Abstract

본 발명은 칩형 3단자 전자파장애 방지 필터에 관한 것으로 그 기술적인 구성은, 페라이트 소자(2)의 필터 본체부(3) 좌우 양측에 코일 권선홈(6)(6')을 개재하여 단자부(4)(5)를 형성하며, 상기 코일 권선홈(6)(6')으로 동선코일(11)이 권선되어 필터 본체부(3)와 양측 단자부(4)(5)에 도포된 전극(8'), (9)(9')과 전기적으로 연결 접속토록 하고, 상기 필터 본체부(3)의 중앙에는 칩형 콘덴서(l2)를 삽입 고정하는 한편, 상기 페라이트 소자(2)의 하측 전극을 제외한 전체를 수지로서 몰딩한 수지 몰딩부(l3)를 형성토록 하는 것이다. 이에 따라서, 페라이트 소지를 칩형으로 구성하여 리드선이 필요없이 기판상에 용이하게 실장시킬 수 있으며, 페라이트 소자에 권선되는 동선 코일의 턴수에 의해 인덕턴스값은 자유롭게 가변시킬 수 있는 것이다.The present invention relates to a chip-type three-terminal electromagnetic interference prevention filter, the technical configuration of the terminal portion (4) through the coil winding grooves 6, 6 'on both the right and left sides of the filter main body (3) of the ferrite element (2). 5), and the copper wire coil 11 is wound around the coil winding grooves 6 and 6 ', and the electrode 8' is applied to the filter main body 3 and the both terminal portions 4 and 5, respectively. ), (9) and (9 ') to be electrically connected to each other, and the chip-shaped capacitor l2 is inserted into and fixed to the center of the filter main body 3, except for the lower electrode of the ferrite element 2. To form the resin molding portion l3 molded with resin. Accordingly, the ferrite element can be formed in a chip shape so that it can be easily mounted on a substrate without the need for a lead wire, and the inductance value can be freely changed by the number of turns of the copper wire coil wound on the ferrite element.
