What is GRM21BR72E103KW03L MLCC?
The GRM21BR72E103KW03L is a multilayer ceramic chip capacitor manufactured by Murata. Key specs include 10000pF capacitance, 250V rating, X7R dielectric, and ±10% tolerance in an 0805 package. RoHS compliant, it is designed for stable decoupling and filtering in medium-voltage circuits.
✔ RoHS Compliant / ✔ 0805 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC Converter Output Filtering: The 250V rating and X7R stability ensure reliable filtering in power modules where voltage transients can exceed 100V.
- Industrial Sensor Interfaces: 10000pF provides adequate noise bypass for analog sensor lines, while the 0805 footprint suits compact PCB layouts in automation equipment.
- LED Lighting Drivers: With X7R’s low capacitance variation over temperature and 250V withstand capability, it matches the needs of high-voltage LED string circuits.
Key Features & Advantages
- High Voltage 250V Rating: Enables use in 48V bus systems, PoE applications, and other elevated-voltage designs without derating concerns.
- X7R Dielectric Stability: Capacitance change within ±15% from -55°C to +125°C, ensuring consistent performance across harsh industrial temperature ranges.
- Compact 0805 Case Size: Balances power handling with space savings, suitable for dense SMT assembly and high-volume pick-and-place processes.
Frequently Asked Questions
- Q: What makes GRM21BR72E103KW03L different from a standard 0805 MLCC?
A: This Murata part offers a 250V voltage rating that is higher than many general-purpose 50V or 100V 0805 capacitors, making it specifically suited for medium-voltage circuits while maintaining X7R stability. - Q: Is GRM21BR72E103KW03L 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 BOM kitting support and small-batch flexibility for prototyping supply.
