What is GRM31BR73A152KW01L MLCC?

The GRM31BR73A152KW01L is an SMD capacitor manufactured by Murata（村田）. Key specs include 1500PF capacitance, 1KV voltage rating, X7R dielectric, 1206 package size, and ±10% tolerance. RoHS compliant, it is designed for high-voltage decoupling and filtering in compact circuit boards.

✔ RoHS Compliant  /  ✔ SMD  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• DC-DC Converters: The 1KV rating and 1500PF capacitance efficiently suppresses voltage spikes in high-voltage power modules, while the X7R dielectric offers stable capacitance over temperature.
• Snubber Circuits: In switching power supplies, this MLCC’s ±10% tolerance ensures predictable performance when damping oscillations, and the 1206 footprint fits standard assembly processes.
• Industrial Control Interfaces: For high-voltage coupling or EMI filtering in harsh environments, the X7R material provides reliable operation from -55°C to +125°C, matching industrial temperature requirements.

Key Features & Advantages

• High Voltage Handling: 1KV rating enables direct placement in 480VAC or 1000VDC rails, reducing the need for series stacking.
• Stable X7R Dielectric: Capacitance change within ±15% over -55°C to +125°C ensures consistent performance in temperature-varying environments.
• Compact 1206 Package: Saves PCB space while maintaining adequate creepage distance for high-voltage isolation.

Frequently Asked Questions

1. Q: What makes GRM31BR73A152KW01L different from a standard 1206 MLCC?
