Thin film resistor having surface mounted trimming bridges for incrementally tuning resistance

Abstract:

A resistor assembly is disclosed and comprises a first conductive trace, a second conductive trace, and a plurality of trimming bridges that electrically couple the first conductive trace to the second conductive trace. The resistor assembly also comprises a thin film resistor electrically coupled to the first conductive trace. The first conductive trace, the second conductive trace, the plurality of trimming bridges, and the thin film resistor are all part of a surface mounted layer of the resistor assembly. The plurality of trimming bridges are each removable to increase a resistance of the thin film resistor.
