Manganese-zinc ferrites as compared to nickel-zinc have smaller losses.
Ferrite cores CUT type. Materials: P1, P2, P3, HQ8H, HQ2K, HQ2KA
Ferrite cores ETD type. Materials: P1, P2, P3
Ferrite cores RID type. Materials: P1, P2, P3, R5K
Nickel-zinc ferrite cores have a higher electrical resistance than the manganese-zinc.
