Laminar resistor having low temp. coefft. - consisting of metal foil glued to insulating carrier

Very thin metal foil (1-10 mu) is glued to an insulating carrier, etched to the desired electric resistance and provided with wire leads. The metal foil (pref. a Ni-Cr alloy) and the carrier (Al2O3, sodium silicate glass or borosilicate glass) are chosen in such a manner that the difference between...

Zusammenfassung:Very thin metal foil (1-10 mu) is glued to an insulating carrier, etched to the desired electric resistance and provided with wire leads. The metal foil (pref. a Ni-Cr alloy) and the carrier (Al2O3, sodium silicate glass or borosilicate glass) are chosen in such a manner that the difference between their coeffts. of linear thermal expansion is 26-66 x 10-7 degrees C-1. The temp. coefft. of the electric resistance is within the range plus-or-minus 3 x 10-6 degrees C-1.
