13mm Snap-on Ferrite Clip

A 13mm 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.  Can be used on RG58/RG213 coaxial cable.  You can obviously use more than 1 on a cable if you have a particularly tricky RFI issue!

• Max 13mm inner diameter, 36mm length

We also sell a 5mm diameter version.

This generic brand has similar properties to 43-mix - 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.

A note about ferrites, mixes and RFI/Noise QRM :
There is no guarantee that any ferrite will cure noise on your radio, and it may not be possible to "filter" any noise from your neighbour's equipment that is radiating in the air (eg: solar-panels, greenhouse/fish-pond equipment etc).  "Ferrite-on-cable" is the best approach, and significant gains can usually be obtained by getting your own house in order before tackling external sources.  Experimentation with placement, turns and quantity of ferrites is key - there is never a one-size-fits-all solution!
