TDK Product Features

TDK's feedthrough components are used for high-frequency interference suppression of electrical equipment. The present product range is used, for instance, in telecom applications, industrial lasers or medical devices. By means of broadband interference suppression up to a GHz range, feedthrough components prevent the transmission of interference from outside of the device to inside of it and vice versa. Feedthrough filters are constructed in PI circuit. They consist of two capacitors with same capacitance and one inductive serial element. As a result of the concentric construction of the components a high insertion loss in a broadband frequency area up to more than 1 GHz, high isolation resistances and compact designs can be achieved.
