Abstract
A resistor card for a fuel level sensor has improved resistance to corrosion and wear. The resistor card has a substrate with a resistive layer and a conductive layer. A nickel layer covers the conductive layer. A nickel-gold alloy layer covers the nickel layer. The nickel-gold alloy layer protects the conductive layer from sulfur corrosion and improves wear resistance.
