Thermistors What is a thermistor? A thermistor is a temperature-sensing element composed of sintered semiconductor material which exhibits a large change in resistance proportional to a small change in temperature. Thermistors usually have negative temperature coefficients which means...

ZERO-POWER RESISTANCE The zero-power resistance is the dc resistance value of a thermistor measured at a specified temperature with power dissipated by the thermistor low enough that any further decrease in power will result in not more than 0.1% (or one tenth of the specified measurement tolerance...

Show More

Current-time characteristic: The current-time characteristic is the relationship at a specified ambient temperature between the current through a thermistor and time, upon the application or interruption of voltage to it. Dissipation constant (D.C. or delta ): The dissipation constant is the ratio...
