PTC thermistors refer to a type of temperature sensor, known as a Positive Temperature Coefficient Thermistor (PTC). PTC thermistors are semiconductor materials, typically made of polycrystalline ceramic, which exhibit a remarkable property as they are heated, their resistance increases exponentially. This temperature sensitive response makes them ideal as a temperature sensor, as the resistance increases as the temperature rises, making it easy to measure the temperature using a simple voltage or current measurement.

The B59300M1080A70 is a PTC thermistor, and is widely used in a variety of applications. It is often used in temperature sensing applications, where it provides a cost-effective solution to temperature sensing. The PTC thermistor can be used as a temperature threshold device to shut off power when a particular temperature is exceeded, for instance in heating systems or motors. The thermistor can also be used in temperature measurement applications, where it allows for accurate temperature readings without the need for a complex thermocouple system.

The B59300M1080A70 PTC thermistor is also suitable for over-temperature protection applications, due to its robust design. In this application, the thermistor is wired in series with the power supply, such that as the temperature rises, the resistance of the thermistor increases, blocking the current and thus protecting the device from overheating. This type of over-temperature protection can be applied to motors, transformers, and other electrical equipment.

The B59300M1080A70 PTC thermistor also has applications in medical instruments and electronic circuits. In the medical field, PTC thermistors are used for temperature sensing in MRI and CAT scans. In electronic circuits, PTC thermistors are used to regulate power, as they act to limit the current flow and protect components from overheating, thus providing circuit protection. They are also used in over-voltage and over-current protection for power supplies in electronic devices.

The working principle of a PTC thermistor is quite simple. As the temperature around the thermistor increases, the resistance of the thermistor also increases, as the material it is made from exhibits a positive temperature coefficient. The increase in resistance can be used to accurately measure the temperature of the surrounding area, as the resistance will rise in a predictable manner according to temperature. This makes the B59300M1080A70 PTC thermistor ideal for temperature sensing, over-temperature protection, and other temperature-dependent applications.
