PTC Resettable Fuses are composed of a semiconductor material and a conductor. When the temperature rises, electricity passes through the semiconductor and a reaction happens that warms up the element. When the temperature reaches a certain point, the resistance increases quickly to stop current flowing through the element. After the temperature decreases, the resistance falls back to an initial state and current continues.

The PTS18126V260 is a leading PTC resettable fuse from Littelfuse. It provides reliable overcurrent protection that consistently trips before an opto-electrical damage occurs. This resettable fuse is suitable for both AC and DC circuits and provides up to 1.5A of current protection. It is provided in a radial leaded package and requires a minimum temperature of 70℃ for tripping.

The working principle of the PTS18126V260 PTC resettable fuse is fairly simple. It uses a positive temperature coefficient (PTC) technology. As current passes through the fuse, it generates heat, causing the resistance of the device to increase. When the current reaches a critical point, the resistance will quickly rise to near infinite, shutting off the circuit. Once the temperature decreases, the resistance will fall back to its original state and the circuit will be re-energized.

The PTS18126V260 is most commonly used in a variety of applications, such as appliances, power tools, lighting, automotive, medical, industrial, consumer electronics, and many other high-power electronic devices. In these applications, the PTC resettable fuse provides reliable overcurrent protection that stops current before any potential damage to the device can occur. It is also preferable for these applications since it only requires minimal temperature for tripping while providing the high current protection necessary for electronic devices.

To sum up, the PTS18126V260 PTC resettable fuse from Littelfuse is designed to provide reliable overcurrent protection. It has a positive temperature coefficient (PTC) technology, enabling it to trip when the temperature reaches a certain point. This makes it suitable for a variety of applications, such as appliances, power tools, lighting, automotive, medical, industrial, and consumer electronics. It requires minimal temperature to trip and provide the necessary high current protection for electronic devices.
