What is the difference between PTC and NTC thermistor?

 

For an NTC thermistor, as temperature increases, resistance decreases. For a PTC thermistor as temperature increases, resistance increases.

 

 

Characteristic PTC Curve Of The PTC Thermistor Chip


The typical resistance curve of a semiconductor as a function of temperature is called PTC curve. The initial resistance of the PTC first decreases slightly with increasing temperature until the lowest resistance value Rmin is reached. Now the actual PTC behavior begins as the resistance increases non-linearly up to the nominal temperature Tc. At this point, also known as Curie temperature, the PTC’s resistance increases significantly. The operating range of the PTC extends from the nominal temperature Tc to the maximum final temperature Te, where hardly any current flows. The maximum temperature of a PTC depends on its ceramic composition and can therefore be determined in advance. Another characteristic of the PTC is its inrush current. As the resistance of the PTC is at its lowest value in Rmin, a particularly large amount of current can flow there, causing it to undergo an increased inrush current for a few seconds each time it is switched on.
