MLCC GRM31CR71A226KE15K

What is GRM31CR71A226KE15K MLCC?

The GRM31CR71A226KE15K is an SMD capacitor manufactured by Murata. Key specs include 22µF capacitance, 10V voltage rating, X7R dielectric, 1206 package, and ±10% tolerance. RoHS compliant, it is designed for high-capacitance decoupling in space-constrained power circuits.

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

Typical Applications & Why This Part Fits

• DC/DC Converter Output Filtering: The 22µF capacitance and 10V rating provide stable bulk storage for point-of-load regulators, while X7R ensures minimal capacitance change over -55°C to +125°C.
• Power Rail Decoupling in IoT Modules: The 1206 footprint offers low ESR for high-frequency noise suppression, and the ±10% tolerance keeps voltage ripple predictable during transient loads.
• Portable Device Battery Bypass: With 22µF at 10V, this MLCC handles inrush currents from battery connections, and the X7R dielectric maintains capacitance under DC bias.

Key Features & Advantages

• High Capacitance Density: 22µF in a 1206 case reduces board space versus stacked or through-hole alternatives.
• Wide Temperature Stability: X7R material offers ±15% capacitance change across -55°C to +125°C, ideal for automotive and industrial environments.
• Lead-Free & RoHS Compliant: Murata’s manufacturing ensures full environmental compliance without sacrificing reliability.

Frequently Asked Questions

1. Q: What makes GRM31CR71A226KE15K different from a standard 22µF MLCC?
