Assignee:

Vishay Dale Electronics, Inc. - Columbus NE

International Classification:

H01C017/00

US Classification:

296101, 29611, 29612, 29613, 29620, 29827, 29832, 29850, 156242

Abstract:

A high power resistor includes a resistance element with first and second leads extending out from the opposite ends thereof. A heat sink of dielectric material is in heat conducting relation to the resistance element. The heat conducting relationship of the resistance element and the heat sink render the resistance element capable of operating as a resistor between the temperatures of −65 C. to +275 C. The heat sink is adhered to the resistance element and a molding compound is molded around the resistance element.

International Classification:

H01C 1/148

US Classification:

338332, 338329, 296101

Abstract:

A resistor includes a substantially cylindrical resistive element having a resistance of less than about 1 mΩ, a substantially cylindrical first termination electrically connected to the resistive element and a second termination electrically connected to the resistive element. The substantially cylindrical first termination is hollow to allow for accepting a connection such as from a battery cable. In addition there may be sense leads present on the resistor. A method of forming a substantially cylindrical resistor includes forming a hollow cylindrical resistor body by rolling a flat sheet comprising a resistive element and a first termination and a second termination joined on opposite ends of the resistive element.

International Classification:

H01F 27/29

US Classification:

336192

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.
