The ther- mistor’s resistance is changed by the amount of heat generated by the power dissipated by the element. Accuracy is limited in most applications only by the readout device.See Figure 1. a few typical applications. 43 Temperature Compensation NTC thermistors are effective in offsetting the effect of temperature on other circuit components. PTC thermistor applications make use of the characteristics inherent in their com-position. However, some thermistor applications depend upon significant "self-heating" to raise the body temperature of the thermistor well above the ambient temperature, so the sensor then detects even subtle changes in the thermal conductivity of the environment. Switching thermistors are a very useful form of electronic component.
