Shaped Cores

  • Characteristics: More than 10 different shaped cores and combinations
    Special shaped cores can increase storage capacity
    Suitable for small dimensions, large currents designs
    Suitable for high difficulty winding and assembly type inductors
  • Applications: Solar cell inverters, Boost inductors,
    Flyback transformers,
    Output chokes for SMPS,
    Small dimension DC/DC converters,
    PFC, AC Reactors for inverters.
