Toroid Ferrite Core EMI/RFI Suppressor, 18mm
| Toroid Data Sheet | Not Available. |
These Toroid Ferrite cores are useful for suppressing EMI/RFI. Applications range from audio/video equipment wiring, R/C installations, and much more.
Outside diameter is 0.7 inch (18mm) and inside diameter is 0.36 inch (9mm). This is an ideal size for standard gauge R/C cables. A tough white conformal coating helps reduce breakage.
For effective common mode EMI/RFI suppression all you need to do is wrap several turns of cable around the bobbin shaped core (more turns = more suppression). These aren't effective in every electrical noise situation, but they are the first line of defense when EMI/RFI problems are encountered.
The photo below shows a typical example of a standard gauge (26 AWG) 3-wire R/C servo cable that has a Toroid installed on it.
