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  
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.
The higher inductivity offers increased attenuation performance with the same form factor as FN 2060 and FN 2080 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.
