US 7,843,309 B2 · Power resistor

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.
