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

Typical Applications & Why This Part Fits

• DC-DC Converter Snubbers: The 1kV voltage rating and C0G/NP0 stability ensure reliable damping of voltage spikes in high-voltage power modules.
• High-Frequency Coupling/Decoupling: 180pF and low-loss C0G/NP0 characteristics suit RF coupling and decoupling in communication base stations.
• Feedback Networks: Tight ±5% tolerance in a compact 1206 package maintains consistent timing in precision sensor circuits.

Key Features & Advantages

• High Voltage Rating (1kV): Handles elevated stress without derating, reducing failure risk in industrial power supplies.
• C0G/NP0 Dielectric: Ultra-stable capacitance over temperature and voltage, essential for resonant or timing circuits.
• ±5% Tolerance: Tight control enables consistent performance without additional trimming in matched capacitor arrays.

Frequently Asked Questions

1. Q: What makes GRM31A5C3A181JW01D different from a standard MLCC?
   A: Its combination of 180pF at 1kV in a C0G dielectric delivers extreme stability for high-voltage designs where X7R alternatives drift significantly.
2. Q: Is GRM31A5C3A181JW01D 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 small-batch flexibility for quick-turn validation.
