company news about What is the difference between disposable fuse and a recoverable fuse?

        The recoverable fuse is essentially a positive temperature coefficient thermistor. It protects the circuit through the positive correlation of the resistance value of the PTC material to the temperature and the sudden change at the Curie temperature point. This principle is completely the same as that of the Disposable fuse. different. The Disposable fuse is a current protector made by using the principle of breaking the circuit by melting the melt with the heat generated by itself after the current exceeds the specified value for a period of time.

        These two types of products have the following similarities:
1. Both of them can be used for overcurrent protection of circuits. Many fields and occasions are similar. In some occasions, both products can be used and can be replaced with each other. For example, the requirements for overcurrent protection are not too high. These two types of products can lead the way in battery protection applications;
2. In the application of the protection of some important devices such as IC, or the input/output of the power supply, only disposable fuses may be competent for their protection functions. These parts also have high impedance requirements; and some must be avoided due to overheating. In the event of burning out the product, or the overcurrent protection of the interface that often requires hot-swapping operations, it is the best place for PTC;

        However, in most cases, there are still many differences between these two types of products, and it is even impossible to replace each other at all. Their main differences can be reflected in the following table:

        Due to the existence of similarities and differences, these two types of products can coexist in the market for a long time.
