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 �lters offers an optimized �lter range for enhanced performance AC and DC applications , in same compact size (KK, LL, NN types) All �lters provide an exceptional conducted attenuation performance, based on chokes with high permeable core material. FN 2090 two-stage �lters are designed for noisy applications requiring excellent �lter performance. The higher inductivity offers increased attenuation performance with the same form factor as FN 2060 and FN 2080 series. All FN 2090 �lters can be delivered with optional surge pulse protection (Z type). FN 2090 �lters are also available as singlestage �lters (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. FN2090Z-10-06, FN2090BZ-20-08). The different letters code the used Cy values in the �lter type (A = 0.47nF; K = 22nF; L = 33nF; N = 100nF; as the FN2090 is a dual stage �lter 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%

About Novapart

Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.

Learn more →

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Request a quote →

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
