PTC resettable fuses, also known as polymeric or polymer PTCs, are semiconductor protection components mainly used to protect electronic circuits against overcurrent and overvoltage. The RHEF1500-2 is a typical resettable fuse and is designed for over-current protection in computer, consumer, industrial, and medical applications. This article will discuss the application field and working principle of RHEF1500-2 resettable fuse.

The RHEF1500-2 resettable fuse is designed for over-current protection in a wide range of applications, including consumer electronic products such as mobile phones, tablets, digital cameras, cam players, portable media players, and computer peripherals; automotive electronics; medical electronics; and industrial electronics such as LED lighting, electric motors, and sensors. The device can also be used in power circuits and battery charging/discharging controls.

The working principle of the RHEF1500-2 resettable fuse is based on a positive temperature coefficient (PTC) thermistor, which is a self-resetting solid-state device. The thermistor has a predictable resistance-temperature relationship, meaning that when the current through the device increases, its temperature rises, which in turn causes an increase in the resistance of the device. When the resistance increases, the current through the device is reduced, which causes the temperature to decrease and the device to reset. This resetting process can occur quickly and the device can handle large over-currents while still working.

The RHEF1500-2 resettable fuse features a slim, low profile design that is ideal for use in space and weight constrained applications. The device has a high current handling capacity, robust surge capability, and a fast response time. In addition, the device has an operating temperature range of -40°C to +105°C and is RoHS compliant.

In conclusion, the RHEF1500-2 resettable fuse is widely used in consumer, automotive, industrial, and medical applications thanks to its slim, low profile design and its ability to handle large over-currents while still working. The device works on the principle of a PTC thermistor, which has a predictable resistance-temperature relationship and is able to reset quickly. The device also features a wide operating temperature range and is RoHS compliant.
