Abstract
A lead-through type filter used in a dc line for removing noises is disclosed. The lead-through type filter having angular elements according to the present invention includes a case to be used as an external grounding terminal. A central conductive line supplies a dc power and serves as IN/OUT terminals. At least one angular filtering element made of an angular ceramic stock is accommodated within the case. One side electrode is attached on a face of the ceramic stock and is electrically connected to the case . Another side electrode is attached on another face of the ceramic stock and is electrically connected to the central conductive line . An epoxy resin is filled into the interior of the case . Instead of the conventional lead-through type capacitor, polygonal capacitors are used in the present invention, and therefore, the capacitance control becomes easy, while the errors can be minimized. Further, the voltage withstanding characteristic is improved, and the workability is also improved during the manufacture.
