MLCC GCM21B5C2J102JX03L

What is GCM21B5C2J102JX03L MLCC?

The GCM21B5C2J102JX03L is an SMD capacitor manufactured by Murata. Key specs include 1000pF capacitance, 630V rated voltage, C0G/NP0 dielectric, and ±5% tolerance. RoHS compliant, it is designed for high-voltage decoupling and filtering in compact circuits.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 630V rating ensures stable operation in high-voltage power rails, while C0G/NP0 provides minimal capacitance change over temperature and voltage.
• Snubber Circuits in Switching Power Supplies: Low ESR/ESL of 0805 package and NP0 dielectric help suppress ringing and voltage spikes effectively.
• Sensor Interface Coupling: ±5% tolerance guarantees accurate signal coupling without drift, critical for precision measurement equipment.

Key Features & Advantages

• C0G/NP0 Dielectric: Ultra-stable capacitance across -55°C to +125°C, ideal for timing and resonant circuits.
• High Voltage Rating (630V): Enables direct use in 400V+ bus voltages without derating.
• Compact 0805 Footprint: Saves board space while supporting demanding voltage requirements.

Frequently Asked Questions

1. Q: What makes GCM21B5C2J102JX03L different from a standard X7R capacitor?
   A: C0G/NP0 offers near-zero capacitance change with voltage and temperature, unlike X7R which can drop 15% or more under DC bias. For 630V circuits, this stability is critical.
2. Q: Is GCM21B5C2J102JX03L 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 full BOM kitting at SZYY, including fast prototyping supply.
