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

Typical Applications & Why This Part Fits

• High-Voltage Snubber Networks: The 250V rating and 0805 footprint enable compact snubbing in switch-mode power supplies, reducing voltage spikes while maintaining board space efficiency.
• Timing & Oscillator Circuits: U2J dielectric ensures almost zero capacitance drift with temperature, preserving frequency accuracy in precision timing modules.
• DC-Link Filtering: 220pF value combined with high voltage tolerance suits it for noise decoupling in 48V telecom power buses and similar rail filtering.

Key Features & Advantages

• U2J Dielectric: Class 1 ceramic offering extremely stable capacitance (–750±120 ppm/°C), ideal for resonant and filter applications.
• 250V Rated Voltage: Strong safety margin for circuits operating above typical 50V/100V limits, reducing derating concerns in 0805 package.
• Murata GCM Series Construction: Nickel barrier termination and strict process control deliver consistent performance and long-term reliability.

Frequently Asked Questions

1. Q: What makes GCM21A7U2E221JX01D different from a standard X7R MLCC?
   A: Unlike X7R, the U2J dielectric provides a practically linear and minimal capacitance change over temperature, making it suitable for timing and frequency-sensitive designs where X7R’s capacitance variation would cause instability.
2. Q: Is GCM21A7U2E221JX01D 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: Flexible small-batch orders and fast BOM kitting support are available for prototyping and production ramp-ups.
