ABSTRACT:
An electrical resistor having a negative temperature coefficient for incremental resistance values has a resistance wafer with solderable coatings on opposite sides thereof and current lead elements soldered to the coatings, with the soldered ends of the lead elements being each coiled to form an annular eye, the soldering covering only the region of the eye and leaving the remainder of the coatings outside of the eye free of solder.
