MLCC GRM31C5C3A102FWA3L

What is GRM31C5C3A102FWA3L MLCC?

The GRM31C5C3A102FWA3L is a multilayer ceramic chip capacitor manufactured by Murata. Key specs include 1000pF capacitance, 1kV rated voltage, C0G/NP0 dielectric, and a ±1% tolerance. RoHS compliant, it is designed for high-voltage, high-precision filtering and decoupling.

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

Typical Applications & Why This Part Fits

• Industrial Power Supplies: The 1kV voltage rating and C0G/NP0 stability make it ideal for snubber circuits and DC-link filtering where high voltage spikes occur.
• Automotive On-Board Chargers: ±1% tolerance ensures accurate capacitance in resonant converters, while the 1206 case size allows compact layout on high-voltage boards.
• High-Frequency Communication Modules: C0G/NP0 provides near-zero capacitance drift with temperature, critical for VCO and PLL loop filter applications.

Key Features & Advantages

• High Voltage Rating (1kV): Enables direct use in 400V–800V bus systems without series stacking, simplifying BOM and reducing board space.
• Tight Tolerance (±1%): Delivers predictable performance in timing, resonant, and frequency-selective circuits, minimizing design margin waste.
• Stable C0G/NP0 Dielectric: Capacitance change is less than ±30ppm/°C from -55°C to +125°C, ensuring consistent operation across temperature extremes.

Frequently Asked Questions

1. Q: What makes GRM31C5C3A102FWA3L different from a standard 1000pF MLCC?
   A: It combines a 1kV voltage rating with a ±1% tolerance and C0G/NP0 dielectric—most standard 1000pF capacitors only offer X7R or lower voltage ratings, making this part suitable for high-reliability, high-voltage designs.
2. Q: Is GRM31C5C3A102FWA3L 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 flexibility for design validation builds.

Cross Reference & Alternative Sourcing
