Working Principle

The B59771C0120A070 PTC thermistor is a temperature-sensing device based on a solid-state principle. It works by sensing the temperature of the environment and altering its electrical characteristics in response to the temperature changes. The device is made up of a ceramic material containing a metal oxide whose electrical resistance increases when the temperature increases and decreases when the temperature decreases. The resistance value of the PTC thermistor is calibrated and can be used to measure temperatures between - 40°C and +90°C with an accuracy of ±2 over the temperature range.

The device is available in two versions – standard version and low impedance version. The standard version allows for a longer lead length, while the low impedance version lowers the voltage drop across the lead to reduce the heating effect of the lead. The B59771C0120A070 PTC thermistor can be used as a temperature sensor in applications such as motor control and temperature sensing. The device has a fast response time and is designed for high accuracy. It can also be used for temperature-dependent output control, providing a reliable and accurate temperature measurement solution for a wide range of applications.
