This Product Selection Guide contains information to help select products in the EMI, Filter Kits category on DigiKey.com
EMI filters suppress noise in electric currents that are conducted through wiring such as power cables and conductor paths. A common mode choke is an EMI filter that blocks high frequency noise common to two or more data or power lines while allowing the desired DC or low-frequency signal to pass. Filter kits allow for experimentation with varying sizes and types of filters including chokes, ferrite disks, plates, beads and chips, transformers, cores, resonators, and saw filters.
