MLCC GRM43DR72H224KW10L

What is GRM43DR72H224KW10L MLCC?

The GRM43DR72H224KW10L is a high-voltage SMD capacitor manufactured by Murata. Key specs include 0.22 µF capacitance, 500V rating, X7R dielectric, and 1812 case size (±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

• High-Voltage DC-Link Snubbers: With its 500V rating and X7R stability, this MLCC effectively suppresses ringing and transients in motor drives and inverters operating near 400V bus rails.
• Power Supply Output Filters: The 0.22 µF value provides adequate high-frequency noise attenuation while the 1812 footprint handles the thermal and voltage stresses common in AC-DC converters.
• Automotive On-Board Chargers: AEC-Q200 capable by design, the part’s robust construction supports the 500V stress and temperature cycles typical in EV charging port circuits.

Key Features & Advantages

• High Voltage with Small Footprint: 500V rating in a compact 1812 case reduces board space compared to larger through-hole or 2220 alternatives.
• X7R Temperature Stability: ±15% capacitance variation over -55°C to +125°C ensures predictable performance across wide operating ranges.
• Low ESR at High Frequencies: Murata’s proprietary ceramic process yields low equivalent series resistance, improving filtering efficiency above 1 MHz.

Frequently Asked Questions

1. Q: What makes GRM43DR72H224KW10L different from a standard X7R 1812 capacitor?
