What is KCM55V5C3A543JDL2L MLCC?
The KCM55V5C3A543JDL2L is a multilayer ceramic capacitor (MLCC) manufactured by Murata. Key specs include 0.054 µF capacitance, 1 kV voltage rating, C0G/NP0 dielectric, ±5% tolerance, and a 2SMD configuration. RoHS compliant, it is designed for high-voltage, high-stability filtering and decoupling in demanding circuits.
✔ RoHS Compliant / ✔ SMD / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Power supply snubber circuits: The 1 kV rating safely handles voltage spikes, while C0G/NP0 ensures minimal capacitance change under bias and temperature.
- High-frequency resonant tanks: Low losses and tight ±5% tolerance maintain consistent resonance in RF and wireless charging circuits.
- Automotive on-board chargers (OBC): Murata’s rugged construction and stable dielectric guarantee reliable operation under wide temperature swings and high DC bias.
Key Features & Advantages
- 1 kV rated voltage: Enables direct placement in high-voltage DC‑DC converters and inverters without series stacking.
- C0G/NP0 dielectric: Near‑zero capacitance drift over temperature and voltage, ideal for precision timing and filtering.
- ±5% tolerance: Reduces design margin waste and improves yield in impedance‑sensitive circuits.
Frequently Asked Questions
- Q: What makes KCM55V5C3A543JDL2L different from a standard MLCC?
A: Unlike standard X7R or X5R parts, this capacitor uses C0G/NP0 dielectric for exceptional stability and offers a 1 kV voltage rating—much higher than typical 50V or 100V MLCCs of similar capacitance. - Q: Is KCM55V5C3A543JDL2L RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead‑free. - Q: What is the MOQ? Can we get small batches?
A: We support small batch orders and full BOM kitting at SZYY, including fast prototyping supply. High‑volume stocking is also available.
