Buyers requirements
The basic electrical characteristic of a thermistor is that its resistance value changes with temperature, and the temperature of the thermistor itself will change with the surrounding temperature or the self-heating caused by the current passing through the thermistor. In applications such as temperature measurement, control and compensation, the self-consumption of the thermistor is required to be kept to a minimum to avoid self-heating. When the ambient temperature remains the same, the resistance value of the thermistor is a function of the self-consumption power of the thermistor. In this case, the temperature of the thermistor rises to higher than the ambient temperature.
In some operating conditions the high temperature can be 100~200℃ resistance can be reduced to low current conditions under the dry resistance value in some applications can use the thermal contact resistance of its own heating characteristics. In the self-heating state, the thermistor is thermally sensitive to any condition that changes the thermal conductivity of the thermistor. If the heat dissipation speed can be ideally fixed, the thermistor is sensitive to the power input, so the thermistor is suitable for voltage level or power level control.
