Abstract: An advanced electronic signal conditioning circuit and associated housing elements. In one embodiment, the circuit comprises a plurality of coupled inductors and capacitors arranged in a signal filtering configuration which achieves enhanced voice- and DSL-band performance through the use of complex-impedance modeling during the circuit design phase. Free-standing and fixed device housings are also disclosed. Methods for manufacturing the aforementioned components are also described.

Abstract: A blind hole pot core transformer comprised of a base member having a toroidal channel with a central post and a cover member also having a toroidal channel with a central post. A bobbin winding is positioned within a cavity defined by the toroidal channels of the base and cover members with a core comprised of the central posts of the base and cover member positioned within an opening in the bobbin winding. A compressible alignment member is positioned within an opening formed on outer mating surfaces of the central posts of both the base and cover members to retain the base and cover members in a desired orientation with respect to each other. The compressible alignment member has a cross-sectional area that is greater than the openings in the base and cover members so that any gap between the alignment member and the inner walls of at least one of the openings is eliminated thereby facilitating alignment between the central posts comprising the core of the device.

Abstract: An electronic component mounting holder for surface mounting of an electronic component having a plurality of tape leads, includes a non-conducting three dimensional rectangular frame having vertical peripheral walls formed of nonconducting material for receiving an electronic component having a plurality of tape leads, the peripheral walls having a top peripheral edge and a bottom peripheral edge, a support ledge extending inward from inner surface of said peripheral wall for supporting an electrical component, a coil formed of foil windings having leads formed by extensions of said foil windings, a plurality of tape lead receiving areas formed in at least two sides of said bottom peripheral edge, said receiving areas each positioning a tape lead for surface bonding to a conductor on a PC board, a plurality of lead receiving recesses formed in corresponding sides of said top peripheral edge for receiving an outermost end of a tape lead, and a retainer for mounting in engagement with latch means in said frame
