Abstract
An inductor includes an inductor body having a top surface and a first and second opposite end surfaces. There is a void through the inductor body between the first and second opposite end surfaces. A thermally stable resistive element positioned through the void and turned toward the top surface to forms surface mount terminals which can be used for Kelvin type sensing. Where the inductor body is formed of a ferrite, the inductor body includes a slot. The resistive element may be formed of a punched resistive strip and provide for a partial turn or multiple turns. The inductor may be formed of a distributed gap magnetic material formed around the resistive element. A method for manufacturing the inductor includes positioning an inductor body around a thermally stable resistive element such that terminals of the thermally stable resistive element extend from the inductor body.
