EMI Filters

onsemi EMI Filters feature LC, RC, and common-mode EMI filters for use in a wide variety of audio and data interfaces. The EMI is a radio frequency disturbance (800MHz to 2GHz) that affects an electrical circuit due to electromagnetic conduction from an external source. These onsemi EMI filters avoid the EMI by eliminating radio-frequency (RF) noise and maintaining signal integrity.
