The feedthrough capacitor is a three-terminal capacitor, but compared with the ordinary three-terminal capacitor, because it is directly mounted on the metal panel, its grounding inductance is smaller, and there is almost no influence of lead inductance. In addition, its input and output The terminal is isolated by a metal plate to eliminate high frequency coupling. These two characteristics determine that the through-core capacitor has a filtering effect close to the ideal capacitor.
