Abstract
A low profile surface mountable toroid inductor. The apparatus features a one step molded housing which includes a cover and opposing mounting legs. The housing is molded in a liquid crystal polymer. The length of wire that provides the turns on the toroid also serves as the mounting pads as each end of the wire that is left exposed during the housing molding process is then wrapped around its corresponding leg to provide a mounting pad. The apparatus is able to achieve a thickness that is less or equal to 1.5 mm by eliminating the thickness of a prefabricated cover. Further, a flat surface can be molding into the housing so that the apparatus can be positioned with “pick and place” techniques. Also, the apparatus can be configured so that it can be mounted upside down as well. A blind hole is provided that orients the toroid within the mold and serves to prevent any gate vestige from protruding beyond the mounting surface as well as reducing mechanical stress on the press due to the different coefficients of thermal expansion of the respective components.
