Fair-Rite Suppression Product Selector Guide

Conducted EMI can occur over a wide range of frequencies, from as low as 1MHz to several GHz. Fair-Rite offers a complete line of suppression ferrites that cover a gamut of frequencies. If you are late in the design phase & fixing the EMI at the board level isn’t feasible, we also offer clamp-on cores for interconnecting cable assemblies.

  • Predictable and repeatable impedance to enhance signal integrity
  • Snap-It cores available in a wide range of core sizes. Fair-Rite has catalog products available to support a wide range of cable diameters – from 3.5mm (.137”) up to 101.6mm (4”)
  • UL94V0 rated polypropylene snap-it case
  • Available in FR75 ferrite blend – superior low frequency performance
  • Available in a wide range of ferrite blends to cover 150KHz to 1 GHz
  • Engineering Kits available in all snap its including 31 Material, 43 Material, 46 Material, 61 Material and 75 Material
