In the field of power electronics, EMI filters are used to suppress and filter out unwanted high-frequency electromagnetic noise generated by the switching operations of power electronic circuits. Especially with ceramic EMI filters, the primary function of these components is to provide a low-impedance path for unwanted high-frequency noise while allowing the desired power signal to pass with minimal impedance. EMI filters act as low-pass filters, attenuating high-frequency noise and preventing its propagation. Learn More
