MLCC GR442QR73D221KW01L

What is GR442QR73D221KW01L MLCC?

The GR442QR73D221KW01L is a high-voltage SMD multilayer ceramic capacitor manufactured by Murata. Key specs include 220pF capacitance, 2kV rated voltage, X7R dielectric, 1808 package with ±10% tolerance. RoHS compliant, it is designed for reliable decoupling and filtering in high-stress environments.

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

Typical Applications & Why This Part Fits

• DC‑DC converter snubbing: The 220pF capacitance and 2kV rating allow it to dampen high‑frequency switching noise without exceeding voltage margins.
• Base station power amplifiers: X7R stability over temperature ensures consistent filtering performance in telecommunication transmitters.
• Industrial motor drives: The 1808 footprint handles HV transients, while the low capacitance value limits inrush current during start‑up.

Key Features & Advantages

• High breakdown voltage: 2kV rating provides extra safety margin in circuits prone to surges and flashovers.
• Stable X7R dielectric: Capacitance change within ±15% over –55°C to +125°C suits outdoor and under‑hood environments.
• Compact 1808 size: The small footprint saves board space while still offering 220pF, ideal for dense power sections.

Frequently Asked Questions

1. Q: What makes GR442QR73D221KW01L different from a standard 220pF capacitor?
   A: It is specifically rated for 2kV in a 1808 package, whereas standard MLCCs of this capacitance are often limited to 50V or 100V.
