    Tips: EMI filter important technical parameter- insertion loss
    The most important technical parameter of EMI filter is the capability to restrain interference, normally referring to Insertion Loss. It’s the ratio between the powers transmitting from interference source to load before connecting filter and after connecting filter, and it uses dB as unit. EMI filter insertion loss is relevant with network parameter of filter network and impedance of source end and load end. To avoid filtering useful signal, insertion loss should be specified carefully. No matter what EMC standard is in the military use or civil use, it has clear specification for equipment or sub system power line conducting interference level. The difference value between estimated or tested EMI conducting interference level and standard conducting interference level is the minimum insertion loss of requested EMI filter. Yet, it is impossible in actual project to do EMC test for different single equipment, then analyze its conducting interference characteristic, and design the filter satisfying with requirement. The suitable filter only needs to be selected according to actual status.

    Existing reviews of Power Line Filter, EMI/RFI, 30A, 3 phase
    Good filter and works well.
    Good product. Bought one EMI line filter for a trial. I installed for 3D printer to cut down the noise from the power line and it does the job. Works well as expected, and I will buy more.
