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

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 630V rating ensures reliable performance in high-voltage rails, while the 1000pF value provides essential high-frequency noise suppression without bulky through-hole parts.
• Power Supply Snubber Circuits: X7R dielectric offers ±15% capacitance change over -55°C to +125°C, making it suitable for snubber capacitors that must handle voltage spikes in switch-mode power supplies.
• Industrial Sensor Interface Protection: The 1206 package provides adequate creepage distance for 630V isolation, and the ±10% tolerance maintains accuracy in signal coupling or DC blocking applications.

Key Features & Advantages

• High Voltage Rating (630V): Enables use in circuits that demand robust insulation and reliability, reducing the risk of dielectric breakdown in power management designs.
• Stable X7R Dielectric: Maintains predictable capacitance over a wide temperature range, ensuring consistent filtering and decoupling performance in harsh environments.
• Compact 1206 Footprint: Balances board space savings with ease of assembly, allowing dense PCB layouts without sacrificing high-voltage capabilities.

Frequently Asked Questions

1. Q: What makes GRM31BR72J102KW01L different from a standard 1000pF capacitor?
   A: Its 630V rating is significantly higher than typical low-voltage MLCCs, enabling direct use in 48V or 400V bus filtering where standard 50V parts would fail.
2. Q: Is GRM31BR72J102KW01L 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 quick turnaround for urgent needs.
