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. 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.

Ferrite rings are a convenient way for a large cable to achieve multiple turns and high exposure to the ferrite material. Before mounting the clamp filter noise was emitted at a broad frequency band from 100 to 600 mhz. The measurement results are shown in figure 4.

Ferrite clamp on cores are available at mouser electronics. The ferrite core function resembles that of an inductor but the ferrite frequency response deviates from this functionality at high frequencies.

Initial test results of ferrite rings showed poor performance compared to clamps when a single wire was passed through a ring. 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. Mouser offers inventory pricing datasheets for ferrite clamp on cores. This does not mean that ferrite rings are a poor choice.
