MLCC GCM31A5C3A390FX01D

What is GCM31A5C3A390FX01D MLCC?

The GCM31A5C3A390FX01D is an SMD capacitor (MLCC) manufactured by Murata（村田）. Key specs include 39pF capacitance, 1kV voltage rating, C0G/NP0 dielectric, 1206 case size, and ±1% tolerance. RoHS compliant, it is designed for high-precision, high-voltage decoupling and timing circuits.

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

Typical Applications & Why This Part Fits

• High-Voltage Feedback Networks: The 1kV rating and ±1% tolerance ensure stable voltage division in power supply feedback paths without drift.
• Resonant Tank Circuits: C0G/NP0 dielectric provides negligible capacitance change over temperature and bias, making it ideal for LC oscillators requiring 39pF at high voltage.
• High-Impedance Node Decoupling: In precision analog front-ends, the low leakage of C0G and tight ±1% tolerance maintain signal integrity at 1206 footprint.

Key Features & Advantages

• High Voltage Rating (1kV): Enables direct decoupling of high-voltage bus lines without series stacking.
• C0G/NP0 Dielectric: Offers ultra-stable capacitance across -55°C to +125°C and up to rated voltage – critical for timing and filtering.
• ±1% Tolerance: Provides predictable performance in precision circuits, eliminating calibration or selection costs.

Frequently Asked Questions

1. Q: What makes GCM31A5C3A390FX01D different from a standard 1206 MLCC?
