아몰퍼스 코어는 합금을 리본처럼 만들어서 이를 적당한 폭으로 절단하여 테이프 감듯이 돌돌 말아서 만든 합금코어입니다.
아몰퍼스 코어는 뛰어난 DC-Bias 특성으로 인하여 SMPS 및 산업용 기기에서 인덕터 및 리액터로 사용되고 있습니다.

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
