US Patent:

6401329, Jun 11, 2002

Filed:

Dec 21, 1999

Appl. No.:

09/471622

Inventors:

Joel J. Smejkal - Columbus NE
Steve E. Hendricks - Columbus NE

Assignee:

Vishay Dale Electronics, Inc. - Columbus NE

International Classification:

H01C 1728

US Classification:

29619, 29621, 338293, 338308, 338314

Abstract:

A surface mount resistor includes an elongated piece of resistive material having strips of conductive material attached to its opposite ends. The strips of conductive material are separated to create an exposed central portion of the resistive material therebetween. According to the method the resistive strip is attached to a single co extensive strip of conductive material and a central portion of the conductive material is removed to create the exposed central portion of the resistive strip.

Assignee:

Vishay Dale Electronics, Inc. - Columbus NE

International Classification:

H01C 1728

US Classification:

29619, 296101, 29620, 338293, 338308, 338314

Abstract:

A surface mount resistor is formed from an elongated resistive body having first and second terminal ends and a raised center portion formed therebetween. The raised center portion includes slots in its edges which form a serpentine current path through the raised center portion of the resistor. A dielectric surrounds and encapsulates the raised center portion and an electrically conductive material coats the first and second terminal ends. The method for manufacturing involves utilizing an elongated ribbon which is of unitary construction and which is formed to create a carrier strip and a raised center portion for the resistors ultimately to be formed.

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.
