The ferrite core function resembles that of an inductor but the ferrite frequency response deviates from this functionality at high frequencies. 1 offer from 49 99.

Before mounting the clamp filter noise was emitted at a broad frequency band from 100 to 600 mhz. Initial test results of ferrite rings showed poor performance compared to clamps when a single wire was passed through a ring. Ferrite clamp on cores are available at mouser electronics. 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.
