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

Typical Applications & Why This Part Fits

• Smartphone Power Rails: With 2.2µF in 0402, it delivers ample decoupling for core and memory voltage domains where board space is at a premium.
• Wearable Modules: The X6S dielectric (–55°C to +105°C) ensures stable capacitance under body-temperature variations, critical for reliable operation in fitness trackers.
• IoT Sensor Nodes: 10V rating provides comfortable margin above typical 1.8V–3.3V bus voltages, reducing derating concerns in battery-powered wireless designs.

Key Features & Advantages

• Compact 0402 Footprint: Enables high-density PCB layouts without sacrificing 2.2µF capacitance, saving over 60% board area versus 0603 equivalents.
• X6S Temperature Stability: Offers ±22% capacitance change over –55°C to +105°C, outperforming X5R in extended-temperature industrial and automotive-adjacent applications.
• Murata Production Consistency: Tight ±10% tolerance ensures predictable AC ripple filtering and timing behavior across reels, reducing design validation overhead.

Frequently Asked Questions

1. Q: What makes GRM155C81A225KE44D different from a standard X5R capacitor?
