ABSTRACT:
A low cost, low profile, small size and high performance electronic device for use in, e.g., electronic circuits where a transformer, inductor, or mixer is required. In one exemplary embodiment, the device includes a “binocular” ferrite core comprising a plurality of core apertures and windings. The core is shaped with one or more channels which are at least partly plated (metallized) so as to allow bonding of the winding terminations directly to the core. The placement of these plated areas allows simplified surface mounting. The plated areas also obviate a termination header, thereby simplifying the manufacture of the device and reducing its cost. Methods for manufacturing the device are also disclosed.
