MLCC GRM31A5C3A221JW01D

What is GRM31A5C3A221JW01D MLCC?

The GRM31A5C3A221JW01D is an SMD capacitor manufactured by Murata. Key specs include 220pF capacitance, 1kV voltage rating, C0G/NP0 dielectric, and ±5% tolerance in a 1206 case size. RoHS compliant, it is designed for stable high-voltage filtering and coupling.

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

Typical Applications & Why This Part Fits

• High‑Voltage Snubber Circuits: The 1kV withstand capability makes it ideal for suppressing voltage spikes in switching power supplies and motor drives.
• Precision Timing & Oscillator Circuits: C0G/NP0 dielectric ensures minimal capacitance change over temperature and voltage, critical for RC oscillators and timing modules.
• DC‑DC Converter Output Filtering: Low ESR/ESL combined with high voltage rating effectively reduces ripple in step‑up or isolated converters.

Key Features & Advantages

• High Voltage Rating (1kV): Enables safe operation in harsh power‑stage environments without derating.
• Class‑1 C0G/NP0 Dielectric: Offers ultra‑low capacitance drift (< ±30ppm/°C) and negligible aging, ensuring long‑term accuracy.
• Compact 1206 Footprint: Balances capacitance density and creepage distance, saving board space while maintaining 1kV isolation.

Frequently Asked Questions

1. Q: What makes GRM31A5C3A221JW01D different from a standard MLCC?
   A: It combines a 1kV voltage rating with C0G/NP0 stability in a standard 1206 package – most high‑voltage C0G parts are larger; this part delivers both performance and compactness.
2. Q: Is GRM31A5C3A221JW01D 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.
