Abstract

본 발명은 전자파 잡음 제거용 칩형 캐패시터에 관한 것으로, 내부전극 재질은 적게 사용하지만 신호선의 일부분으로 사용되는 내부전극과 접지에 연결되는 내부전극에 의해 정전용량을 결정하는 유효전극 면적은 같으므로 정전용량의 감소는 없음 주파수가 높아질수록 소자의 등가직렬저항을 많이 감소시킬 수 있어 전력손실에 의한 열의 발생과 온도상승 억제하는, 또한 고주파에서 접지에 연결되는 내부전극의 인덕턴스를 감소시킴과 동시에 고주파에서 임피던스도 작게하여 컴퓨터, 통신기기등 전자기기의 신호선에서 많은 문제되고 있는 고주파 잡음을 제거하는 전자파 잡음 제거용 칩형 캐패시터에 관한 것이다.The present invention relates to a chip type capacitor for eliminating electromagnetic noise, wherein the internal electrode material is used less, but the effective electrode area for determining the capacitance by the internal electrode used as part of the signal line and the internal electrode connected to the ground has the same capacitance. There is no decrease in the frequency. The higher the frequency, the more the equivalent series resistance of the device can be reduced, thereby suppressing heat generation and temperature rise due to power loss, and reducing the inductance of the internal electrode connected to the ground at high frequency and at the same time high impedance The present invention relates to a chip type capacitor for eliminating electromagnetic noise, which removes a lot of high frequency noise that is a problem in signal lines of electronic devices such as computers and communication devices.
