Understanding RFI Power Line Filters
What Is a Power Line Interference Filter?
A power Line interference filter is a primary tool available to the designer of electronic equipment to control conducted RFI both into the equipment (potential equipment malfunction) and out of the equipment….
Since the largest component of leakage current is usually from the power line filter, it is prudent to set a maximum leakage current limit for the filter itself……..
