attenuation
Optional medical versions (B type)
Optional safety versions (A type)
Optional enhanced performance versions
Optional overvoltage protection (Z type)
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.
The higher inductivity offers increased
attenuation performance with the same form
factor as FN 2060 and FN 2080 series.

** To compile a complete part number, please replace the -.. with the required I/O connection style.
** For surge pulse protection, please add Z (e.g. FN2090Z-10-06, FN2090BZ-20-08). The different letters code the used Cy values in the filter type (A = 0.47nF; K
= 22nF; L = 33nF; N = 100nF; as the FN2090 is a dual stage filter each letter stands for one stage of Cy)
** Maximum leakage under usual AC operating conditions (acc. IEC 60939-3). Note: if the neutral line is interrupted, worst case leakage could reach twice this
level. Leakage current for DC application is 0mA
*** Tolerances apply: Inductance: -30/+50%, Capacitance: ±20%, Resistance: ±10%
