MLCC GRM21BR61H475ME51L

What is GRM21BR61H475ME51L MLCC?

The GRM21BR61H475ME51L is an SMD multilayer ceramic capacitor manufactured by Murata. Key specs include 4.7µF capacitance, 50V voltage rating, X5R dielectric, and ±20% tolerance. RoHS compliant, it is designed for reliable decoupling and energy storage in compact circuits.

✔ RoHS Compliant  /  ✔ 0805  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 4.7µF capacitance at 50V provides stable bulk storage for power rails in automotive and industrial converters, while the X5R dielectric ensures minimal capacitance change over -55°C to +85°C.
• Decoupling for High-Speed Digital ICs: With a 4.7µF value and 0805 footprint, this MLCC effectively suppresses mid-frequency noise on 3.3V or 5V supply lines of FPGAs and microcontrollers.
• Sensor Signal Conditioning: The ±20% tolerance accommodates temperature-drift compensation in analog sensor circuits, and the 0805 size fits space-constrained PCB layouts near sensor modules.

Key Features & Advantages

• High Capacitance Density: The 4.7µF rating in an 0805 package enables space savings without sacrificing power integrity in multi-layer designs.
• Robust Voltage Margin: A 50V rating provides a 2.5x derating factor over typical 20V rails, reducing the risk of DC bias failure in automotive or industrial environments.
• Wide Temperature Stability: X5R dielectric offers predictable capacitance within -55°C to +85°C, ensuring consistent performance across seasonal extremes.
