NTC Thermistor Applications & OEM Selection Guide
In this guide How NTC thermistors work Common NTC thermistor applications Benefits and design limits OEM selection checklist How NTC thermistors work An NTC thermistor is a temperature-sensitive resistor whose resistance decreases as its temperature rises. A circuit converts the resistance change into a temperature reading or uses the change to control another function. The sensor element alone does not define system accuracy: the resistance–temperature (R/T) curve, measurement circuit, thermal contact, calibration and operating conditions all matter. There is no single temperature range, tolerance or construction that applies to every NTC. TDK’s NTC application notes identify selection inputs such as
