Line filters with PMEC toroidal chokes

Line filters are set up as passive low-pass, which cause the reflection of the interference energy to the interference source. Our common mode toroidal chokes with Y-capacitors are used for asymetric interference suppression. Our toroidal iron powder chokes with X-capacitors are used for symetric interference suppression.
