The two common types of ferrite cores are manganese-zinc ferrite and nickel-zinc ferrite cores. Compared to other types, ferrite cores have relatively low permeability, low saturation flux density, and low Curie temperature. Their biggest advantage is their high electrical resistivity, which helps ...
