Ferrite Cable Clamp Filter

Ferrite beads are used as a passive low pass filter by converting rf energy to heat by design contrast this with inductors which by design minimize conversion of rf energy to heat offering a high impedance to rf.

Ferrite cable clamp filter.

20ea inner 7mm 0 28inch cable wires clip emi filter ferrite bead clamp rf choke ferrite ring noise cancel ferrite core black. The geometry and electromagnetic properties of coiled wire over the ferrite bead result in an impedance for high frequency signals attenuating high frequency emi rfi. Ferrite rings are a convenient way for a large cable to achieve multiple turns and high exposure to the ferrite material. 20 pcs snap on ferrite core cord ring rfi emi noise filter suppressor cable clip for 3 5mm 5mm 7mm 9mm 13mm diameter cable black 4 1 out of 5 stars 142 9 99 9.

Initial test results of ferrite rings showed poor performance compared to clamps when a single wire was passed through a ring. As in the case of the previous test after winding the exclusive cable twice around the clamp filter noise was relatively reduced by 5 to 10 db. Unfortunately ferrite beads also called a ferrite choke ferrite clamp ferrite collar emi filter bead or even a ferrite ring filter can be a bit of a mystery. 20ea inner 7mm 0 28inch cable wires clip emi filter ferrite bead clamp rf choke ferrite ring noise cancel ferrite core black 4 4 out of 5 stars 9 11 96 11.
