MLCC GCJ31CR71H225KA12K

What is GCJ31CR71H225KA12K MLCC?

The GCJ31CR71H225KA12K is a multi-layer ceramic capacitor (MLCC) manufactured by Murata. Key specs include 2.2µF capacitance, 50V voltage rating, X7R dielectric, 1206 case size, and ±10% tolerance. RoHS compliant, it is designed for stable decoupling and filtering in power management circuits.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Output Smoothing: The 2.2µF capacitance and 50V rating effectively filter switching noise in 12V–48V converters, while the X7R dielectric ensures stable capacitance over -55°C to +125°C.
• Industrial Sensor Power Rails: Low ESR and compact 1206 size allow dense PCB layouts in harsh environments, with the 50V withstand providing margin for 24V industrial supplies.
• Base Station Power Distribution: High reliability MLCC decouples high-frequency transients; Murata’s GCJ series offers superior mechanical strength for vibration-prone telecom equipment.

Key Features & Advantages

• High Capacitance Density: 2.2µF in a 1206 package reduces board space vs. larger form factors, enabling miniaturized designs.
• Wide Temperature Stability: X7R dielectric (±15% over -55°C to +125°C) ensures consistent performance across thermal extremes.
• Rigorous Murata Testing: Each part undergoes 100% voltage screening, guaranteeing low failure rates for long-life applications.
