Ferrite Toroid
TVI Elimination

(ICH) FT-240-43
2.4" outside diameter, 1.4" inside, 1/2" wide. Material 43 is usable from DC-200 MHz, is most often found in 1-30 MHz circuits with best Q range from DC-5 MHz. Z=58 ohms @ 25 MHz, 108 ohms @ 100 MHz. To use as TVI filter, pass AC line cord, coax, data cable or speaker wire through toroid as many passes as possible. The more, the better. We have one on the network cable at each workstation throughout our entire warehouse. Surges from nearby lightning hits were taking out the network cards. I haven't lost one since the "roids".
