PTC Resettable Fuses

A PTC resettable fuse, also known as a polyfuse, is a type of self-resetting fuse used primarily in electronic circuits to protect against overcurrent or short circuits. Unlike traditional fuses, which require replacement when they blow, PTC resettable fuses are designed to open automatically when the current exceeds a certain limit, and then reset themselves when the current goes back below the limit. This makes them ideal for applications where it is not feasible to do frequent fuse replacement.

72R075XU Application Field and Working Principle

The 72R075XU is a PTC (positive temperature coefficient) resettable fuse from Littelfuse. It is designed for use in consumer and automotive applications, and is suitable for protecting against overcurrent or short circuit conditions. It features a temperature range of -40°C to 125°C, a self-resetting time of 2 seconds or less, and a maximum current rating of 7.5A.The 72R075XU is a positive temperature coefficient, or PTC, fuse. This means that its resistance increases as its temperature increases. The fuse contains a special thermally sensitive material that is designed to open when its temperature rises due to an overload or short circuit. When this happens, the current is diverted from the circuit and the fuse will trip. Once the overload or short circuit is removed, the fuse will cool down and its resistance will decrease, allowing the current to flow again. The 72R075XU has a fast reset time of 2 seconds or less, so it can quickly reset itself and resume normal operation.The 72R075XU can be used in a variety of automotive and consumer applications for protection against current overloads or short circuits. It is commonly used in automobile and industrial equipment systems, as well as motorized toys. Its small size makes it ideal for these applications as it can easily be integrated into any design.In summary, the 72R075XU is a PTC resettable fuse from Littelfuse designed for use in consumer and automotive applications. It is designed to protect against overcurrent and short circuit conditions, and features a temperature range of -40°C to 125°C and a self-resetting time of 2 seconds or less. It is commonly used in automobile and industrial equipment systems, as well as motorized toys, and its small size makes it easy to integrate into any design.
