Patent ID: 7002447

Claim:
A resistor card for a fuel level indicator system, comprising: a planar ceramic substrate having a first and second surface; an arc-shaped set of spaced apart conductor lines mounted on the first surface, the conductor lines each having a first end, a second end and a central portion; an arc-shaped resistive area overlying the central portion, the resistive area in electrical contact with the electrical lines; an encapsulant covering the arc-shaped resistive area; an arc-shaped solid conductor—continuous—base mounted on the first surface and spaced from the conductor lines; wherein a first nickel layer covers the conductor lines and the conductor base, wherein a second nickel layer covers the first nickel layer, and wherein an electroplated nickel and palladium alloy layer covers the second nickel layer, the nickel and palladium alloy layer having a composition based on a total composition comprising 15.0 to 25.0 weight percent nickel and 75.0 to 85.0 weight percent palladium.
