MLCC GRM31BR72J222KW01L

What is GRM31BR72J222KW01L MLCC?

The GRM31BR72J222KW01L is a high‑voltage SMD capacitor manufactured by Murata（村田）. Key specs include 2200pF capacitance, 630V rated voltage, X7R dielectric, 1206 footprint, and ±10% tolerance. RoHS compliant, it is designed for stable, high‑voltage decoupling and filtering in space‑constrained circuits.

✔ RoHS Compliant  /  ✔ SMD  /  ✔ Murata（村田） Quality  /  ✔ Long‑Term Supply

Typical Applications & Why This Part Fits

• Power Supply Output Filtering: The 630V rating easily handles bus voltages in telecom and industrial supplies, while the X7R dielectric ensures stable capacitance from -55°C to +125°C.
• Automotive & Industrial Control Units: Murata’s reliability and the 1206 package allow dense PCB layouts in engine control modules or inverter boards, where both voltage margin and temperature stability are critical.
• DC‑DC Converter Snubbers: 2200pF at 630V provides effective ringing suppression without exceeding voltage derating rules, and the ±10% tolerance keeps snubber performance consistent.

Key Features & Advantages

• 630V High Voltage Rating: Enables direct decoupling on 400V DC bus lines and 277V AC rectified rails, reducing the need for series stacking.
• X7R Temperature Stability: Capacitance change of only ±15% over the full operating range ensures predictable filtering and bypass behavior.
• Compact 1206 Case Size: Saves board space while maintaining the high voltage capability, ideal for miniaturized power modules and portable equipment.

Frequently Asked Questions

1. Q: What makes GRM31BR72J222KW01L different from a standard X7R MLCC?
   A: Most X7R parts are rated for 50V‑100V; this part delivers 630V in a common 1206 size, which is uncommon and allows one‑component voltage‑withstanding without a larger package.
2. Q: Is GRM31BR72J222KW01L RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead‑free.
3. 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 – you can order just a few pieces for testing or receive a complete kitting service for production.
