Patent number: 7190252Abstract: An electrical resistor is provided with a resistive element and terminations extending from opposite ends of the resistive element. The terminations are folded under the resistive element, with a thermally conductive and electrically insulative filler being sandwiched and bonded between the resistive element and the terminations. The terminations provide for mounting of the resistor to an electronic circuit assembly. The intimate bond between the resistive element, filler and terminations allow for enhanced dissipation of heat generated in the use of the resistive element, so as to produce a resistor which operates at a lower temperature, and improves component reliability.Type: GrantFiled: February 25, 2005Date of Patent: March 13, 2007Assignee: Vishay Dale Electronics, Inc.Inventors: Clark L.
