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

Typical Applications & Why This Part Fits

• Smartphone & Wearable Power Decoupling: The 2.2µF capacitance in a 0402 case provides effective noise filtering near processors and PMICs, saving board space while maintaining low ESR.
• IoT Module Bypass: X6S dielectric offers stable capacitance over a -55°C to +105°C range, ideal for wireless modules that experience temperature swings during transmission.
• Portable Audio Circuits: 16V rating gives ample headroom for battery-powered audio codecs, while the ±10% tolerance ensures consistent filter response across production batches.

Key Features & Advantages

• High Capacitance Density: 2.2µF in 0402 footprint reduces component count and frees PCB area for additional functionality.
• X6S Temperature Characteristic: Capacitance variation within ±22% from -55°C to +105°C, ensuring reliable operation in diverse environments.
• Murata Manufacturing Consistency: Tight process control delivers low failure rates and predictable electrical behavior for high-volume production.

Frequently Asked Questions

1. Q: What makes GRM155C81C225KE11D different from a standard X5R MLCC?
   A: The X6S dielectric provides wider temperature range (-55°C to +105°C) compared to X5R (-55°C to +85°C), making it suitable for applications near heat-generating components.
2. Q: Is GRM155C81C225KE11D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free.
3. Q: What is the MOQ? Can we get small batches?
   A: We support small batch orders and full BOM kitting at SZYY, including fast prototyping supply for design verification.
