MLCC GRM31B7U3A471JW31L

What is GRM31B7U3A471JW31L MLCC?

The GRM31B7U3A471JW31L is a SMD capacitor manufactured by Murata. Key specs include 470pF capacitance, 1KV voltage rating, U2J dielectric, 1206 package, and ±5% tolerance. RoHS compliant, it is designed for high-voltage decoupling and snubber circuits.

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

Typical Applications & Why This Part Fits

• High-voltage DC-DC converters: The 1KV rating and stable U2J dielectric ensure reliable filtering and snubber performance in power stages.
• Industrial PFC circuits: Low capacitance drift over temperature (U2J) combined with 470pF value suits timing and EMI suppression in harsh environments.
• LED lighting drivers: Compact 1206 footprint saves board space while handling 1KV transients common in mains-connected designs.

Key Features & Advantages

• High voltage capability (1KV): Reduces part count by eliminating series-stacked capacitors in high-potential lines.
• U2J dielectric stability: ±5% tolerance and low capacitance change across -55°C to +125°C improve circuit accuracy.
• Murata quality assurance: Stringent manufacturing controls ensure consistent performance and long-term reliability.

Frequently Asked Questions

1. Q: What makes GRM31B7U3A471JW31L different from a standard X7R MLCC?
   A: The U2J dielectric offers significantly lower capacitance variation with voltage and temperature, critical for 1KV snubber and timing applications where X7R would drift.
2. Q: Is GRM31B7U3A471JW31L 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 and convenient small-batch flexibility.
