NTC Thermistor Symbol Characteristic Curve – A typical NTC thermistor gives most precise readings in the temperature range of -55 o C to 200 o C. However some specially designed NTC thermistors are used at absolute zero temperature (-273.15 o C) and some can be used above 150 o C.The figure below shows … See more As already discussed, temperature dependence of a resistor is defined by its temperature coefficient. According to this, the thermistors are classified into two categories based on the type of temperature … See more The Thermistor works on a simple principle: Change in temperature of the Thermistor, leads to a change in its resistance. How … See more PTC Thermistors can be actually broadly classified into two categories based on their applications.
