What is GRM31A5C2J182FWA1D MLCC?
The GRM31A5C2J182FWA1D is a high-voltage multilayer ceramic capacitor (MLCC) manufactured by Murata. Key specs include a capacitance of 1800pF, a rated voltage of 630V, a C0G/NP0 dielectric, and a 1206 case size with ±1% tolerance. RoHS compliant, it is designed for applications demanding stable capacitance under high DC bias.
✔ RoHS Compliant / ✔ SMD / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Power supply snubber circuits: The 630V rating and C0G stability ensure reliable damping of voltage spikes without capacitance loss or aging.
- High-frequency filtering in 48V/POE systems: The 1800pF value and tight ±1% tolerance provide precise decoupling at the required impedance level.
- Timing or resonant tank circuits: C0G/NP0 dielectric offers near-zero voltage and temperature coefficient, keeping resonance accuracy over a wide temperature range.
Key Features & Advantages
- 630V DC rating: Enables direct placement on high-voltage bus rails without derating concerns, simplifying board layout.
- C0G/NP0 dielectric: Exhibits minimal capacitance shift (<±30ppm/°C) and no voltage-induced degradation, ideal for precision circuits.
- ±1% tolerance: Guarantees tight capacitance consistency, reducing the need for calibration in resonant or filter designs.
Frequently Asked Questions
- Q: What makes GRM31A5C2J182FWA1D different from a standard MLCC?
A: It combines a high 630V voltage rating with the most stable C0G/NP0 dielectric, while standard MLCCs often use class-II dielectrics that degrade under voltage and temperature. - Q: Is GRM31A5C2J182FWA1D RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, meeting EU environmental requirements. - 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 design validation.
