KYOCERA AVX is celebrating the release of its 1,000th TRAFIM Series high-voltage power film capacitor for DC filtering applications up to 6,000VDC. TRAFIM Series capacitors are widely renowned for their 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. Since introducing the first TRAFIM Series capacitors to market in 1990, KYOCERA AVX has produced more than 365,000 of the now-1,000 unique TRAFIM Series part numbers, representing more than 20,000 tons of capacitors deployed in various global industries with zero catastrophic failures.

TRAFIM Series capacitors were initially developed in 1987 for use in the traction industry, but the series has since undergone continuous design and performance improvements that have significantly expanded its utility and application. For example, the integration of FIM technology, which features high-temperature polypropylene film coated with metallized aluminum and impregnated with vegetable oil, enables the series' benign failure mode, which exclusively consists of capacitance losses, effectively prevents potential explosions resulting from avalanche effect, and ensures proven-safe and reliable high-energy-density performance over extended product lifetimes up to 240,000 hours. Additional improvements include the release of a new case size that 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. Over time, the series has also been qualified to the IEC 61071, IEC 61881, IEC 61373, IEC 60068-2, and EN-45545 standards.

Due to these and other significant design and performance improvements over the last several decades, TRAFIM Series capacitors are now ideal 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.
