These RFI EMI snap-on ferrite suppressor choke cores can be used for reduction or elimination of radio frequency interference from such sources as AM or FM radio stations, Ham and Amateur radio, CB radio, fluorescent lights, electric motors, switching power supplies, computers, etc.
The best way to use these is to clamp them to each and every wire entering and leaving the equipment that is being interfered with or (if possible)  the equipment that is generating the interference. Snap on chokes should be used very close to the equipment (wrap wire near equipment). Also to be installed on speaker wire close to speakers. Not all interference comes through the wires, sometimes it enters the equipment directly. Interference can only be reduced or eliminated if it arrives through wires entering or leaving equipment being interfered with. Each additional wrap of wire is like adding another choke. Multiple chokes are often necessary to reduce or eliminate interference. Use trial and error method to see which wires are receiving the interference and snap these chokes on those wires.
These interference suppressor cores are reusable. Made by TOKIN, ESD-SR-15 inside hole size is 0.25"

on ALARM panel wires (this works especially good but you should run ALL
of
the alarm panel wires through chokes), I use multiple chokes here.

luorescent light noise, switching power supply noise.
For tough cases and maximum interference reduction wrap as many turns as possible and use multiple chokes
BALUN or RF choke for Ham (amateur) Radio, snap multiple chokes (as per Phil Salas, AD5X tests)
THESE ARE NOT RETURNABLE IF THEY DO NOT WORK FOR YOU!
Why? Some boneheads try to use these for LED headlights, etc and have NO IDEA what they are doing, so they blame these ferrites. I WILL NOT PAY FOR RETURN SHIPPING OR GIVE ANY REFUNDS! If you claim these are defective, I WILL FIGHT THAT ALL THE WAY and you will be banned from any future purchases!
