Abstract:
1. A reduced profile, reduced cost form-less surface mount inductive device adapted for mass terminated solder operations comprising: a shaped ferrous core element having first and second elements adapted for mating to one another, said first and second elements forming a winding channel therein when so mated, said elements further forming an aperture communicating with said channel; a bonded wire winding having a plurality of turns and disposed at least partly within said channel, said winding further comprising at least two ends which are routed though said aperture; and a terminal array comprising a substantially planar bottom surface disposed proximate to said core and having a plurality of electrically conductive terminals associated therewith, said plurality of electrically conductive terminals protruding from said bottom surface and adapted for surface mating of said terminals to corresponding traces or pads disposed on the substantially planar surface of a PCB, said at least two ends of said winding being in electrical communication with ones of said terminals; wherein said inductive device includes no former or bobbin for said winding, said absence of said former or bobbin reducing the required size and cost of said shaped ferrous core as compared to device having said former or bobbin; and wherein said bonded wire winding does not protrude below said substantially planar bottom surface of said terminal array, thereby allowing for said mass termination of said at least two ends to said ones of said terminals.
