AC EMI RFI Line Filter Circuit

Product Description

An EMI suppression filter is an electronic component for providing electromagnetic noise suppression for electronic devices and is used in conjunction with shields and other protection

This filter only extracts and removes components that can cause electromagnetic noise from electric currents that are conducted through wiring.

Inductors are essentially tiny electromagnets that are able to hold energy in a magneticfield as electric current is passed through it, thereby reducing total voltage. 

The capacitors used in EMI filters are called shunting capacitorswhich redirect current in a specific rangehigh frequencyawayfrom a circuit or component.
