More Information
Summary:The present invention relates to a coil electronic component which includes: a body which has an inner coil with at least one withdrawal part embedded therein, and includes a mixture of a magnetic material and a reins; and an external electrode which is arranged on the outer side of the body and is electrically connected to the withdrawal part of the inner coil. The body includes a core region of a region wound with the inner coil and a margin region which is adjacent to the outer surface of the inner coil. The resin content of the mixture filled in the body is different in accordance with a position in the body. Accordingly, the present invention can minimize the reduction of inductance. 본 발명은 적어도 하나의 인출부를 가지는 내부 코일을 매설하며 자성 물질과 수지의 혼합물을 포함하는 바디, 및 상기 바디의 외부면에 배치되며 상기 내부 코일의 인출부와 전기적으로 연결되는 외부전극을 포함하고, 상기 바디는 상기 내부 코일에 의해 감아지는 영역의 코어 영역과, 상기 내부 코일의 외표면과 인접하는 마진 영역을 포함하고, 상기 바디 내 충진되는 상기 혼합물의 수지의 함량은 바디 내 위치에 따라 상이한 코일 전자부품에 관한 것이다.
