Abstract
Bonded soft ferrite using injection molding is expected to have applications, because it conforms with the trend toward miniaturization and complication of the shape of electronic devices, At present, the permeability of bonded soft ferrite is too low for it to have practical applications, because of the mixture of ferrite powder and resin. Increasing its permeability is thus an important problem to be solved. To this end, we used kneading and injection molding to produce bonded soft ferrites mixed with nylon resin and several kinds of NiCuZn ferrite powder with various size distributions, and then measured the soft magnetic properties and electric resistance of bonded NiCuZn ferrites.
