MLCC GRM31A5C2J680JW01D

What is GRM31A5C2J680JW01D MLCC?

The GRM31A5C2J680JW01D is a SMD capacitor manufactured by Murata. Key specs include 68 pF capacitance, 630 V DC rating, C0G/NP0 dielectric, ±5% tolerance, and 1206 package size. RoHS compliant, it is designed for high-voltage filtering and coupling with ultra-stable capacitance over temperature and voltage.

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

Typical Applications & Why This Part Fits

• DC-DC converter snubber circuits: The 630 V rating and C0G/NP0 dielectric ensure minimal capacitance shift under high-voltage transients, providing reliable EMI suppression.
• High-frequency resonant tanks: 68 pF value combined with low ESR and excellent frequency stability makes it ideal for RF oscillator tank circuits and impedance matching networks.
• Industrial sensor interfaces: ±5% tolerance guarantees consistent timing in RC filters for signal conditioning, while the 1206 package offers robust solder joint reliability in vibration environments.

Key Features & Advantages

• C0G/NP0 Dielectric: Near-zero temperature coefficient (±30 ppm/°C) ensures capacitance remains constant from -55°C to +125°C, critical for precision analog circuits.
• 630 V High Voltage Rating: Built for applications where nominal 500 V parts risk derating; the 1206 body safely handles repeated high-voltage surges.
• ±5% Tight Tolerance: Eliminates the need for sorting or trimming in production, reducing assembly cost for high-volume designs.

Frequently Asked Questions

1. Q: What makes GRM31A5C2J680JW01D different from a standard 1206 C0G capacitor?
   A: Its 630 V voltage rating is significantly higher than typical 50 V or 100 V C0G parts, while maintaining the same 68 pF capacitance and ±5% tolerance – a rare combination for high-reliability designs.
2. Q: Is GRM31A5C2J680JW01D 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.
