  • POWER RESISTOR
    Publication number: 20090085715
    Abstract: A resistor includes first and second opposite terminations, a resistive element formed from a plurality of resistive element segments between the first and second opposite terminations, at least one segmenting conductive strip separating two of the resistive element segments, and at least one open area between the first and second opposite terminations and separating at least two resistive element segments. Separation of the plurality of resistive element segments assists in spreading heat throughout the resistor. The resistor or other electronic component may be packaged by bonding to a heat sink tab with a thermally conductive and electrically insulative material. The resistive element may be a metal strip, a foil, or film material.

  • Surface mount electrical resistor with thermally conductive, electrically insulative filler and method for using same
    Patent number: 7190252
    Abstract: 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.

  • Precision resistor tube feeder
    Patent number: 6669435
    Abstract: A system, method, and apparatus, for resistor tube feeding is disclosed. A tube magazine comprising a length of tubing and adapted for receiving precision resistor cores and compressed air is disclosed. The tube magazine may be connected to a laser spiraller and a terminal welder. The process of filling the tube magazine may be electronically controlled.
