The device being discussed, I think, is more properly called a
split ferrite bead. A toroid is sort of a doughnut made of
ferrite material or powdered iron and the cable or wire is wound
through it several times. There are ferrite beads that slip over
a wire but they have to be put on before plugs or connectors are
installed. The advantage of split beads, of course, is that they
can be applied to a cord or cable and snapped together like the
Radio Shack item, or the two halves are sometimes held together
with tape.
Unless they come in different sizes, the split beads I got from
Radio Shack would not fit a heavy air conditioner cord. However,
there are large split ferrite beads that can fit RG8-sized cable
available from such places as Amidon Associates, The Wireman and
Ppalomar Engineers.
