Ferrite cores

Charles Darley

Hi all

I have been reading through the threads and have found that there are
several Ferrite cores suggested fortunately I have them all ...
FT 37 - 43
T 50 - 6
T 50 - 2

BUT can anyone sugest and explanation for using several different
ones when the T 50 - 2 is listed for frequencies 1 to 30MHz and I
would have thought could be used at all location.

The T50-6 is listed for 10 to 50 MHz and the FT37-43 is listed for 2
