The item is one micro NTC Thermistor temperature-sensitive resistors. Quick response and good stability Micro NTC thermistor consist of NTC chip, epoxy resin and lead wire. Wire material changeable according to requirement. An NTC thermistor, also known as a Negative Temperature Coefficient thermistor, is a type of thermistor that exhibits a decrease in electrical resistance as the temperature increases. Thermistors, in general, are temperature-sensitive resistors that are commonly used for temperature measurement and control applications.

NTC thermistors are typically made from semiconducting materials, such as metal oxides like manganese, nickel, or cobalt, which have a negative temperature coefficient of resistance. This means that as the temperature rises, the number of charge carriers in the thermistor increases, leading to a decrease in resistance.
The resistance-temperature relationship of an NTC thermistor follows a specific curve, which can be described by a mathematical equation or provide in a datasheet. By measuring the resistance of an NTC thermistor, the corresponding temperature can be determined using calibration curves or lookup tables specific to be particular thermistor model.
NTC thermistors are widely used in various applications, including temperature sensing, temperature compensation, and temperature control. They can be found in household appliances, automotive systems, medical devices, HVAC systems, industrial equipment, and many other electronic systems that require accurate temperature monitoring or regulation.
