MLCC GR355DD7LQ474KW01K

What is GR355DD7LQ474KW01K MLCC?

The GR355DD7LQ474KW01K is a high-voltage SMD capacitor manufactured by Murata. Key specs include 0.47µF capacitance, 630V rating, X7T dielectric, and 2220 case size with ±10% tolerance. RoHS compliant, it is designed for reliable filtering and energy storage in demanding power circuits.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 0.47µF / 630V rating provides ample bulk capacitance for smoothing high-voltage rails while the X7T dielectric ensures stable capacitance over temperature.
• Snubber Circuits in Power Supplies: The 2220 footprint allows excellent heat dissipation, and the ±10% tolerance suits snubber timing requirements without excessive derating.
• Industrial Motor Drive Bus Decoupling: The 630V withstand voltage safely handles transient spikes in 3-phase rectified lines, and the X7T characteristic minimizes capacitance loss under DC bias.

Key Features & Advantages

• High Voltage Handling: 630V rating enables direct placement on high-voltage buses without series stacking, reducing PCB area and component count.
• X7T Dielectric Stability: Offers tighter capacitance variation over temperature than X7R, ensuring consistent performance in thermally dynamic environments.
• Compact 2220 Form Factor: Balances high capacitance density with robust termination strength, suitable for automated assembly and reflow soldering.

Frequently Asked Questions
