The GRM155C81A225KE11D is a multilayer ceramic capacitor from Murata in the SMD Capacitors category. Key specs include 2.2μF capacitance, 10V rating, X6S dielectric, 0402 package, and ±10% tolerance. RoHS compliant, it is designed for space-constrained, temperature-sensitive decoupling and filtering.

✔ RoHS Compliant  /  ✔ 0402  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Wearable & Portable Devices: The 0402 footprint and 2.2μF density enable effective power rail decoupling where PCB real estate is at a premium.
• Power Management Modules: The 10V rating provides ample headroom for 3.3V and 5V rails, while X6S dielectric ensures stable capacitance across operating temperature.
• IoT Sensor Nodes: Low-profile 0402 packaging suits miniaturized enclosures, and ±10% tolerance guarantees consistent filter performance in wireless transceivers.

Key Features & Advantages

• High Volumetric Efficiency: 2.2μF in 0402 reduces component count by consolidating multiple smaller caps on a single device.
• X6S Temperature Performance: Delivers stable capacitance from -55°C to +105°C, outperforming X5R in thermal cycling environments.
• Low ESR at High Frequencies: MLCC construction minimizes impedance for improved noise suppression in DC-DC converter input/output filtering.

Frequently Asked Questions

1. Q: What makes GRM155C81A225KE11D different from a standard 0402 X5R cap?
