What is a thermistor?
Thermistors are thermally sensitive resistors whose resistance changes with temperature. There are two main types;
- NTC – In NTC thermistors, the resistance drops when the temperature increases
- PTC – In PTC thermistors, the resistance rises when the temperature increases
NTC Thermistors are widely used for temperature measurement as their RT (Resistance-Temperature) characteristic is well defined and can be readily programmed into PICs etc. NTCs are available in a multitude of formats, whether they are glass bead, surface mount, rigid or flexible leads, they provide an array of solutions to simplify the assembly and reduce production costs.
PTC Thermistors are often used as solid-state fuses/thermal switches. Their simple step-function RT characteristic allows them to be easily incorporated into circuitry. In the case of motor protection thermistors, several can be used in series to protect each phase of a 3-phase motor.
