ABSTRACT:
A resistor device of simple construction particularly adapted for use as a precision, low ohmic value resistor. The terminal leads are axially aligned and extend outwardly from a molded housing. The inner end of each lead is shaped into a flat surface to facilitate the welding thereto of a resistor element and to minimize twisting of the embedded end of the lead. A radially extending disc shaped portion on each lead is adjacent the flat portion and is embedded in the molded housing to prevent axial movement of the embedded end of the lead. The embedded flat and disc shaped portions serve to minimize forces from acting on the weld joints to break the welds. The resistance element is free standing wire shaped into a serpentine configuration and embedded in the molded housing.
