Recent Work

  •
    30kW Coupled (2 winding) Inductor, 112uH, 14kHz (EC Custom Model 217057)
    Intended for High Power Filter applications in a 30kW converter, this 2-coil inductor is rated 112uH @ 700V square wave (14kHz); peak current reaches 230A. The customer needed a complete re-design of an existing part from another manufacturer in order to reduce excessive losses. Consists of multiple layers of 0.012" copper foil with Mylar insulation assembled on a 50ALL ferrite core that was modified in-house to fit. (Custom Model 217057)
  • Common Mode Filter Choke - 500uH 20kHz 100A
    This custom filter choke is foil-wound on multiple FU93 ferrite cores with Class H (180C) insulation (part number 209087).
  • Sinewave CCR Output Filter Inductor
    This custom CCR output filter inductor boasts 0.7 mH @ 90A, 50Hz with 14App ripple @ 10kHz, high temperature 220C insulation, 0.010" copper foil windings on Metglas® wound amorphous metal C-core.
