Features and benefits
FN 2090 two-stage filters are designed for easy and
fast chassis mounting.
FN 2090 B versions without capacitors to earth
comply to 1MOP for ME (medical equipment) acc.
IEC 60601-1
Performance indicators
FN 2090 A versions with low capacitance to earth
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.
FN 2090 two-stage filters are designed for noisy
applications requiring excellent filter performance.
Technical specifications
The higher inductivity offers increased attenuation
performance with the same form factor as FN 2060
and FN 2080 series.
