This existing non-magnetic alloy has a TCR of ± 930 ppm/°C. Within Q1 2016, a new resistive element material will be used for applications that require a more stable TCR. This new material is a magnetic stainless steel with a TCR of ± 365 ppm/°C, which will provide superior performance in dynamic braking resistors, testing load banks, motor control, and other applications requiring minimal change in resistance as the elements increase in temperature. For additional information on how to design for nominal resistance within a grid resistor design, please consult the following technical article: http://www.vishay.com/doc?21044.
