ABSTRACT:
A highly coupled inductor includes a first ferromagnetic plate, a second ferromagnetic plate, a film adhesive between the first ferromagnetic plate and the second ferromagnetic plate, a first conductor between the first plate and the second plate, and a second conductor between the first plate and the second plate. A conducting electromagnetic shield may be positioned proximate the first conductor for enhancing coupling and reducing leakage flux. A method of manufacturing a highly coupled inductor component includes providing a first ferromagnetic plate and a second ferromagnetic plate, placing conductors between the first ferromagnetic plate and the second ferromagnetic plate, and connecting the first ferromagnetic plate and the second ferromagnetic plate using a film adhesive.
