What is a feedthrough capacitor? Type of feedthrough capacitor? The through-core capacitor, because it is coated with a metal layer on the porcelain tube, forming two poles inside and outside. Because the tube is empty, it is called a feedthrough capacitor. It is a three-terminal capacitor, but compared with ordinary three-terminal capacitors, because it is directly [...]

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. [...]
