MLCC GCJ31CR7LV473KW01K

What is GCJ31CR7LV473KW01K MLCC?

The GCJ31CR7LV473KW01K is a high-voltage SMD capacitor manufactured by Murata. Key specs include 0.047µF capacitance, 630V rating, X7R dielectric, 1206 case size, and ±10% tolerance. RoHS compliant, it is designed for reliable decoupling and filtering in demanding power circuits.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 630V voltage rating provides ample headroom for high-voltage rails found in industrial power modules, while the 0.047µF value effectively attenuates switching noise.
• Automotive On-Board Charger Snubber: X7R dielectric ensures stable capacitance across -55°C to +125°C, critical for suppressing ringing in 400V bus systems within EV chargers.
• Base Station Power Amplifier Bias: The 1206 footprint supports adequate creepage distance for 630V operation, and the ±10% tolerance keeps bias decoupling predictable across production lots.

Key Features & Advantages

• 630V DC Rating: Enables direct use on high-voltage DC links without series stacking, simplifying layout and reducing component count.
• X7R Dielectric Stability: Capacitance change within ±15% over the full temperature range ensures consistent filter performance under thermal stress.
• 1206 Industry-Standard Package: Compatible with automated pick-and-place lines and reflow soldering, supporting high-volume assembly with repeatable quality.

Frequently Asked Questions

1. Q: What makes GCJ31CR7LV473KW01K different from a standard 1206 MLCC?
   A: This part is specifically designed for 630V operation in a 1206 body, whereas standard X7R 1206 MLCCs typically top out at 100V or 200V. The enhanced dielectric thickness and termination design allow safe high-voltage operation.
2. Q: Is GCJ31CR7LV473KW01K 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-turn small-batch flexibility for engineering samples.
