Features and benefits
FN 2020 filters are designed for easy and fast chassis
mounting
FN 2020 filters are also available as B versions
without Y-capacitors for medical applications as well
as A version with low capacitance for safety critical
applications with necessity for low leakage currents
All filters provide a general purpose conducted
attenuation performance, based on chokes with
high saturation resistance and excellent thermal
behavior
FN 2020 filters can be used to cover a broad range
of usage and they offer a good size/amperage ratio
