Abstract

본 발명은 공통모드 및 정상모드 노이즈에 대한 영향을 소거하는 충분한 노이즈 소거효과를 나타내는 초크코일을 제공한다. 초크 코일은 2개의 보빈, 각각의 보빈의 둘레에 감겨 있는 한쌍의 권선, 그의 한쪽 측면에서 보빈의 통상동부에 각각 삽입되어 있는 제1자성체 코어 및 제2자성체 코어와 코어를 지지하기 위한 지지 수단으로 구성된다. 제1자성체 코어는 B자형으로 저투자율의 재료로 만들어진다. 제2자성체 코어는 D자형으로 고투자율의 재료로 만들어진다. 지지 수단의 상단면에 제공된 스페이서에 의해 코어 사이에 소정의 간극이 확보될 수 있다.
