    Recommended EMI Filters

    NAC-16-472

    High voltage pulse noise type: NAP series
    Low Leakage Current type: NAM series
    *Use of an EMI/EMC filter is recommended when a power supply is connected with several devices so that additional filtering is necessary.
    *Make sure that your final application will meet the required EMC standard by measuring the EMI level of the power supply used together with an EMI/EMC filter.
