General Purpose EMI Filter
Approvalsn Rated currents from 1 to 60A
n High differential-mode attenuation
n Optional medical versions (B type)
n Optional safety versions (A type)
Typical applications
n FN 2020 filters are designed for easy and
fast chassis mounting.
n 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.
n All filters provide a general purpose
conducted attenuation performance, based
on chokes with high saturation resistance
and excellent thermal behavior.
n FN 2020 filters can be used to cover a
broad range of usage and they offer a good
size/amperage ratio.
n FN 2020 filters are also available as two-
stage filters (FN 2060, FN 2070 series) for
more noisy environment.
n Various terminal options allow you to
select the desired connection style.
n Electrical and electronic equipment
n Consumer goods
n Household equipment
n Medical equipment
n Office automation equipment
n Datacom equipment
