MLCC GRM21BC71H475KE11K

What is GRM21BC71H475KE11K MLCC?

The GRM21BC71H475KE11K is an SMD capacitor manufactured by Murata. Key specs include 4.7µF capacitance, 50V DC rating, X7S dielectric, 0805 package, and ±10% tolerance. RoHS compliant, it is designed for high-reliability decoupling and filtering in space-constrained circuits.

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

Typical Applications & Why This Part Fits

• Power supply decoupling for 12V rails: With 50V rating and 4.7µF capacitance, this MLCC effectively filters noise on intermediate voltage buses, while X7S ensures stable performance across -55°C to +125°C.
• Automotive electronic control units (ECUs): The 0805 footprint matches high-density PCB designs, and the X7S dielectric meets AEC-Q200 equivalent stability requirements for under-hood environments.
• Industrial sensor interfaces: ±10% tolerance provides predictable behavior in analog circuits, and the 4.7µF value is common for local bypassing of precision op-amps or ADCs.

Key Features & Advantages

• 4.7µF in 0805 package: Offers a strong capacitance-to-volume ratio, enabling designers to reduce board area without sacrificing decoupling performance.
• 50V DC voltage rating: Provides 3×+ margin over typical 3.3V/5V buses, minimizing risk of derating failures in harsh environments.
• X7S dielectric: Maintains capacitance within ±22% over -55°C to +125°C, offering a broader stable range than X5R for automotive and industrial use.

Frequently Asked Questions
