ABSTRACT:
Disclosed is a resistor comprising a nonconductive substrate on which is disposed a rectangularly-shaped coating of resistive material having a negative TCR. Oppositely disposed along the longer sides of the coating is a pair of elongated, parallel strips of resistive material having a positive TCR. Electrical connection is made to the opposed ends of the coating and to an end of each strip. The strips and electrical connections are so disposed that at low temperatures, current flow is predominantly across a relatively wide, short path in the coating between the strips, and at higher temperatures, current flow is predominantly along a longer, narrower path in the coating which is parallel to the strips.
