What is GRM21BR72A474KA73K MLCC?
The GRM21BR72A474KA73K is an SMD capacitor manufactured by Murata. Key specs include 0.47µF capacitance, 100V voltage rating, X7R dielectric, and ±10% tolerance. RoHS compliant, it is designed for high-reliability decoupling and filtering in moderate-voltage circuits.
✔ RoHS Compliant / ✔ 0805 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Power supply output filtering: The 0.47µF capacitance combined with 100V rating provides effective ripple suppression in 48V or 72V bus converters, while X7R stability ensures consistent performance across -55°C to +125°C.
- DC-DC converter snubber circuits: The 0805 package size allows dense placement near switching nodes, and the ±10% tolerance ensures predictable snubber behavior without overdesign.
- Automotive infotainment modules: Meets AEC-Q200 derivative requirements (Murata’s standard reliability), and the 100V rating gives margin for load-dump transients in 12V/24V systems.
Key Features & Advantages
- High voltage rating (100V): Enables use in industrial and telecom power rails where standard 50V MLCCs would risk failure.
- X7R dielectric: Temperature-compensating characteristics with ±15% capacitance change over -55°C to +125°C, suitable for bypass and coupling.
- Compact 0805 footprint: Balances capacitance density and board space, ideal for high-component-count designs.
Frequently Asked Questions
- Q: What makes GRM21BR72A474KA73K different from a standard 0805 MLCC?
A: It offers a rare combination of 0.47µF capacitance at 100V in an 0805 case, whereas many parts at this voltage are limited to 0.1µF or require larger packages. - Q: Is GRM21BR72A474KA73K 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 with flexible reel cuts.
