PTC resettable fuses provide power system with some degree of protection from overcurrent. This circuit protection technology is composed of polymeric PTC (positive temperature coefficient) material, which is actually a semiconductor. When subjected to overcurrent, its resistance increases sharply to limit current flow and protect downstream circuitry.

RHEF750-2 resettable fuses are widely used in communication fields, especially the data transferring and related applications. It is based on PTC conductive polymer sensing elements and exposed-electrode organic film technology. The organic film has an excellent temperature resistant performance, so it offers perfect protection for USB ports, chargers and other communication devices.

RHEF750-2 resettable fuses provide fast and accurate response when electric current is over the nominal rated value. The working principle of the fuse is quite simple, and it goes like this: when operating on the correct value, the PTC element is in low resistance state, when the current value is more than the specified rated current, the PTC element shows high resistance, thus cutting off the power supply. The returning action of the fuse is irreversible and non-destructive, which means the protective current can be reset multiple times without re-calibration or replacement.

The high voltage resistance of the RHEF750-2 resettable fuse makes the device suitable for many electronics applications. Apart from current limiting, the fuse can also provide overvoltage protection by disconnecting the load from the main power line. However, the overvoltage protection feature of the fuse has certain limits which depend on the product\'s design. The fuse can only protect the load with the current value rated within specific ranges.

The RHEF750-2 resettable fuse is suitable for circuits where a large number of components or wires may carry charge, like in lighting applications or power supplies. The flexible design of the fuse allows it to respond to changes in current, voltage, and temperature and provides high current holding capacity but with a small footprint. The fuse is also highly efficient at providing overcurrent protection for circuits in which sharp intermittent current spikes or large current draw could damage the circuit.

As mentioned before, the RHEF750-2 resettable fuse is mainly used in communication fields, enabling the current control in devices such as modems, routers, and other consumer electronics. The device is also well-suited for the automotive applications, as the fast response of the fuse saves the car\'s electronic components from being damaged by current surges or short circuits.

In conclusion, the RHEF750-2 resettable fuse is an ideal choice for the current limitation and overvoltage protection applications. The device is designed for easy installation and use and its response time is fast enough to protect downstream circuitry from overcurrent accidents. The flexible design of the fuse also makes it suitable for a wide range of applications, including automotive, communications, and consumer electronics.
