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. Ametherm specializes in NTC , or negative temperature coefficient, thermistors. NTC thermistors are one of the most used temperature sensors.
The resistor guide will explain you all about their characteristics, types and applications. Construction and properties. Basic Knowledge of Thermistors.
What is an NTC Thermistor ? Negative Temperature Coefficient Thermistor. NTC Thermistors are electronic components which reduce the resistance when the temperature increases. They work because raising the temperature of a semiconductor increases the number of active charge carriers - it promotes . Electronics Tutorial about the Thermistor which is a temperature sensing device that changes its physical resistance to changes in temperature. THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
THE PRODUCTS DESCRIBED HEREIN AND THIS . Aug However, PTC thermistors have a sort of tipping point and greatly change the resistance at some temperature. This makes the PTC thermistor a little harder to interface with.
