There are many potential applications for NTC thermistors. Their accuracy and stability make them highly useful for a wide range of purposes. These applications include temperature measurement, compensation, and control. NTC thermistor probes are generally used as resistance thermometers. 

Thermistors are temperature-sensing elements made of semiconductor material that has been sintered in order to display large changes in resistance in proportion to small changes in temperature. 

What is an NTC Thermistor Summary: Explains what an NTC thermistor is and its capabilities as a temperature sensor. Ametherm's NTC thermistors and probes are described, as well as the terminology used. 

There are several component options for inrush current limiting. The two most common alternatives are the use of NTC (Negative Temperature Coefficient) thermistors or various forms of active circuits. 

Peak Inrush Current occurs in one cycle = 564 Amps as measured on the scope. Practical Max Inrush Current occurs in 5 cycles = 188.0 Amps as measured on the scope. Input Voltage = 120VAC Ambient temperature = 80?C. Frequency = 60 Hz. Efficiency of transformer = 70%.
