MLCC GCJ31BR72J103KXJ1L

What is GCJ31BR72J103KXJ1L MLCC?

The GCJ31BR72J103KXJ1L is a SMD capacitor manufactured by Murata. Key specs include 10000pF capacitance, 630V rating, X7R dielectric, and ±10% tolerance. RoHS compliant, it is designed for high-voltage decoupling and filtering in space-constrained circuits.

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

Typical Applications & Why This Part Fits

• Power supply input/output filtering: The 630V rating provides robust margin against voltage spikes in DC-DC converters and industrial PSUs, while the 1206 body handles higher ripple currents.
• Automotive infotainment noise suppression: X7R stability over -55°C to +125°C ensures consistent 10000pF capacitance under engine bay temperature variations, reducing EMI in CAN bus lines.
• Base station RF decoupling: The low-profile 1206 SMD package minimizes parasitic inductance, enabling clean bypass at GPS/LTE frequencies while withstanding transient overvoltages.

Key Features & Advantages

• High voltage rating (630V): Offers 3× derating safety margin over standard 250V parts for 48V telecom systems, preventing premature breakdown.
• Stable X7R dielectric: Maintains ±15% capacitance change across temperature range, ensuring predictable filter cut-off frequencies in harsh environments.
• 1206 package with ±10% tolerance: Solder joint reliability is enhanced by the larger terminations, while tight tolerance allows consistent BOM matching for production runs.

Frequently Asked Questions

1. Q: What makes GCJ31BR72J103KXJ1L different from a standard 1206 MLCC?
   A: Its 630V rating is far above typical 50V–100V equivalents, enabling direct placement on high-side power rails without series stacking.
2. Q: Is GCJ31BR72J103KXJ1L 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.
