What is GRM21A7U2E471JW31D MLCC?
The GRM21A7U2E471JW31D is an SMD multilayer ceramic capacitor manufactured by Murata. Key specs include 470 pF capacitance, 250 V rated voltage, U2J dielectric, and a ±5% tolerance. RoHS compliant, it is designed for stable, low-loss filtering and decoupling in high-voltage circuits.
✔ RoHS Compliant / ✔ 0805 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Power supply decoupling: The 250 V rating and U2J dielectric ensure minimal capacitance loss under DC bias, making it ideal for high-voltage rail smoothing.
- RF & communication modules: U2J offers low dielectric absorption and stable temperature coefficient, critical for precise 470 pF timing circuits in transceivers.
- Automotive sensor interfaces: ±5% tolerance guarantees consistent performance in harsh environments; small 0805 footprint saves board space in ECU modules.
Key Features & Advantages
- High voltage stability: U2J dielectric provides low DC bias derating, maintaining over 90% capacitance at 250 V.
- Ultra-tight tolerance: ±5% ensures accurate filtering and timing without requiring additional trim components.
- Compact 0805 case: Delivers 470 pF in a small footprint, enabling dense PCB layouts for portable and industrial designs.
Frequently Asked Questions
- Q: What makes GRM21A7U2E471JW31D different from a standard X7R MLCC?
A: Unlike X7R, the U2J dielectric has a very low capacitance change over temperature (≈ -750 ppm/°C) and negligible aging, making it more predictable for precision circuits like resonant tanks or high-voltage filters. - Q: Is GRM21A7U2E471JW31D 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 and flexible quantities for low-volume needs.
