NTC Negative Temperature Coefficient Thermistor is characterized by heat-sensitive semiconductor resistors whose temperature rises and resistance drops.
The resistance change of the NTC thermistor can be the result of self-heating through the change of the external surrounding temperature or the internal current flowing through it.
All negative temperature coefficient thermistors are made of metal oxide ceramic materials, which can be used to suppress instantaneous surge currents.
Negative temperature coefficient<\/strong>: When the temperature rises<\/strong>, the resistance value decreases<\/strong>, that is, the resistance value is inversely proportional to the temperature.<\/p>\n\n\n\n

Operation principle: Take the power supply as an example. At the moment when the power is turned on, the NTC has a higher resistance, so it will suppress the surge current for about 1 to 2 seconds. During this period of time, the internal resistance of the NTC will decrease due to the increase in temperature. Until the voltage drop across the NTC thermistor is negligible.<\/p>\n\n\n\n

\u25cfNTC thermistor, that is, negative temperature coefficient thermistor, its characteristic is that the resistance value decreases nonlinearly with the increase of temperature. NTC is generally divided into temperature measuring thermistor and power thermistor in the application. The NTC thermistor used to suppress surge refers to the power thermistor. NTC thermistor is a power-type thermistor specially designed for surge suppression.<\/p>\n\n\n\n
