31 Material is Fair-Rite’s most broadband suppression material. The high permeability allowed by Manganese-Zinc construction extends strong attenuation performance all the way down to 1MHz while still allowing for high impedance to 300MHz and beyond. In Snap-it form, these cores can be quickly and easily added to existing conductors without the need for disassembly or removal of terminations. Fair-Rites precision manufacturing process allows for near-solid core attenuation performance without significant upsizing of the ferrite core.
