MLCC GRM21BR71C225KA12K

What is GRM21BR71C225KA12K MLCC?

The GRM21BR71C225KA12K is a multi-layer ceramic capacitor (MLCC) manufactured by Murata. Key specs include 2.2µF capacitance, 16V rating, X7R dielectric, and ±10% tolerance. RoHS compliant, it is designed for stable decoupling and filtering in surface-mount assemblies.

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

Typical Applications & Why This Part Fits

• Power supply decoupling: The 2.2µF capacitance at 16V provides effective local energy storage and noise suppression for ICs operating in 3.3V or 5V rails.
• Automotive infotainment modules: X7R dielectric ensures capacitance stability over -55°C to +125°C, making it suitable for under-hood electronics where temperature swings are common.
• IoT sensor nodes: The compact 0805 footprint allows high-density board layouts, while the ±10% tolerance maintains consistent filter performance in wireless transceivers.

Key Features & Advantages

• 2.2µF in 0805 case: Delivers high capacitance density for space-constrained designs without sacrificing voltage margin.
• 16V DC rating: Provides ample headroom for 12V bus rails and ensures reliable operation under voltage transients.
• X7R dielectric: Offers low capacitance change with temperature (±15% over full range) and excellent aging characteristics.
