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
FN 2020 filters are also available as two- stage filters
(FN 2060, FN 2070 series) for more noisy
environment
Various terminal options allow you to select the
desired connection style
Typical applications
Electrical and electronic equipment
Consumer goods
Household equipment
Medical equipment
Office automation equipment
Datacom equipment
