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

Typical Applications & Why This Part Fits

• High-Voltage Coupling: With a 1 kV rating, this capacitor safely isolates DC bias while passing AC signals in power converters and inverters.
• Snubber Networks: The tight ±1% tolerance and C0G/NP0 temperature stability ensure consistent damping performance in switching circuits.
• Resonant Circuits: Low loss at high frequencies makes it ideal for oscillator tanks or filter stages where capacitance must remain stable.

Key Features & Advantages

• High Voltage Handling: Rated for 1 kV, enabling use in industrial and automotive power stages without derating concerns.
• Ultra-Stable Dielectric: C0G/NP0 offers near-zero capacitance change over temperature, critical for precision timing and filtering.
• Small 1206 Footprint: Saves board space while supporting high voltage, simplifying layout in dense designs.

Frequently Asked Questions

1. Q: What makes GCM31A5C3A120FX01D different from a standard MLCC?
   A: Its 1 kV rating is significantly higher than typical 50 V or 100 V parts, and the C0G/NP0 dielectric provides much better stability than X7R or X5R over temperature and voltage.
2. Q: Is GCM31A5C3A120FX01D 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 fast prototyping supply, offering flexibility for both development and low-volume production.
