PTC thermistors are temperature sensors often used in measuring high temperatures or very small changes in temperature. The B59880C0120A570 is an NTC (Negative Temperature Coefficient) thermistor that is particularly useful for high temperature applications, such as engine management systems, solar thermal applications and electronic air conditioning systems.

A PTC thermistor is a type of thermistor which has a positive temperature coefficient, meaning that its resistance increases with increasing temperature. This makes them useful for applications where the current must be limited when a device or system overheats. PTC thermistors have a characteristic "slow-time response" which means that they take longer to respond to temperature changes compared to other types of temperature sensors.

The B59880C0120A570 is a radial leaded PTC thermistor and has an operating temperature range between -40°C and +155°C, and a resistance tolerance of ±0.75%. It is a high precision device, with a temperature coefficient of resistance (TCR) of more than 40%. This indicates that the resistance increases significantly with temperature, making it an ideal choice for safety applications.

The B59880C0120A570 is typically used in motor control and protection systems, in vehicle engine management systems as well as in military applications. In engine management systems, the thermistor acts as an over-temperature protection device, limiting the current in the system if it exceeds a certain temperature. In military applications, the device is used as a temperature switch in various weapons systems.

The thermistor works by means of the principle of electricity and heat. When a current is passed through the thermistor element, the electrical energy is dissipated as heat and the resistance of the thermistor increases. This increase in resistance is proportional to the temperature, which allows for the measurement of the temperature. The thermistor also provides protection to electrical circuits by limiting or releasing current in the event of an over-temperature condition.

PTC thermistors are very reliable devices and are the preferred choice for applications requiring high temperature protection and precise temperature measurement. The B59880C0120A570 is a high precision device that can be used in a variety of temperature sensing and protection applications.
