PTC Resettable Fuses are a type of circuit protective device that can offer a combination of both overcurrent protection and limitation. This type of fuse is especially useful in applications where the device needs to be reset if the current exceeds its rating. One such device is B59980C0120A070.

The B59980C0120A070 is a polymeric positive temperature coefficient (PPTC) resettable fuse, equipped with a twist-to-reset feature for protection against overtemperature and overcurrent. It is designed to protect circuits from short circuits, overloads, and overtemperature conditions. This device combines both overcurrent protection and thermal protection in one package. This device is designed for low-voltage, low-power applications such as automotive, industrial, and consumer electronics.

The B59980C0120A070 has a wide range of current ratings available from 0.6A to 25A. These devices feature an adjustable trip level current, from 1.6A to 10A, and a thermal operating temperature range from -40 degrees Celsius to 125 degrees Celsius. The devices also have a low resistance of 0.15 Ohms and a high surge current of last 60A. These features make the devices well-suited for use in low current, high temperature environments.

The working principle of the B59980C0120A070 is based on the property of a PTC thermistors. PTC thermistors are thermally sensitive semiconductor devices whose resistance increases exponentially with an increase in temperature. The PTC thermistors in the B59980C0120A070 are designed to detect an overcurrent and then heat up, causing an increase in their resistance. This increase in resistance causes the device to trip and break the circuit, which can then be manually reset when the current and temperature returns to normal.

The B59980C0120A070 is ideal for overcurrent protection and management in low current, high temperature environments. It is suitable for a wide range of applications such as automotive, industrial, and consumer electronics. This device is designed to offer reliable protection from overloads, short circuits, and overtemperature conditions, and can be easily reset when required.
