What is GCM21A5C2J101FX01D MLCC?

The GCM21A5C2J101FX01D is a high-voltage SMD multilayer ceramic capacitor manufactured by Murata. Key specs include 100pF capacitance, ±1% tolerance, 630V DC rating, and C0G/NP0 dielectric. RoHS compliant, it is designed for stable, low-loss filtering and coupling in demanding circuits.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Snubber Circuits: The 630V rating and C0G stability effectively suppress voltage spikes without capacitance drift under bias or temperature.
• High‑Impedance RF Coupling: With ±1% tolerance and low C0G losses, this capacitor ensures precise coupling and minimal phase error in 50Ω transmission paths.
• Industrial Sensor Interface: The 0805 footprint saves board space, while the NPO dielectric delivers repeatable performance across -55°C to +125°C for reliable measurement chains.

Key Features & Advantages

• 630V High Voltage Rating: Provides ample margin for power rail decoupling and surge protection in automotive and industrial environments.
• ±1% Tight Tolerance: Ensures consistent capacitance in precise timing, tuning, and feedback networks, reducing calibration effort.
• C0G/NP0 Dielectric (Class I): Nearly zero capacitance change with voltage, temperature, and aging – ideal for resonant circuits and filters.

Frequently Asked Questions

1. Q: What makes GCM21A5C2J101FX01D different from a standard 100pF 0805 capacitor?
