✔ RoHS Compliant  /  ✔ 0603  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Power decoupling in IoT modules: The 2.2µF value and 25V rating provide ample charge storage for MCU transient currents, while the X6S dielectric ensures stable performance from -55°C to +105°C.
• Filtering in battery-powered wearables: With low DC bias loss due to X6S characteristic, this 0603 package MLCC maintains 80%+ nominal capacitance at rated voltage, ideal for space-constrained designs.
• Signal coupling in audio codecs: ±10% tolerance allows precise AC coupling without significant amplitude variation, and the 0603 footprint matches miniaturized PCB layouts.

Key Features & Advantages

• X6S Dielectric: Offers broad temperature range (-55°C to +105°C) with ±22% capacitance change, suitable for automotive and industrial ambient conditions.
• 2.2µF at 25V: Balances high capacitance density with rated voltage margin, reducing the number of parallel capacitors needed in 3.3V or 5V rails.
• 0603 Compact Package: Enables dense board assembly for handheld devices while maintaining good solder joint reliability.

Frequently Asked Questions

1. Q: What makes GRT188C81E225KE13D different from a standard 0603 MLCC?
