Manganese-zinc ferrites as compared to nickel-zinc have smaller losses.
Ferrite Toroidal cores. Materials: H10K, H8K, H6K, H5K, P1, P2, P3
Ferrite cores FEY type. Materials: P1
Ferrite cores POT type. Materials: P1, P2, P3, HQ8H, HQ2K, HQ2KA
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.
