Amorphous Choke Cores

Amorphous Core is an alloy core made by turning an alloy into a ribbon shape, cutting into appropriate width, and rolling as if to wind a tape.
Amorphous Core is used for inductors and reactors in SMPS and industrial devices due to the excellent DC-bias characteristics.

Applications
  • Output choke coil for SMPS
  • Choke coil for DC/DC converter
  • PFC choke for UPS
  • Choke coil for adapter and battery charger
  • PFC choke for PDP TV set
  • PFC choke for inverter circuit
