The effects of sizes of polycrystalline ferrite ring cores on magnetic characteristic - complex initial permeability (CIP) are studied. In the case of MnZn ferrite under uncontrolled microstructure (grain sizes) clear size effect is observed: dispersion of smaller core sizes is at higher frequencies and vice versa. In the case of controlled microstructure (NiZn ferrite) no size effects were observed.
