CMF Industrial www.vishay.com Vishay Dale TEMPERATURE COEFFICIENT CODES GLOBAL TC CODE HISTORICAL TC CODE TEMPERATURE COEFFICIENT E T-9 25 ppm/°C H T-2 50 ppm/°C K T-1 100 ppm/°C L T-0 150 ppm/°C N T-00 200 ppm/°C M M 300 ppm/°C LOAD LIFE SHIFT DUE TO POWER AND DERATING (AT +70 °C AND AT +125 °C) The power rating for the CMF parts is tied to the derating temperature, the heat rise of the parts, and the R for the load life performance. When the tables/graphs below are used together they show that when the parts are run at their higher power ratings, the parts will run hotter, which has the potential of causing the resistance of the parts to shift more over the life of the part.
