Power NTC thermistor can be a cost effective device to limit the amount of inrush current in a switching power supply or other devices when the power is first turned on. Power NTC thermistor limits surge current by functioning as a power resistor which drops from a high cold resistance to a low hot resistance when heated by the current flowing through it.
Inrush-current limiters power NTC thermistor protect circuits from undesirably high currents, suppressing high inrush current surges, while its resistance remains negligible low during continuous operation. Thanks to their low resistance in the operating state, Power NTC thermistor have a considerably lower power dissipation than the fixed resistors frequently used for this application.

NTC thermistor can be assembled in housing in a variety of configurations for temperature sensing, measurement, detection, indicator, monitoring and control. Thermistor temperature sensor probe assemblies can conveniently attach to or be an integral part of any system to monitor or control temperature.
Thermistor Temperature Sensor Probe assembly, in ring lug terminal for surface temperature sensing, housed in copper, threaded stainless steel, ABS for immersion sensor, for HVAC, air conditioner, freezer, food processing, industrial control application.

Since all metals used for coil windings have a positive temperature coefficient of resistance, NTC thermistor are especially useful for compensating resistance changes in devices subjected to temperature variations.
Due to the high temperature coefficient of the thermistor as opposed to the low temperature coefficient of the copper, full compensation can be achieved by using a thermistor– resistor network. This network adds less than 15% to the total impedance of the circuit. Compensation of transistor amplifiers, crystal oscillators, etc. can be achieved by using similar methods.
