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

Typical Applications & Why This Part Fits

• High-Voltage DC-DC Converters: The 2kV rating and 100pF capacitance provide essential snubber and bypass filtering for switching nodes, reducing EMI and voltage spikes.
• RF Coupling & Decoupling: Low capacitance of 100pF and X7R stability enable clean signal coupling in antenna matching networks and RF amplifiers operating near high voltage rails.
• Power Supply Input Filters: The 1808 footprint supports board density while the ±10% tolerance ensures predictable frequency response in mains-connected power entry modules.

Key Features & Advantages

• 2kV Rated Voltage: Enables safe operation in industrial and automotive high-voltage circuits without derating anxiety.
• X7R Dielectric: Maintains capacitance stability over -55°C to +125°C, crucial for thermal cycling environments.
• Compact 1808 Package: Balances high-voltage creepage requirements with PCB space savings for dense layouts.

Frequently Asked Questions

1. Q: What makes GR442QR73D101KW01L different from a standard 100pF MLCC?
