EMI filter capacitor feedthrough made in china

The core of the EMI filter capacitor feedthrough is a disc-shaped multilayer or tubular ceramic capacitor. Like other ceramic items, it will be damaged by sudden temperature changes, mechanical vibration and excessive voltage. When installing the feed-through filter on the board surface, care must be taken to minimize various stresses when welding the guide pin of the filter and shaping.

EMI filter capacitor feedthrough characteristics and applications

1) Welded EMI filter
Welded EMI filter is the most ideal product for small installation space;
Application: mainly used for filtering signals, data lines and AC power lines; telecommunication equipment, transmission equipment, microwave filters, industrial computers, and composite circuit filter components
