Toroidal ind., T50-2 core (iron powder, red, 0.5" dia.)
E680005
L4-L8,L10-L12
8
Toroidal ind., T50-10 core (iron powder, black, 0.5" dia.)
Note: One FT50-43 gray ferrite core, also 0.5" dia,, is supplied (see T4).
The T50-10 iron power cores have a shiny, black finish, while the
ferrite core is dull gray. Label the ferrite core to avoid confusing it with the
eight iron powder cores.
