Abstract
Resistance material comprising a mixture of metal oxidic compounds, metal oxides, a permanent binder and a temporary binder, the resistance-determining component consisting of at least one component having the formula M.sub.x Sr.sub.1-x Rh.sub.2 O.sub.4-4.5 in which M is selected from Pb and Bi and wherein 1/2>x>0. By combining this component with a material having an opposite TCR, a resistor having a very small TCR is obtained. This resistor is formed by firing this resistance material on a substrate.
Claims8
A resistance material comprising at least one compound having the formula M.sub.x Sr.sub.1-x Rh.sub.2 O.sub.4-4.5 wherein M is selected from the group consisting of Pb and Bi, and wherein x is between 0 and 1/2.
A resistance material comprising a mixture of a permanent binder, a temporary binder, and a resistance-determining component, said resistance-determining component comprising at least one compound having the formula M.sub.x Sr.sub.1-x Rh.sub.2 O.sub.4-4.5 wherein M is selected from the group consisting of Pb and Bi, and wherein x is between 0 and 1/2.
A resistor comprising a resistor body provided with leads, said resistor body comprising a substrate bearing a resistance material as claimed in claim 9 or 10, said resistor body having been produced by heating the substrate and the resistance material so as to remove the temporary binder and form a coherent resistive layer.
