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

Typical Applications & Why This Part Fits

• Power supply snubber circuits: The 630V rating and C0G/NP0 stability ensure reliable spike suppression without capacitance drift under high voltage stress.
• High-frequency resonant tanks: C0G/NP0 dielectric offers ultra-low ESR and stable capacitance across temperature, critical for precise tank tuning.
• Automotive DC-DC converter filtering: The 1206 footprint provides robust solder joint reliability, while ±5% tolerance maintains consistent noise attenuation.

Key Features & Advantages

• 630V High-Voltage Rating: Enables direct use in 400V+ bus rails and high-side circuitry without derating concerns.
• C0G/NP0 Dielectric: ±30ppm/°C temperature coefficient guarantees capacitance stability from -55°C to +125°C.
• ±5% Tight Tolerance: Reduces design guard bands for critical timing and filter cut-off frequency accuracy.

Frequently Asked Questions

1. Q: What makes GRM31B5C2J681JW01L different from a standard 1206 capacitor?
   A: Its 630V rating is significantly higher than typical 50V or 100V 1206 MLCCs, and the C0G dielectric ensures near-zero voltage coefficient.
2. Q: Is GRM31B5C2J681JW01L 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.
