MLCC GRM31CR71E106MA12K

What is GRM31CR71E106MA12K MLCC?

The GRM31CR71E106MA12K is a multilayer ceramic capacitor (MLCC) in the SMD capacitor category manufactured by Murata. Key specs include a capacitance of 10 µF, a rated voltage of 25 V, X7R dielectric, and a 1206 footprint with ±20% tolerance. RoHS compliant, it is designed for stable decoupling and filtering in power and signal circuits.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 10 µF capacitance at 25 V rating provides sufficient bulk storage for smoothing ripple in low-voltage rails, while X7R ensures stable capacitance over -55°C to +125°C.
• Power Supply Decoupling for ICs: With ±20% tolerance, this MLCC reliably bypasses high-frequency noise on VCC lines of MCUs, FPGAs, and RF modules.
• Automotive Infotainment Systems: The 1206 package withstands mechanical stress and vibration, and the X7R dielectric meets AEC-Q200 derating requirements for under-hood or cabin electronics.

Key Features & Advantages

• High Capacitance Density: 10 µF in a 1206 body reduces board space compared to multiple lower-value caps, simplifying layout and lowering BOM cost.
• Wide Temperature Stability: X7R characteristic ensures capacitance change within ±15% from -55°C to +125°C, critical for industrial and automotive environments.
• Low ESR & ESL: Ceramic construction delivers low equivalent series resistance and inductance, improving high-frequency transient response for sensitive loads.
