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.
