What is GRM21A5C2J101JWA1D MLCC?
The GRM21A5C2J101JWA1D is a SMD capacitor manufactured by Murata. Key specs include 100 pF capacitance, 630 V DC rating, C0G/NP0 dielectric, and ±5% tolerance. RoHS compliant, it is designed for stable high-voltage decoupling in compact power circuits.
✔ RoHS Compliant / ✔ 0805 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC Converter Snubbers: The 630 V rating and C0G/NP0 stability minimize voltage derating, making it ideal for snubber networks in telecom or industrial converters.
- Sensor Bias Filtering: Low capacitance drift over temperature (C0G) ensures consistent bias decoupling for precision sensors in automotive or medical electronics.
- High-Impedance Node Bypass: The 0805 package and 100 pF value provide a low-inductance path for high-frequency noise suppression on sensitive analog lines.
Key Features & Advantages
- High Voltage & Stable Dielectric: C0G/NP0 offers near-zero capacitance change under DC bias and temperature extremes, critical for 630 V operation.
- Compact 0805 Footprint: Balances power handling with board area efficiency, suitable for dense multilayer assemblies.
- ±5% Tight Tolerance: Enables precise timing and filtering in oscillator circuits and feedback loops without extra tuning.
Frequently Asked Questions
- Q: What makes GRM21A5C2J101JWA1D different from a standard X7R high-voltage cap?
A: Unlike X7R, C0G/NP0 provides essentially no capacitance loss with applied DC voltage, so the 100 pF remains accurate even at 630 V bias. - Q: Is GRM21A5C2J101JWA1D RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free. - 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 for quick-turn builds.
