The NTC thermistor 50k is a type of temperature sensor widely used in various industries. It offers accurate temperature measurements, making it an essential component in many electronic devices and systems.

Thermistor Overview

A thermistor is a type of resistor whose resistance changes with temperature. The NTC (Negative Temperature Coefficient) thermistor, as the name suggests, exhibits a decrease in resistance as the temperature rises. This characteristic makes it ideal for temperature sensing applications.

Working Principle

The working principle of an NTC thermistor 50k is based on the change in resistance with temperature. As the temperature increases, the resistance decreases. This property allows precise temperature measurements by monitoring the resistance value of the thermistor.


The NTC thermistor 50k finds applications in various fields, including:

  • Temperature monitoring in HVAC systems
  • Overheating protection in power supplies
  • Thermal compensation in precision circuitry
  • Process control in industrial environments
