What is GRM31BR73A222KW01L MLCC?
The GRM31BR73A222KW01L is an SMD capacitor manufactured by Murata (村田). Key specs include 2200PF capacitance, 1KV voltage rating, X7R dielectric, and ±10% tolerance. RoHS compliant, it is designed for high-voltage decoupling and filtering in space-constrained designs.
✔ RoHS Compliant / ✔ SMD / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC Converter Output Filtering: The 1KV voltage rating and 2200PF capacitance provide effective high-frequency noise suppression in high-voltage power rails.
- LED Lighting Drivers: X7R dielectric ensures stable capacitance over a wide temperature range, while the 1206 package supports compact ballast designs.
- Industrial Control Modules: ±10% tolerance and Murata reliability guarantee consistent performance in harsh environments where voltage spikes can exceed 500V.
Key Features & Advantages
- High Voltage Handling: 1KV rating enables direct use in 48V systems and flyback snubber circuits without derating concerns.
- Temperature Stable X7R: Capacitance change within ±15% from -55°C to +125°C ensures predictable filtering across operating conditions.
- Compact 1206 Footprint: Balances voltage capability with board space efficiency, replacing larger 1210 or 1812 parts in many designs.
Frequently Asked Questions
- Q: What makes GRM31BR73A222KW01L different from a standard X7R capacitor?
A: This part combines 1KV voltage rating in a 1206 body — higher than typical X7R parts which are often limited to 50V or 100V in this case size. - Q: Is GRM31BR73A222KW01L 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.
