MLCC GCJ31CR71E475KA12L

What is GCJ31CR71E475KA12L MLCC?

The GCJ31CR71E475KA12L is a multilayer ceramic capacitor (MLCC) manufactured by Murata. Key specs include CAP CER 4.7UF, 25V rating, X7R dielectric, and 1206±10% tolerance. RoHS compliant, it is designed for stable capacitance in compact, high-reliability circuits.

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

Typical Applications & Why This Part Fits

• Power Supply Decoupling: The 4.7µF capacitance at 25V handles ripple and transient currents in DC-DC converters and POL regulators, while the X7R characteristic ensures minimal capacitance drift over temperature.
• Input/Output Filtering: The 1206 package with ±10% tolerance provides predictable filtering for low‑frequency noise in portable electronics, IoT modules, and industrial sensors.
• Automotive Infotainment: Murata’s GCJ series is designed for automotive‑grade reliability; the X7R dielectric and 25V rating support harsh environments like engine‑bay power lines.

Key Features & Advantages

• High Capacitance Density: 4.7µF in a 1206 footprint saves board space compared to stacked film or tantalum alternatives.
• Stable X7R Dielectric: Capacitance change within ±15% from -55°C to +125°C ensures consistent filtering across temperature extremes.
• Low ESR & ESL: MLCC construction minimizes energy losses and parasitic inductance, improving ripple suppression in switching converters.
