A resistor crossed by a line marked with a temperature sign.
Also known as: NTC symbol, PTC symbol, Temperature-dependent resistor
A thermistor is a resistor whose value changes with temperature, marked by a diagonal line ending in a small theta or the letters t. A sign next to the marking says which way it moves: negative for one falling with heat, positive for one rising.
Denotes a resistor deliberately sensitive to temperature, used for sensing or for inrush limiting.

Carries a sign next to its marking distinguishing a negative temperature coefficient device, whose resistance falls as it warms, from a positive one.
