The GR443QR73D222KW01L is a high-voltage SMD capacitor manufactured by Murata. Key specs include 2200pF capacitance, 2kV DC rating, X7R dielectric, ±10% tolerance, and 1812 case size. RoHS compliant, it is designed for stable operation in demanding power and industrial circuits.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Snubbers: The 2kV rating ensures reliable voltage spike suppression, while X7R stability maintains capacitance over temperature.
• Industrial Power Inverters: 2200pF at 2kV suits bus capacitor snubbing and EMI filtering in motor drives and high-voltage rails.
• LED Lighting Drivers: Compact 1812 footprint and robust X7R dielectric allow space-efficient, high-reliability decoupling in off-line drivers.

Key Features & Advantages

• 2kV DC Voltage Rating: Enables direct use in high-voltage power stages without series stacking, simplifying layout.
• X7R Temperature Stable Dielectric: Capacitance change within ±15% from -55°C to +125°C, ensuring consistent performance in harsh environments.
• Murata Quality & 1812 Package: Industry-leading manufacturing yields low failure rates, and the standard 1812 size eases pick-and-place assembly.

Frequently Asked Questions

1. Q: What makes GR443QR73D222KW01L different from a standard MLCC?
   A: Its 2kV rating is far above typical ≤100V chips, making it suitable for snubber and high-voltage filter circuits where standard MLCCs would fail.
