Standard Performance Single-Phase Filters FN2020

General Purpose AC/DC EMI Filter


General Purpose AC/DC EMI Filter

  • Rated currents from 1 to 60 A
  • High differential-mode attenuation
  • Optional medical version (B type)
  • Optional safety version (A type)

Features and Benefits

FN 2020 filters are designed for easy and fast chassis mounting
FN 2020 B versions without capacitors to earth comply to 1MOP for ME (medical equipment) acc. IEC 60601-1 
FN 2020 A versions with low capacitance to earth for safety critical applications with necessity for low leakage currents
All filters provide a general purpose conducted attenuation performance, based on chokes with high saturation resistance and excellent thermal behavior
FN 2020 filters can be used to cover a broad range of usage and they offer a good size/amperage ratio
FN 2020 filters are also available as two- stage filters (FN 2060, FN 2070 series) for more noisy environment
Various terminal options allow you to select the desired connection style
