Features and benefits
FN 2090 two-stage filters are designed for easy and
fast chassis mounting.
The FN 2090 filters are also available as B versions
with no Y-capacitors for medical applications as well
as A versions with low capacitance for safety critical
applications with a requirement for low leakage
currents.
FN 2090 filters offers an optimized filter range for
enhanced performance AC and DC applications , in
same compact size (KK, LL, NN types)
All filters provide an exceptional conducted
attenuation performance, based on chokes with
high permeable core material and excellent thermal
behaviour.
FN 2090 two-stage filters are designed for noisy
applications requiring excellent filter performance.
The higher inductivity versus amperage offers
increased attenuation performance with the same
form factor compared to FN 2060 and FN 2080 filter
series.
All FN 2090 filters can be delivered with optional
surge pulse protection (Z type).
FN 2090 filters are also available as singlestage filters
(FN 2030 series).
Various terminal options allow you to select the
desired connection style.
Typical applications
Electrical and electronic equipment
Consumer goods
Household equipment
Building automation
Industrial applications
Machinery
Medical equipment
Electronic data processing equipment
Office automation and datacom equipment
Various noisy applications requiring high filter
performance
