Manganese-zinc ferrites as compared to nickel-zinc have smaller losses.
Ferrite cores ETD type. Materials: P1, P2, P3
Ferrite cores EC type. Materials: P1, P2, P3
Ferrite cores UU type. Materials: P1, P2, P3
Nickel-zinc ferrite cores have a higher electrical resistance than the manganese-zinc.
DIP bobbins, coils are used as frames for the installation of ferrite cores.
