9mm Snap-on Ferrite Clip

A 9mm Snap-on ferrite clip for keeping RF out of keyboards/mice and other Shack perhiperals. A few loops of a cable around these can work wonders on keyboard/mouse lock-ups and also reducing breakthrough on "Hi-Fi" speakers.  You can obviously use more than 1 on a cable if you have a particularly tricky RFI issue!

• 9mm inner diameter (does NOT fit RG213)
• 130-ohm @ 25MHz

If you plan on using snap-on ferrites on coaxial cable (especially at HF frequencies), it's advisable to use a proper 31-mix Fair-Rite core such as the Problem Solver... Or, for smaller cables, Aerial Parts of Colchester sell these.
