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

Typical Applications & Why This Part Fits

• Power Supply Output Filtering: The 450V rating and stable X7T dielectric make it ideal for smoothing rectified DC in industrial power supplies, reducing ripple without excessive derating.
• DC-DC Converter Snubber Circuits: Its 0.47µF capacitance and low equivalent series resistance help suppress voltage spikes in high-voltage converters, protecting downstream components.
• Automotive On-Board Chargers: The 2220 footprint provides reliable mechanical strength, while the X7T temperature characteristic ensures minimal capacitance drift from -55°C to +125°C, critical for EV charging modules.

Key Features & Advantages

• High Voltage Rating (450V): Enables direct use in 400V bus architectures without series stacking, simplifying layout and reducing component count.
• X7T Dielectric Stability: Offers tighter capacitance change (±15%) over temperature than standard X7R, ensuring consistent filtering performance across extreme conditions.
• Compact 2220 Form Factor: Saves PCB space compared to through-hole alternatives while handling high ripple currents, ideal for dense board designs.

Frequently Asked Questions

1. Q: What makes GR355DD72W474KW01L different from a standard X7R MLCC?
   A: It uses Murata’s X7T dielectric with improved temperature stability (±15% vs. ±15% for X7R over -55°C to +125°C) and is specifically rated for 450V in a 2220 package, whereas many X7R parts at this voltage are limited to lower capacitance values.
2. Q: Is GR355DD72W474KW01L 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 flexibility for low-volume needs.
