04023C104KAT2A Présentation
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).

Applications typiques
04023C104KAT2A convient pour 6 applications: Microcontroller Supply Decoupling, Industrial Control Boards, Automotive Body Electronics, Consumer and IoT Devices, Power Supply Input Filtering, Signal Conditioning and Analog Filtering.
Microcontroller Supply Decoupling
The 04023C104KAT2A is the canonical 100 nF bypass capacitor for MCU and logic IC supply pins. Its 0.1 uF value provides a low-impedance path for switching transients in the 1 MHz to 100+ MHz range, while the X7R dielectric keeps performance stable from -55C to +125C. The 0402 (1005 Metric) case allows placement within 2-3 mm of each supply pin, minimizing loop inductance that would otherwise defeat high-frequency bypassing. The 25V rating gives large headroom on 3.3V and 5V rails, so DC-bias capacitance derating is negligible at those voltages. Place one part per supply pin plus bulk capacitance at the regulator output per the manufacturer application guidance.

Industrial Control Boards
Industrial PLC I/O boards and motor-control interface cards operate across wide ambient temperatures, and the 04023C104KAT2A's X7R dielectric holds capacitance within +/-15% from -55C to +125C, ensuring filter corner frequencies and decoupling effectiveness do not drift with factory-floor temperature swings. The 25V rating directly supports 24V industrial logic rails with margin, a rating many 16V 0402 parts cannot offer. Its nickel-barrier terminations withstand the thermal cycling and humidity exposure typical of industrial environments, and RoHS compliance keeps export assemblies conformant. Use it for analog input filtering, relay-driver rail bypass, and RS-485 transceiver supply decoupling where stability over temperature is mandatory.
Recommandé
Automotive Body Electronics
For non-safety-critical automotive body modules such as lighting control, seat adjustment, and window lift units, the 04023C104KAT2A provides 25V-rated bypassing compatible with 12V automotive battery systems, including load-dump-protected rails after a TVS clamp. The -55C to +125C X7R operating window matches under-hood-adjacent and passenger-compartment module requirements, and the 0402 footprint supports the high component density these modules demand. Per the manufacturer datasheet, the termination system is compatible with standard reflow lines used by tier-one EMS providers. For safety-critical or powertrain zones, select an AEC-Q200-qualified variant instead and verify with KYOCERA AVX.
Recommandé
Consumer and IoT Devices
Smart-home sensors, wearables, and battery-powered IoT nodes favor the 04023C104KAT2A because its 0402 (1005 Metric) size conserves board area on dense wireless modules while delivering the standard 100 nF per-supply-pin decoupling recommended for SoCs and radio chips. The 25V rating covers both 3.3V logic rails and single-cell charging circuits with large margin, and low ESR X7R construction keeps supply ripple low for sensitive RF front ends. At typical IoT bias levels of 1.8V to 3.6V, DC-bias capacitance derating is small, so effective decoupling stays near nominal. Its RoHS compliance and tape-and-reel supply fit high-volume SMT lines without process changes.
Recommandé
Power Supply Input Filtering
On the input of DC-DC converters and LDO regulators, the 04023C104KAT2A serves as a local input filter that suppresses conducted EMI before it reaches the switching element. The 25V rating supports 24V industrial brick inputs and 12V automotive rails, while the low-ESR ceramic construction avoids the ESR zeros that destabilize some LDO control loops. The part withstands the inrush and ripple currents of typical 1-5W converters thanks to the robust AVX 0402 termination system. Designers should note that X7R capacitance derates under DC bias, so at rails approaching 20V the effective filtering capacitance is lower than nominal; add a second parallel capacitor where attenuation margins are tight.
Recommandé
Signal Conditioning and Analog Filtering
In op-amp gain stages, RC low-pass filters, and ADC reference bypass networks, the 04023C104KAT2A's +/-10% K tolerance and X7R temperature stability keep filter corner frequencies predictable across the -55C to +125C range. A 100 nF value pairs with common 1k-100k resistor values to form anti-aliasing and noise filters in the 100 Hz to 1.6 kHz range. Design caution: for precision filters where harmonic distortion matters, X7R's voltage coefficient and piezoelectric behavior can introduce nonlinearity at large AC amplitudes; for those nodes, prefer a C0G/NP0 dielectric instead. For decoupling analog supply rails and mid-supply bias nodes, this part is fully appropriate and cost-effective.

Notes de conception
DC bias derating is the most common X7R design mistake. A 25V-rated 0.1 uF part can lose a large fraction of nominal capacitance when biased near its rated voltage. At 3.3V or 5V rails the effect is small, but at 20V+ inputs verify actual capacitance at the working bias from the manufacturer bias curves. For timing or filter nodes, prefer C0G dielectric, and never use X7R values in precision integrators without bench verification.
Use the standard 0402 land pattern with short, symmetric traces to reduce loop inductance and prevent tombstoning during reflow (unequal pad thermal mass is a frequent cause on this small case). Place decoupling capacitors within 2-3 mm of the IC supply pin and connect to the plane with short via stubs. Follow the reflow profile in the manufacturer datasheet; SAC305 peak around 245-250C is acceptable for the nickel-barrier termination.
X7R dielectrics age - capacitance decreases roughly 1-3% per decade-hour of life. For products with 10+ year service expectations, derate nominal capacitance in filter calculations, or specify C0G. Additionally, Class 2 ceramics are piezoelectric: in high-amplitude AC or vibration environments they can inject audible or measurable noise; keep X7R parts out of sensitive analog signal paths and microphone preamp vicinity.
