Yesterday I have a brief introduction of temperature coefficient of resistance (short for TCR), which means when the temperature of the resistor changes 1 centigrade, the resistance value changes accordingly, and the unit is ppm/℃. There are negative temperature coefficient, positive temperature coefficient and critical temperature coefficient that resistance occurs at a particular temperature.
Resistors have parameters, what relationships are among them? A brief introduction of resistance and temperature will be given. Actually the conductor resistance has relationship to temperature. Temperature coefficient of resistance has positive temperature coefficient and negative temperature coefficient, which is related to resistor materials. The resistance of pure metal resistors rises with increasing temperature. When the temperature rises １℃, resistance will increase several parts per thousand. The resistance of carbon and insulator decreases with increasing temperature. The relationship between the semiconductor resistance and temperature is big, when the temperature slightly increases, resistance decreases dramatically. Some alloys such as konstantan alloy and manganese bronze resistance has little relationship with temperature changes.
Because of the temperature is an important factor for resistors, it is necessary to learn more about your application when choose a correct resistance. Microhm Electronics provides and manufacturers precision foil resistors. According to different requirements, Microhm provides different suitable resistors and services.
