What is GRM31A5C2J221JW01D MLCC?
The GRM31A5C2J221JW01D is a high-voltage SMD capacitor manufactured by Murata. Key specs include 220pF capacitance, 630V rated voltage, C0G/NP0 dielectric, 1206 case size, and ±5% tolerance. RoHS compliant, it is designed for stable performance in high-stress circuits.
✔ RoHS Compliant / ✔ SMD / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC Converter Snubbers: With 630V rating and low 220pF value, it suppresses high-frequency ringing in power conversion stages without excessive power loss.
- High-Impedance Filter Networks: The C0G/NP0 dielectric ensures capacitance stability over temperature and voltage, critical for precision timing or filter circuits.
- Automotive On-Board Charger Resonant Tanks: The 1206 package and robust Murata construction handle vibration and thermal cycling while the 630V rating supports 400V bus systems.
Key Features & Advantages
- High Voltage Rating (630V): Enables direct connection to HV rails in industrial PSUs and EV auxiliary converters, reducing component count.
- C0G/NP0 Dielectric: Delivers near-zero capacitance change across -55°C to +125°C, ideal for frequency-determining and coupling applications.
- 1206 Case Size: Balances power handling with PCB footprint; standard size simplifies assembly and rework in mixed-technology boards.
Frequently Asked Questions
- Q: What makes GRM31A5C2J221JW01D different from a standard 220pF MLCC?
