Deciding on Thermistors

Out of all the different types of resistors, one of the most widely used is a thermistor. A thermistor is basically a resistance temperature detector that resists based on temperature. The thermally sensitive resistor's main job is to create and maintain exact and predictable changes in electronic resistance despite consistent changes in temperature. A thermistor will change electrical resistance even when the body of the devices is unchanged. If using a thermistor within circuitry, especially circuits that have insufficient power, the body of the thermistor will follow temperature. 

Thermistors come in two main types, and these types cannot be used interchangeably. An NTC thermistor is a to adequately resist an decrease within temperature. This allows the thermistor to protect itself from overvoltage conditions. A PTC thermistor works in an opposite fashion. These types of thermistors are designed to help increase resistance when temperature changes. NTC thermistors are normally made out of rods, plates, beads, or pressed discs. A PTC thermistor is created with doped polycrystalline ceramics.
