DATASHEET
Two-Stage Filters FN 2090
Multi-stage AC/DC EMI Filter with Excellent Attenuation Performance
Rated currents from 1 to 30 A
Approvals
Two-stage filter
Very high differential and common-mode
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.
Performance indicators
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.

** 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. FN 2090Z-10-06, FN 2090BZ-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 0 mA
