MLCC GRM31A5C3A471FWA1D

What is GRM31A5C3A471FWA1D MLCC?

The GRM31A5C3A471FWA1D is a high-voltage SMD capacitor manufactured by Murata. Key specs include 470pF capacitance, 1kV DC rating, C0G/NP0 dielectric, and ±1% tolerance. RoHS compliant, it is designed for precise filtering and coupling in demanding high-voltage circuits.

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

Typical Applications & Why This Part Fits

• Snubber Networks in Power Inverters: The 1kV voltage rating and stable C0G/NP0 dielectric ensure reliable absorption of voltage spikes without capacitance drift over temperature.
• Resonant Tank Circuits: The tight ±1% tolerance and low ESR of the 1206 package allow precise frequency tuning in wireless charging and RF modules.
• DC-DC Converter Feedback Loops: The 470pF value combined with NP0’s near-zero temperature coefficient maintains loop stability across –55°C to +125°C.

Key Features & Advantages

• 1kV High-Voltage Rating: Designed for industrial and automotive-grade power systems where standard 500V parts would fail prematurely.
• C0G/NP0 Dielectric: Offers exceptional capacitance stability (±30ppm/°C) and very low piezoelectric noise compared to X7R or X5R alternatives.
• ±1% Tight Tolerance: Enables consistent circuit behavior without the need for trimming, reducing manufacturing test time.

Frequently Asked Questions

1. Q: What makes GRM31A5C3A471FWA1D different from a standard 470pF X7R MLCC?
   A: The combination of a 1kV withstand voltage, C0G/NP0 dielectric, and ±1% tolerance provides superior frequency stability and reliability in high-stress environments where X7R parts would exhibit capacitance shifts and higher leakage.
2. Q: Is GRM31A5C3A471FWA1D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, meeting EU directive requirements.
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 for as few as 10 pieces.
