EMI Filters

EMI filters suppress disruptive frequencies in cables and electronics by minimizing electromagnetic interference. Often called common mode noise filters, the devices cut off frequencies in the range of megahertz to gigahertz without blocking the main electrical signal. EMI filters work in mobile phones, HDMI and USB connectors, household appliances, digital cameras, devices with LCD screens, audio players, telematics control units, and electrical power transmission lines. Each EMI filter currently sold by Littelfuse incorporates ESD protection to minimize electrostatic discharges.
