Ferrite Cable Clamp Filter

The ferrite core function resembles that of an inductor but the ferrite frequency response deviates from this functionality at high frequencies.

Ferrite cable clamp filter.

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. Initial test results of ferrite rings showed poor performance compared to clamps when a single wire was passed through a ring. Mouser offers inventory pricing datasheets for ferrite clamp on cores. 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 rings are a convenient way for a large cable to achieve multiple turns and high exposure to the ferrite material. This does not mean that ferrite rings are a poor choice.

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.

Before mounting the clamp filter noise was emitted at a broad frequency band from 100 to 600 mhz. 0730 clamp filter connected to the power cable. Ferrite clamps vs ferrite rings. Ferrite clamp on cores are available at mouser electronics.
