What is Feedthrough Capacitor ?
The feedthrough capacitor is a three-terminal capacitor that is used to reduce high frequencies. The feedthrough capacitor, unlike regular three-terminal capacitors, is directly installed on the metal panel, resulting in a lower grounding inductance and a negligible effect on the lead inductance. As a result, the feedthrough capacitor provides good filtering.
Where can Feedthrough Capacitor Use?
Signals, data lines, and AC power lines, telecommunications equipment, microwave filters, industrial computers, and composite circuit filter components are all examples of where feedthrough capacitors and other filters are employed. A feedthrough capacitor on the computer’s CPU high-speed data bus, for example, can successfully reduce noise, while a feedthrough capacitor on the transmitter can effectively suppress interference.
