Disposable fuses can be divided into fast fuse and slow fuse. The models of disposable slow fuse available in Jidian Tong brand include: slow break JFC0603, slow break JFC1206, and slow break JFC2410.
A one-time slow blown fuse, also known as a delay fuse, has a delay characteristic characterized by its ability to remain intact during non fault pulse currents in the circuit and provide protection against prolonged overload. Some circuits have a current that is several times greater than the normal working current at the moment of switching. Although this current peak is high, it appears for a short time. We call it pulse current, also known as impulse current or surge current. Ordinary fuses cannot withstand this current, and if a regular fuse is used in such a circuit, it may not be able to start normally. If a larger specification fuse is used, it will not be protected when the circuit is overloaded. The melt of the delay fuse is specially processed and has the function of absorbing energy. Adjusting the amount of energy absorption can enable it to withstand both impact current and provide protection against overload.
