Special Application

High-Frequency Metallized Film Capacitors

Dry-construction capacitors built on self-healing metallized polypropylene film — oil-free and maintenance-free, with copper busbar terminals for direct busbar mounting. Engineered for the resonant circuits of IGBT/MOSFET solid-state high-frequency power supplies, carrying kiloamp-class high-frequency current in a compact envelope. Available with water cooling or conduction cooling, plus optional tap-selectable models that cover several capacitance steps in a single unit.

Applications

  • Solid-state high-frequency power supply resonant circuits
  • High-frequency induction heating & melting
  • New energy converter equipment
  • Marine power systems
  • Aerospace high-reliability applications
