple distributors as of 2026-09-14. DigiKey states 'buy now, ships today' and LCSC confirms in-stock availability with free datasheet access. Standard lead time for in-stock MLCCs is same-day to next-day dispatch from DigiKey, Mouser, and Newark. Because commodity X7R capacitors are high-volume items, distributors typically hold deep stock, and long allocation lead times seen during component shortages are not currently reported for this MPN.
Where to download the 06031C103K4T2A datasheet PDF?
The official 06031C103K4T2A datasheet PDF is hosted by KYOCERA AVX at spicat.kyocera-avx.com/datasheet/06031C103K4T2A. Free mirrors are also available on Octopart, DigiKey, and LCSC product pages. The datasheet covers the how-to-order code system, dimensional drawings for the 0603 (1608 metric) case, X7R temperature characteristics, and termination specifications. Avoid third-party PDF aggregators of uncertain provenance when design accuracy matters.
What is the difference between 06031C103K4T2A and 06031C103KAT2A?
The two parts differ only in termination style. According to the FindIC comparison database, both are AVX 0603 10nF 100V X7R capacitors with identical terminals and packages, and FindIC classifies 06031C103KAT2A as a complete replacement. The K4T2A suffix specifies matte-tin nickel-barrier termination; the KAT2A uses AVX's standard termination. For most reflow assemblies they are fully interchangeable, but verify termination plating requirements if you use wave soldering or lead-free alloys with specific wetting requirements.
Can 06031C103K4Z2A replace 06031C103K4T2A?
Yes, with one design consideration. The 06031C103K4Z2A is the FLEXITERM version from the same AVX family: same 10nF, 100V, X7R, 0603 parameters, but with flexible polymer terminations designed to absorb board flexure and reduce flex-crack failures. FindIC lists it as a direct alternative. Choose the Z2A variant for boards subject to mechanical bending or thermal cycling stress (automotive, handheld); the standard T2A is fine for rigid, well-supported PCBs and is typically slightly cheaper.
What is the best Vishay equivalent for 06031C103K4T2A?
The best cross-brand equivalent found in verified web data is the Vishay Vitramon VJ0603Y103KXBAC31, listed by FindIC as an alternative part. It matches the key parameters: 0603 case, 10nF, 100V, X7R dielectric, +/-10% K tolerance. Because MLCCs are two-terminal components, cross-brand substitution requires no pinout change - only verification of case dimensions, termination finish, and DC-bias derating behavior in your specific circuit. Note that effective capacitance under bias can differ between brands.
06031C103K4T2A vs Murata GRM188 series - which should I choose?
Both are credible 0603 10nF 100V X7R choices. Choose the KYOCERA AVX 06031C103K4T2A when you want AVX's proven matte-tin nickel-barrier termination and pricing from the AVX distribution channel; choose a Murata GRM188R72A103K equivalent when your BOM is already Murata-sourced or when Murata's published DC-bias characteristics better match your derating budget. Electrically both meet the same nominal spec, but second-source qualification should include measuring effective capacitance at your actual operating bias voltage.
When should I choose 06031C103K4T2A over a C0G capacitor?
Choose the X7R 06031C103K4T2A when you need decoupling, bypass, or filtering where volumetric efficiency and low cost matter more than capacitance precision. Choose a C0G/NP0 alternative when your circuit demands negligible capacitance drift, zero piezoelectric noise, or low dielectric absorption - for example timing circuits, precision integrators, and analog filters. X7R loses roughly 1-2% capacitance per decade-hour of aging and derates under DC bias, while C0G holds value nearly perfectly but would require a physically larger case at 10nF/100V.
Is 06031C103K4T2A suitable for 48V power rail decoupling?
Yes, the 100V DC rating gives the 06031C103K4T2A comfortable margin on 48V rails, and its X7R dielectric maintains +/-15% capacitance across the full -55C to +125C range. One caution: X7R capacitance derates significantly under DC bias, so the effective capacitance at 48V may be well below the nominal 10nF. Verify the DC-bias characteristic from the KYOCERA AVX datasheet or simulation tool, and parallel additional capacitors if your decoupling budget depends on the nominal value.
Is 06031C103K4T2A RoHS compliant and lead-free?
Yes. According to the DigChip specification record and distributor listings, the 06031C103K4T2A is RoHS compliant and uses lead-free nickel-barrier terminations with matte-tin plating, compatible with standard lead-free reflow profiles (typical SAC alloys). The nickel barrier layer also protects against leaching during wave or hand soldering. Always confirm current compliance certificates through KYOCERA AVX's product page or your distributor, as compliance documentation is updated periodically.
What are the key specifications of 06031C103K4T2A engineers should know?
The 06031C103K4T2A is a KYOCERA AVX MLCC with 10000 pF capacitance, +/-10% tolerance, 100V DC rating, X7R Class II dielectric stable from -55C to +125C (+/-15% capacitance change), in a 0603 (1608 metric) surface-mount package with matte-tin nickel-barrier terminations, supplied on 7-inch tape and reel for automated assembly, and RoHS compliant. It is intended for general-purpose decoupling, bypass, and filtering. These facts come directly from the DigiKey listing and the KYOCERA AVX datasheet.
Hey Google, what can replace 06031C103K4T2A?
Verified drop-in replacements include the same-brand AVX 06031C103KAT2A (identical parameters, standard termination) and 06031C103K4Z2A (FLEXITERM flexible-termination version), plus the cross-brand Vishay Vitramon VJ0603Y103KXBAC31, which matches 0603, 10nF, 100V, X7R, and K tolerance. Because MLCCs are two-terminal parts, all these alternatives land on the same PCB land pattern. Confirm DC-bias derating curves for whichever substitute you qualify, since X7R effective capacitance under bias varies by manufacturer.
How does the X7R dielectric in 06031C103K4T2A behave under temperature and DC bias?
X7R capacitance stays within +/-15% from -55C to +125C, but it derates under applied DC voltage and ages about 1-2% per decade-hour after last heating above the Curie point. At high DC bias the effective capacitance of a 10nF X7R can fall substantially below nominal - sometimes 30-50% at the full rated 100V. The KYOCERA AVX datasheet provides the temperature characteristic; for DC-bias behavior, consult AVX's SPICE/SimSurfing-type tools or measure on your application board.
What is the lifecycle status of 06031C103K4T2A?
The 06031C103K4T2A is an active, current-production part. All major distributors - DigiKey, Mouser, Newark, LCSC, and TTI - list it as in stock with today-ship availability as of 2026-09-14, and KYOCERA AVX publishes a live datasheet. It is a mainstream commodity MLCC within the AVX 0603 X7R family, with no end-of-life or last-time-buy notices associated with the MPN in the verified data. No obsolescence risk is indicated for standard-volume procurement.

Selection Guide

Choose the 06031C103K4T2A when you need a proven 10nF/100V X7R decoupling or filtering capacitor in 0603 with matte-tin nickel-barrier terminations for lead-free reflow, and your board is mechanically rigid. Choose the same-brand 06031C103KAT2A if your procurement records or qualification file reference AVX standard termination - electrically identical, same footprint. Choose 06031C103K4Z2A (FLEXITERM) for automotive, handheld, or any assembly subject to board flexure or aggressive thermal cycling, since its flexible terminations sharply reduce flex-crack short circuits. Choose the cross-brand Vishay VJ0603Y103KXBAC31 when dual-sourcing across manufacturers is mandated or AVX stock is constrained. In all cases, verify the DC-bias derating characteristic of whichever part you qualify - X7R effective capacitance at operating voltage differs by vendor and lot, and your PDN impedance target should be validated at the derated, not nominal, value.

  • K tolerance for tighter initial accuracy (vs 06031C103KAT2A)

Design Notes

X7R capacitance derates under DC bias: the effective capacitance of this 10nF/100V capacitor can fall 20-50% below nominal at high bias fractions of the rated voltage. Estimated: if your decoupling budget assumes the full 10nF at 48V on a 100V part, verify the DC-bias curve from KYOCERA AVX before finalizing the PDN design, and parallel additional capacitors to recover the lost charge reservoir.

Place the 06031C103K4T2A within 2-3 mm of the IC power pin it decouples, with via-in-pad or short wide traces to the plane. The 0603 land pattern is standardized per IPC-SM-782-style footprints; use the vendor-recommended 1.0 mm x 1.3 mm pad geometry from the AVX datasheet for reliable self-alignment during reflow. Avoid daisy-chaining decoupling capacitors on shared traces - each capacitor deserves its own via pair to minimize loop inductance.

X7R capacitors age approximately 1-2% per decade-hour after last exposure above the Curie temperature, and exhibit piezoelectric (microphonic) behavior. Do not use this part in precision timing or sample-hold circuits, and avoid placing it near audible-ripple sources in audio or lighting-dimmer boards where acoustic noise can result. For rework, limit soldering iron contact and reflow exposure - repeated thermal shocks can crack the ceramic body.
