Manganese-zinc ferrites as compared to nickel-zinc have smaller losses.
Ferrite cores FEY type. Materials: P1
Ferrite cores PEI type. Materials: P1, P2, P3
Ferrite cores RM type. Materials: H10K, H7K, H6K, 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.
