PTC thermistors, also known as Positive Temperature Coefficient thermistors, are temperature sensors or detectors with a unique property: they change their resistance with temperature in a predictable, linear way. PTC thermistors are commonly used in applications where the temperature can be measured accurately over a wide range of temperatures, such as in automotive and industrial environments. B59910C0120A070 is a PTC thermistor designed specifically for high temperature, high performance applications. This article examines the application field and working principle of B59910C0120A070.

Application Field and Working Principle

The B59910C0120A070 PTC thermistor is designed for wide temperature range applications and can operate between −55 to +270°C. This thermistor is mainly used for temperature measurements, with an accuracy of ±1°C and a temperature coefficient of 1.75%/°C. This makes the B59910C0120A070 ideal for applications where accuracy is a priority, such as in automotive and industrial environments. This thermistor can also be used for over-temperature protection, controlling hot-spots, measuring surface temperature, and for temperature control in HVAC systems.

The working principle of the B59910C0120A070 is quite simple. When using a PTC thermistor, an electrical current encircles the device and the thermo-conductive property of the surrounding material produces a temperature gradient across the thermistor. This temperature gradient causes the temperature sensitive material to increase its resistance with an increase in temperature, and to decrease its resistance with a decrease in temperature. This phenomenon is responsible for the linear resistance temperature characteristic of the B59910C0120A070, and allows the device to be used as an accurate temperature sensor.

Conclusion

The B59910C0120A070 PTC thermistor is a high-performance thermistor designed specifically for wide temperature range applications, and can accurately measure temperature over a range of −55 to +270°C. Its temperature coefficient is 1.75%/°C, and it can be used for over-temperature protection, controlling hot-spots, measuring surface temperature, and for temperature control in HVAC systems. This thermistor is ideal for applications where accuracy is a priority, such as in automotive and industrial environments.
