What is GRM31A5C2J181JW01D MLCC?
The GRM31A5C2J181JW01D is an SMD capacitor manufactured by Murata. Key specs include 180pF capacitance, 630V DC voltage rating, C0G/NP0 dielectric, 1206 package, and ±5% tolerance. RoHS compliant, it is designed for high-voltage stability and precision timing circuits.
✔ RoHS Compliant / ✔ SMD / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- High-Voltage Power Supplies: The 630V rating ensures reliable decoupling and filtering in DC-DC converters and PFC stages where transient voltages exceed typical logic levels.
- RF & Communication Modules: C0G/NP0 dielectric offers ultra-low capacitance drift over temperature (±30ppm/°C) and high Q, making it ideal for resonant circuits and VCO tuning loops.
- Precision Timing & Feedback Networks: The ±5% tolerance coupled with stable C0G characteristics guarantees consistent time constants in oscillator and compensation circuits.
Key Features & Advantages
- High Voltage Rating (630V): Enables use in industrial and automotive-grade power rails without derating concerns.
- Class I Dielectric (C0G/NP0): Negligible voltage and temperature coefficient ensures predictable capacitance across operating conditions.
- Compact 1206 Package: Balances board space savings with adequate creepage distance for 630V applications.
Frequently Asked Questions
- Q: What makes GRM31A5C2J181JW01D different from a standard X7R capacitor?
A: Unlike X7R, this C0G/NP0 part exhibits virtually no capacitance change under DC bias or temperature variation, critical for frequency-setting and high-voltage circuits. - Q: Is GRM31A5C2J181JW01D 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.
