  • Patent number: 4837659
    Abstract: A discrete electromagnetic device in which the transformer/inductor function and a capacitive function are integrated is achieved by utilizing both the magnetic permeability and the dielectric constant of one or more soft ferrite layers. The device is comprised of a plurality of soft ferrite planar layers spaced apart in a stacked array. Between each soft ferrite layer is a metallic layer which forms one of the plates of the capacitor. A first and second set of apertures are defined through each of the planar ferrite layers. The first and second set of apertures are aligned among the plurality of ferrite layers so that a conductive element is led through one set of apertures to form a loop or coil. A similar conductive element or coil is led through the second set of apertures to form a second loop. The two loops thus serve as the secondary and primary of a transformer or alternatively as two inductors with the ferrite material acting as the magnetically permeable core.
