MLCC GRM21BR71C105KA01K

What is GRM21BR71C105KA01K MLCC?

The GRM21BR71C105KA01K is a high-reliability SMD capacitor manufactured by Murata. Key specs include 1 µF capacitance, 16 V rated voltage, X7R dielectric, and ±10% tolerance. RoHS compliant, it is designed for stable decoupling and filtering in space-constrained circuits.

✔ RoHS Compliant  /  ✔ 0805  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• DC-DC Converter Output Smoothing: The 1 µF capacitance at 16 V rating provides effective ripple reduction in power modules operating below 16 V, while X7R ensures stable capacitance over -55°C to +125°C.
• I/O Line Decoupling: With ±10% tolerance and compact 0805 package, this MLCC fits high-density PCB layouts for decoupling digital signal lines in industrial control boards.
• Automotive ECU Bypass: Murata’s strict quality control and X7R temperature characteristics make it suitable for bypass applications in engine control units where thermal cycling is common.

Key Features & Advantages

• High Capacitance Density: Achieves 1 µF in a standard 0805 size, enabling board space savings without sacrificing filtering performance.
• Wide Temperature Range: X7R dielectric guarantees only ±15% capacitance change from -55°C to +125°C, ensuring reliable operation in harsh environments.
• Low ESR & ESL: Murata’s multilayer construction minimizes parasitic resistance and inductance, improving high-frequency bypass effectiveness.
