An NTC thermistor refers to a type of temperature-sensitive resistor whose electrical resistance decreases as the temperature rises. Commonly used in various electronic devices, NTC thermistors are crucial for temperature measurement, control, and compensation purposes. While "NTC thermistor" might be the most widely recognized term, several synonyms exist that represent the same concept. These include negative temperature coefficient thermistor, negative temperature coefficient resistor, temperature-sensitive resistor with negative temperature coefficient, and temperature-compensating resistor. These various synonyms help individuals better understand and communicate the concept of an NTC thermistor, regardless of the terminology used. Overall, they all refer to the same type of temperature-sensitive resistor commonly employed in electronics.
