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

Typical Applications & Why This Part Fits

• DC-DC Converter Snubber Circuits: The 630V rating and C0G/NP0 stability ensure reliable ringing suppression in high-voltage rails without capacitance loss under bias.
• Base Station Power Amplifier Biasing: ±1% tolerance guarantees consistent filter corner frequencies across multiple amplifier stages in RF infrastructure equipment.
• Industrial Motor Drive Feedback Loops: 10000pF paired with 1206 footprint allows compact layout while the Class-1 dielectric provides minimal drift over temperature for sensor signal conditioning.

Key Features & Advantages

• High Voltage Rating (630V): Enables direct placement on high-bias nodes without derating concerns, reducing component count in multi-stage voltage dividers.
• Strict ±1% Capacitance Tolerance: Enhances circuit repeatability in precision timing or resonant applications, minimizing production tuning steps.
• Class-1 C0G/NP0 Dielectric: Delivers near-zero capacitance change over temperature (-55°C to +125°C) and low loss for high-frequency noise suppression.

Frequently Asked Questions

1. Q: What makes GRM31C5C2J103FWA3L different from a standard X7R 630V MLCC?
   A: Unlike X7R, the C0G/NP0 dielectric in this part provides essentially flat capacitance vs. voltage and temperature, crucial for high-precision analog and power filter networks.
2. Q: Is GRM31C5C2J103FWA3L 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, so you can order exactly what you need for pre-production validation.
