Manganese-zinc ferrites as compared to nickel-zinc have smaller losses.
Ferrite cores PM type. Materials: P1, P2, P3
Ferrite cores ETD type. Materials: P1, P2, P3
Ferrite Toroidal cores. Materials: H10K, H8K, H6K, H5K, P1, P2, P3
Nickel-zinc ferrite cores have a higher electrical resistance than the manganese-zinc.
