PTC resettable fuses are made up of a special temperature-sensitive polymer, combined with metal elements, and sometimes with additional protection layers. Designed to act as a circuit breaker, as soon as they detect an overcurrent situation they will activate their switching mechanism, interrupting the electrical flow, thus protecting the circuitry from fire or damage danger. The LR4-700XHF is one such fuse, providing reliable overcurrent protection which makes it particularly suitable for embedded and automotive applications.

The LR4-700XHF exceeds current industry standards for robustness and is UL recognized, meaning it can be used confidently in many electrical circuits. The integrated PTC element of this type of fuse allows it to detect an overcurrent in the circuit and automatically open it to protect the other components from harm in the event of an overload. As soon as the current is brought back down to safe levels, the element automatically resets, and the affected circuit returns to full operation.

The LR4-700XHF performs best in power supplies and protecting primary wires and its primary use is in low-voltage applications, such as power distribution, networking, consumer and home – appliances, computer peripherals, DC and AC electrical systems. The particularly low voltage rating of this type of fuse (just 6.3V) makes it suitable for devices that use the USB standard, such as USB chargers, but also for other low-voltage devices such as smart phone chargers, or even remote sensing and control applications.

The LR4-700XHF offers a current rating of 700mA, with a maximum voltage rating of 6.3V. It is also good for low surge applications due to its fast acting current limiting function. It also features a positive temperature coefficient (PTC) for superior overcurrent protection. The fuse is very accurate, having a tolerance range of ±(5%) compared to other resettable fuses of similar ratings.

The key working principle of the LR4-700XHF is based on a positive temperature coefficient (PTC) element which is the element that is responsible for detecting overcurrent in the circuit. This PTC element will heat up when a current is higher than normal and will act as a switch, interrupting the current and thus preventing the other components in the circuit from suffering any damage. As soon as the current returns to safe levels, the PTC element will cool off and it\'s own circuit will be restored, allowing current to flow again.

The LR4-700XHF is a reliable, cost effective and durable solution for protecting circuits from overloads and helping to maximize the life of electronic equipment. It is versatile and compact, making it ideal for use in various applications, especially those which require sensitive overcurrent protection, such as those in consumer electronics, telecommunication systems, automotive electronics, and renewable energy systems.
