PTC Thermistors are temperature sensors that belong to the family of thermistors. These temperature-dependent components are made of ceramic materials with a high electrical resistance, making them sensitive to temperature changes. B59100C180A70 is such a PTC thermistor from EPCOS, whose application fields and working principle are discussed in this article.

B59100C180A70 PTC thermistors are mainly used for the detection and protection of temperature-related faults. Its wide resistance variation range of 0 - 250 Ω, makes it suitable for a variety of applications, from automotive controller protection and thermal overload protection, to SMPS and battery protection. Furthermore, B59100C180A70 thermistors have an excellent temperature dependence of -6.4mV/K to -9mV/K, making them very useful in providing the user with an accurate indication of the temperature.

The working principle of B59100C180A70 PTC thermistors is based on the electrical resistance variation, which changes dependent on the change in temperature. When the temperature increases, the electrical resistance of the thermistor also increases, and vice versa. This feature makes it a perfect device for temperature sensing and monitoring. The temperature coefficient of the thermistor also varies with the amount of heat applied - the higher the temperature, the higher the coefficient of resistance. As such, these thermistors are suitable for applications that require an accurate, repeatable, and consistent measurement of temperature, over a wide range of temperatures.

Other advantages include longer life expectancy than that of other temperature sensors, and protection against overcurrent and overvoltage. B59100C180A70 PTC thermistors also come with a wide operating temperature range of -55℃ to 175℃, making them suitable for use in a variety of industrial, automotive, and commercial applications. They are also immune to shock and vibration, and their construction means that they are resistant to moisture and other environmental conditions.

To sum up, B59100C180A70 PTC thermistors are temperature sensors that offer a wide range of uses, thanks to their wide resistance variation range and excellent temperature dependence. They are widely used in automotive and commercial applications, providing the user with reliable and consistent temperature monitoring and protection.
