　　　　It is demonstrated that the circuit remains intact when there is a non fault pulse current and can provide protection against long-term overload.　　Delay fuses are used in some circuits where the current at the moment of switching is several times greater than the normal working current. Although this current peak is high, it appears for a short period of time, and we call it pulse current. Ordinary fuses cannot withstand this current, and delay fuses are needed in such circuits. If larger fuses are used, they 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. The standards for delay fuses have regulations on delay characteristics. If the specified characteristics cannot meet your requirements, you can contact the delay fuse manufacturer for a solution.

　　　　Patch fuses can be divided into disposable patch fuses and patch self recovery fuses. After being protected by a disposable fuse, it needs to be replaced. After being protected by a self recovery fuse, it can be restored and reused after power failure.　　But what should we pay attention to when choosing patch fuses? The editor suggests selecting fuses based on the following aspects: normal current, fusing current, open circuit voltage, short circuit current, impulse current, and ambient temperature.　　Short circuit current: We refer to the maximum current that flows when a circuit is short circuited as the short circuit current. For various fuses, the rated breaking capacity is specified, and we must be careful not to exceed the rated breaking capacity when selecting fuses. If a fuse with a small breaking capacity is selected, it may cause the fuse to rupture or cause a fire.　　Impulse current: Observe the waveform of the impulse current (pulse current waveform) and calculate its ener

Principle and characteristics of self recovering fuses

　　Principle and characteristics of self recovering fuses　　With the rapid development of technology, our daily lives are increasingly dependent on various electronic devices. However, the normal operation of these devices relies on a stable and reliable power protection system. As an innovative power protection solution, self recovering fuses are gradually becoming an indispensable part of modern electronic devices.　　Self recovery fuse is a type of fuse with overload protection function, whose main principle is to quickly cut off the current when it exceeds the rated value to prevent equipment from overheating or damage. After the current returns to normal, the self recovering fuse will automatically return to its normal working state without manual intervention. Compared with traditional fuses, self-healing fuses have the following characteristics:　　a. Self recovery function: Once the current returns to normal, the self recovery fuse will automatically return to its normal working stat

Installation Precautions for Current Fuses

　　　　The installation of current fuses is crucial for ensuring the safety and proper functioning of electrical circuits. Here are some important installation precautions to keep in mind.　　First and foremost, make sure to select the right fuse for the specific application. Consider the current rating, voltage rating, and interrupting capacity of the fuse. Choosing an incorrect fuse can lead to overheating, failure to protect the circuit, or even pose a safety hazard.　　Before installing the fuse, ensure that the power is turned off to the circuit. This will prevent any accidental electrical shocks or damage to the fuse during installation. Use appropriate tools and follow proper electrical safety procedures when working with live circuits.　　When installing the fuse, make sure it is inserted correctly into the fuse holder. Ensure a tight and secure fit to ensure proper electrical contact. Loose or improperly installed fuses can cause arcing, overheating, and potential fire hazards.　　Check

　　　　Chip fuses are crucial for electronic devices such as digital cameras, laptops, and mobile phones.. From traditional glass test tube fuses to small fuses and patch fuses, the focus of their selection is slightly different due to the differences in new technologies of the products.　　(1) Current in the normal operation of the circuit. According to the operation of the fuse, the current should not exceed 75% of the rated current of the fuse.　　(2) Single pulse, impulse current, Surge protector current, operating current and circuit instantaneous value. Please note this when integrating IC fuses. Due to the processing technology caused by small specifications, the impact resistance of built-in fuses is much lower than that of glass tube fuses with the same rated current or other oversized fuses.　　(3) The size of overload current and the minimum and longer duration of overload current. It is generally necessary to use digital oscilloscope detection and conceptual calculation to distingui
