Patent number: 9502171Abstract: 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.Type: GrantFiled: March 10, 2015Date of Patent: November 22, 2016Assignee: Vishay Dale Electronics, LLCInventors: Thomas T. Hansen, Jerome J. Hoffman, Timothy Schafer, Nicholas J. Schade, David Lange, Clark Smith, Rod Brune

Patent number: 7864015Abstract: A flux-channeled high current inductor includes an inductor body having a first end and an opposite second end and a conductor extending through the inductor body. The conductor includes a plurality of separate channels through a cross-sectional area of the inductor body thereby directing magnetic flux inducted by a current flowing through the conductor into two or more cross-sectional areas and reducing flux density of a given single area. The inductor body may be formed of a first ferromagnetic plate and a second ferromagnetic plate. The inductor may be formed from a single component magnetic core and have one or more slits to define inductance. The inductor may be formed of a magnetic powder. A method is provided for manufacturing flux-channeled high current inductors.Type: GrantFiled: April 26, 2006Date of Patent: January 4, 2011Assignee: Vishay Dale Electronics, Inc.Inventors: Thomas T.
