MLCC GRT31CR71H225KE13L

What is GRT31CR71H225KE13L MLCC?

The GRT31CR71H225KE13L is a multilayer ceramic capacitor (MLCC) manufactured by Murata. Key specs include 2.2µF capacitance, 50V voltage rating, X7R dielectric, 1206 footprint, and ±10% tolerance. RoHS compliant, it is designed for stable, high-reliability 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 combined with 50V rating provides ample charge storage for output ripple reduction in converters operating up to 48V buses.
• Power Supply Decoupling: X7R dielectric ensures capacitance remains stable over -55°C to +125°C, critical for noise suppression on power rails in industrial and automotive modules.
• I/O Filtering for Sensor Interfaces: The 1206 package offers robust solder joint reliability under thermal cycling, while the ±10% tolerance guarantees consistent filter cutoff frequencies.

Key Features & Advantages

• High Voltage Rating (50V): Supports applications with elevated rail voltages, reducing the need for series stacking or derating.
• Stable X7R Dielectric: Maintains capacitance within ±15% over a wide temperature range, ensuring predictable circuit behavior.
• Compact 1206 Footprint: Balances board space and capacitance density, simplifying layout in space-constrained designs.
