MLCC GRM55DR7LV334KW01K

What is GRM55DR7LV334KW01K MLCC?

The GRM55DR7LV334KW01K is a high-voltage SMD capacitor manufactured by Murata. Key specs include 0.33µF capacitance, 630V rating, X7R dielectric, and ±10% tolerance with a 2220 case size. RoHS compliant, it is designed for reliable decoupling and filtering in power-intensive circuits.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 630V rating and 0.33µF value provide effective ripple suppression in high-voltage power modules, while X7R ensures stable capacitance across -55°C to +125°C.
• Automotive On-Board Chargers (OBC): With 2220 footprint and robust X7R dielectric, this MLCC withstands high board stress and temperature cycles common in electric vehicle charging stations.
• Base Station Power Supplies: Low equivalent series resistance (ESR) from the multilayer structure minimizes heat generation during continuous 630V operation, ideal for RF power amplifiers.

Key Features & Advantages

• High Voltage (630V): Allows direct use in 400V bus rails without derating, reducing component count.
• X7R Dielectric: Offers ±15% capacitance change over temperature, balancing stability and volumetric efficiency for a 0.33µF/630V part in 2220.
• 10% Tolerance: Tighter than general-purpose X7R (±20%), enabling precise filter cutoff frequencies in sensitive analog circuits.

Frequently Asked Questions

1. Q: What makes GRM55DR7LV334KW01K different from a standard X7R MLCC?
   A: It combines a 630V rating with 0.33µF capacitance in a 2220 package—a rare high-voltage density combination not available in lower-cost 500V series.
2. Q: Is GRM55DR7LV334KW01K 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 for this Murata MLCC.
