KYOCERA AVX TRAFIM Series high-voltage power film capacitor for dc filtering applications up to 6,000Vdc are widely used for its high energy density and controlled self-healing technology, which ensures proven-safe, high-reliability performance over 100,000-hour lifetimes at rated voltage and 80°C hot spot temperature — and up to 240,000 hours with appropriate derating — in a wide range of high-voltage industrial, military, research, traction, power transmission, and renewable energy applications. Product’s case size is 66% smaller than the initial offering, while maintaining the same extended lifetime expectancy and impressive failure rate of <100FIT, as well as increasing the maximum specific energy to 495J/L at operating temperatures up to 95°C. Product has been qualified to the IEC 61071, IEC 61881, IEC 61373, IEC 60068-2, and EN-45545 standards. Product is suitable for use in an expansive range of global, cross-market dc filtering applications, including dc links, power converters, drives, traction systems, windmills, substations, energy storage, and pulse discharge, resonant filtering, and active correction devices.
