What is GCM21B5C2J821FX03L MLCC?

The GCM21B5C2J821FX03L is a SMD capacitor manufactured by Murata（村田）. Key specs include 820pF capacitance, 630V rating, C0G/NP0 dielectric, and ±1% tolerance. RoHS compliant, it is designed for high-voltage precision filtering and timing circuits.

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

Typical Applications & Why This Part Fits

• High-Voltage DC-DC Converters: The 630V rating ensures reliable bypass and snubbing in power stages where standard 50V or 100V parts would fail prematurely.
• Precision Timing & Oscillator Circuits: C0G/NP0 dielectric delivers ultra-stable capacitance over temperature and voltage, while ±1% tolerance maintains tight frequency accuracy.
• Automotive & Industrial Sensor Interfaces: The 0805 package offers robust solder joint reliability, and Murata’s automotive-grade qualification supports harsh environment deployments.

Key Features & Advantages

• High Voltage Rating (630V): Provides ample headroom for 48V, 120V, and intermediate bus architectures, eliminating the need for series stacking.
• Stable C0G/NP0 Dielectric: Minimal capacitance change under DC bias and temperature extremes, critical for accurate analog and timing circuits.
• Tight ±1% Tolerance: Reduces design margins and simplifies calibration in measurement, medical, and high-fidelity audio paths.

Frequently Asked Questions
