What is GRM31C7U3A102JW32L MLCC?
The GRM31C7U3A102JW32L is an SMD capacitor manufactured by Murata. Key specs include CAP CER 1000PF 1KV U2J 1206±5%. RoHS compliant, it is designed for high-voltage stability and precision coupling in demanding circuits.
✔ RoHS Compliant / ✔ SMD / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- High-Voltage DC-DC Converters: The 1kV rating and U2J dielectric ensure minimal leakage and stable capacitance under bias, critical for reliable power conversion.
- Snubber Circuits for Switching Transistors: Low-loss U2J material and ±5% tolerance provide consistent performance when suppressing voltage spikes in motor drives or inverters.
- Telecom Infrastructure Coupling: The compact 1206 footprint saves PCB space while delivering the high-voltage isolation needed for line interface and base station designs.
Key Features & Advantages
- High Voltage Rating (1kV): Enables direct use in power rail decoupling without voltage derating concerns.
- U2J Dielectric: Offers superior temperature stability and very low capacitance change under DC bias compared to X7R.
- Tight Tolerance (±5%): Guarantees precise capacitance value for filters and timing circuits where accuracy matters.
Frequently Asked Questions
- Q: What makes GRM31C7U3A102JW32L different from a standard MLCC?
A: This part uses a U2J dielectric, which provides significantly lower capacitance variation with temperature and voltage than conventional X7R or X5R types, making it ideal for high-voltage analog circuits. - Q: Is GRM31C7U3A102JW32L 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.
