Abstract
A functionally adjusted thick-film thermistor-resistor network having an accurately preselected electrical resistance and change of electrical resistance with temperature, and a method of forming the same. The network features a thermistor and/or a conductor segment contacting the thermistor having a plurality of parallel paths. Some of the paths preferably provide a different resistance change with temperature than others. A selected number of the parallel paths are severed during functional testing to adjust the thermistor to a preselected change in network resistance with change in temperature. The resistor is functionally adjusted in the usual manner to obtain the selected total network resistance value at room temperature.
