MLCC GRJ31CR71H475KE11L

What is GRJ31CR71H475KE11L MLCC?

The GRJ31CR71H475KE11L is a high-reliability SMD capacitor manufactured by Murata (村田). Key specs include 4.7μF capacitance, 50V voltage rating, X7R dielectric, and 1206 footprint with ±10% tolerance. RoHS compliant, it is designed for stable decoupling and filtering 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 4.7μF capacitance at 50V offers ample ripple absorption for moderate-power rails, while X7R ensures stable capacitance over -55°C to +125°C.
• Automotive Sensor Module Decoupling: The robust 1206 package and ±10% tolerance guarantee consistent performance under vibration and thermal cycling, matching Murata’s automotive-grade quality.
• Industrial Control I/O Buffering: High 50V rating allows direct connection to 24V industrial buses, and the 4.7μF value provides sufficient energy reserve for transient suppression.

Key Features & Advantages

• High Capacitance Density: 4.7μF in a compact 1206 case reduces board space while meeting 50V requirements, ideal for miniaturized designs.
• Stable X7R Dielectric: Low capacitance drift with temperature (±15% from nominal) ensures reliable operation in harsh environments.
• ±10% Tight Tolerance: Minimizes design margin requirements, enabling precise filter cutoff frequencies and consistent circuit behavior.
