Typical Applications
04023R474K500BA is suitable for 6 applications: Microcontroller Power Decoupling, Industrial 24V Control Board Filtering, Automotive Body and Auxiliary Electronics, Gate Drive and MOSFET Snubber Support, IoT and Wearable Sensor Modules, LED Lighting Driver Input Filtering.
Microcontroller Power Decoupling
The 0.47 uF value in a 1.0 mm x 0.5 mm 0402 case makes the Kyocera AVX 04023R474K500BA well suited to local decoupling of MCU and FPGA supply pins, where board area is at a premium and each rail needs several capacitors placed within millimeters of the power pins. Placed directly at the pin with a short via pair to the ground plane, it supplies transient charge during clock-driven current spikes while its small loop area limits high-frequency impedance. Because X7R capacitance derates under DC bias, designers should verify effective capacitance at the rail voltage and, if needed, parallel a 0.1 uF part such as 0402B104K500NT for higher-frequency coverage.
Recommended
Industrial 24V Control Board Filtering
The 50 V DC rating of the 04023R474K500BA provides a 2x derating margin on 24 V industrial control rails, a standard reliability practice for MLCCs exposed to surges and long service life. On PLC I/O boards, sensor interfaces, and motor-control auxiliary supplies, it filters switching-regulator ripple and absorbs load-transient current. The X7R dielectric holds roughly +/-15% capacitance from -55C to +125C, matching industrial ambient requirements. Designers should account for DC-bias derating at 24 V - effective capacitance will be below the nominal 0.47 uF - and consider paralleling a second unit or stepping up to a higher-value case size where a hard minimum capacitance is specified.
Recommended
Automotive Body and Auxiliary Electronics
The X7R dielectric and 50 V rating make this 0402 MLCC appropriate for 12 V automotive auxiliary rails with derating headroom, including body-control modules, lighting drivers, and sensor signal conditioning. Its compact 0402 footprint supports high-density ECUs where thousands of passives must fit in a few square centimeters. For safety-relevant positions, confirm the AEC-Q200 qualification status of the exact ordering code with Kyocera AVX before release, since qualification can vary by series variant. Under cold crank and load-dump-adjacent conditions, the DC-bias and AC-voltage coefficients of X7R should be evaluated; paralleling this 0.47 uF part with a 0.1 uF unit improves broadband impedance.
Recommended
Gate Drive and MOSFET Snubber Support
In discrete power stages using devices such as Infineon OptiMOS or International Rectifier MOSFETs, the 04023R474K500BA can serve as a local supply-bypass capacitor near gate-driver supply pins, delivering the fast charge bursts needed during PWM switching. Its 50 V rating covers common 12 V and 24 V gate-drive rails with margin, and the 0402 case keeps the decoupling loop physically close to the driver IC, minimizing inductive overshoot on the gate rail. Because gate-charge transients are brief but high-current, verify that effective (bias-derated) capacitance and the parallel ESR/ESL network keep rail droop within the driver's operating range across the switching frequency band.
Recommended
IoT and Wearable Sensor Modules
For battery-powered IoT nodes, wearables, and smart-home sensor modules, the 0.47 uF / 0402 combination balances decoupling capacity against board space - both scarce in sub-10 mm module designs feeding radios and low-power MCUs. The capacitor buffers radio transmit bursts (for example on Wi-Fi/BLE modules) that otherwise sag the local rail, while the X7R dielectric's low loss keeps quiescent overhead negligible. Note that on 3.3 V rails the DC-bias derating of X7R is modest, so effective capacitance stays close to nominal. Pair with a smaller 0.1 uF device at each radio pin for highest-frequency decoupling and follow RF module layout guides for ground-via stitching.
Recommended
LED Lighting Driver Input Filtering
Switching LED drivers generate input ripple that must be filtered close to the driver IC; the 04023R474K500BA provides 0.47 uF of input bypass at up to 50 V, covering automotive 12 V and industrial 24 V lighting rails with derating margin. Placed at the driver VIN pin with short ground vias, it reduces conducted ripple and helps meet EMI targets when combined with the driver's inductor network. The 0402 footprint fits the tight spacing typical of LED bulb and luminaire driver boards. Evaluate ripple current handling versus X7R power dissipation at the switching frequency, and consider paralleling with an electrolytic or larger MLCC for bulk energy storage on long LED strings.

Key Differentiators
- Higher charge storage per land pattern (vs 0402B104K500NT)
- Higher voltage rating in same footprint (vs 0402X475M6R3CT)
- Tighter tolerance than high-capacitance alternatives (vs 0402X475M6R3CT)
Design Notes
X7R capacitance derates significantly with applied DC voltage. Estimated: at high bias fractions of the 50 V rating (e.g., 24 V on a 24 V rail, roughly half the rated voltage), a 0.47 uF X7R MLCC may deliver 30-60% of nominal capacitance depending on the manufacturer's bias curve. Consult the Kyocera AVX X7R datasheet DC-bias characteristics for your exact operating point and size the decoupling network for the derated effective value, not the nominal 0.47 uF.
Place the 0402 capacitor directly at the decoupled IC pin with the shortest possible via pair to the ground plane; via-in-pad or doghouse patterns minimize loop inductance. Avoid placing 0402 ceramic capacitors within 2-3 mm of board edges, mounting holes, or screw bosses - board flex can crack the ceramic and create an intermittent resistive short. Nickel-barrier terminations on this series are compatible with standard lead-free reflow profiles and reduce leaching during wave or rework soldering.
Do not confuse tolerance and dielectric codes when ordering: this part is K (+/-10%) X7R. Substituting an M-tolerance part changes worst-case capacitance by a factor of two at the distribution tails. Additionally, Class 2 X7R dielectrics exhibit aging (capacitance decay over time after last heating above the Curie point) - reflow will reset the aging clock. For timing-critical or precision analog functions, use a C0G part such as 0402CG330J500NT instead, accepting its much lower capacitance values.
Compliance Information
Compliance status was not present in the provided verified web data. Kyocera AVX MLCCs are generally RoHS-compliant, but this must be confirmed from the manufacturer product page before release; no values are asserted here without data.
