Harnessing the Power of Feedthru Filters: Advanced EMI and RFI Suppression Solutions

A feedthru filter, also known as a feedthrough filter or a feed-through capacitor, is an electrical component used to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) in electronic circuits. It is a type of passive filter that is designed to block high-frequency noise and allow low-frequency signals to pass through.

The feedthru filter is constructed by inserting a capacitor element inside a metal housing with feedthrough pins that enable the filter to be connected to other circuit components. The metal housing acts as a shield to prevent external interference from entering the circuit.


Understanding Feedthru Filters and Their Role in EMI and RFI Suppression

Feedthru filters are commonly used in power supplies, data communication systems, and other electronic devices where EMI and RFI must be suppressed. They are also used in medical devices and military equipment where high reliability and performance are critical.


Applications of Feedthru Filters in Various Industries


The Shield Feedthru Filters can be used for all types of applications where signals need to be feed through a shielded wall.
