NTC Thermistor Application Note
In this application note, we will explore the various uses and considerations of NTC thermistors. NTC thermistors are temperature-sensitive resistors that have a negative temperature coefficient, meaning their resistance decreases as the temperature rises. This characteristic makes them ideal for temperature measurement and compensation in a wide range of applications.
