Filters of the NFK4135-30A42 series are used to suppress circuit-bound interferences in three-phase AC power lines with neutral conductor.
Interference pulses or interference voltages are dampened independently from their point of origin.
To improve the filter effect they are designed with 2 stages and have a high insertion loss on a wide frequency range.
High insertion loss over a broad frequency range
Using aluminium enclosure in order to improve the heat conduction
