It's spelt "thermistor" actually. It's a temperature dependent resistor.

Temperature dependent resistor. Resistance changes in a predictable way as temperature changes.
PTC thermistors = positive temperature coefficient= resistance rises in some way as temperature rises. Some vary very linearly with temperature (metallic), and some switch from low resistance to very high resistance over a small temperature range (semiconductor).
NTC thermistor = negative temperature coefficient= resistance falls in some way as temperature rises.
