PTC Resettable Fuses are simple devices that contain a resistor and a small metal strip that is designed to heat up when an electric current is sent through it. The fuse is designed to automatically reset when the current is removed, allowing it to continue to provide a reliable power connection without having to be replaced. MICROSMD400LR-2 is one example of a PTC Resettable Fuse, designed to provide 100V DC at up to 20A. It is designed to provide continuous protection without having to be reset manually.The primary application field for the MICROSMD400LR-2 is for use in consumer electronics, such as laptops, smartphones, tablets, TVs and other portable devices. The PTC Resettable Fuse is designed to detect any high current or over temperature conditions that could potentially cause permanent damage to the device, allowing it to quickly disconnect the circuit and prevent damage. Additionally, the device can provide ESD protection and can be used in a variety of applications in industrial or medical applications.The working principle behind PTC Resettable Fuses is fairly simple – when the device is placed in the circuit and a current is passed through it, the metal strip will heat up and open the circuit, allowing the current to be removed. Once the current is removed, the metal strip will cool down and reconnect the circuit, allowing the current to flow again. This ensures that the device will always be able to quickly disconnect the circuit in the event of a power surge.The MICROSMD400LR-2 is one of the most popular types of PTC Resettable Fuses due to its high output, low voltage rating, and its ability to be reliably reset without having to be replaced. Additionally, the device is designed to provide reliable protection from over current and over temperature conditions, making it a great choice for any application where reliable power connections are needed.In conclusion, the MICROSMD400LR-2 is an excellent choice for use in any application where reliable power connections are needed without sacrificing safety or performance. The PTC Resettable Fuse is designed to quickly disconnect the circuit in case of a power surge or over temperature event, ensuring that any potential damage is avoided. Additionally, the device can be reliably reset without having to be replaced, allowing it to provide continuous protection without manual intervention.
