Abstract
An improved surface mount resistor and method for making the same includes a body comprised of an elongated strip of electrically resistive material and a resistor terminal formed at each end of the resistive material. The resistive material is machined with a laser beam to create a current path having a desired resistance. The pattern cut is determined by partitioning the resistive material into a plurality of squares forming a current path through the resistive material with the correct resistivity. The resistive material is cut primarily with axial cuts so that the beam strength of the resistive material is maintained.
