What does NTC do?
Just so, how does a NTC thermistor work?
There are two types of thermistors: Negative Temperature Coefficient (NTC) and Positive Temperature Coefficient (PTC). With an NTC thermistor, when the temperature increases, resistance decreases. Conversely, when temperature decreases, resistance increases. This type of thermistor is generally used as a fuse.
Additionally, what is difference between NTC and PTC? Difference 1: NTC: Negative temperature coefficient thermistor, the higher the temperature, the lower the resistance. PTC: Positive temperature coefficient thermistor, the higher the temperature, the higher the resistance.
Besides, what happens with the resistance in an NTC component?
NTC Thermistors are non-linear resistors, which alter their resistance characteristics with temperature. The resistance of NTC will decrease as the temperature increases. The manner in which the resistance decreases is related to a constant known in the electronics industry as beta, or ß. Beta is measured in °K.
What are NTC thermistors made of?
Many NTC thermistors are made from a pressed disc, rod, plate, bead or cast chip of semiconducting material such as sintered metal oxides. They work because raising the temperature of a semiconductor increases the number of active charge carriers it promotes them into the conduction band.
