First understand the function of the fuse: if the circuit fuse is placed correctly, then the fuse will rise to a certain height and after a certain period of time, the fuse will cut off the current, thereby protecting the operation of the circuit, and the

Mini fuses are mainly used in digital cameras, notebook computers, mobile phones and other electronic products. From traditional glass tube fuses to miniature fuses, because of the difference in product technology, their selection points are also slightly

The fuse current of the chip fuse is 1.5-2.0 times of the rated current. When the electrical equipment is in normal use, its fuse will not blow. When the current in the circuit exceeds 5 times of its rated current, it will Automatic fusing plays a protect

If the chip fuse has high requirements, the film process is usually used, and the very low internal resistance value is more suitable for overcurrent protection, such as surge. Computer peripherals, mobile phones and other communication equipment, digital

How to choose the elements involved in chip fuse and chip fuse selection? Chip fuse selection involves the following elements: 1. Normal working current. 2. The applied voltage applied to the chip fuse. 3. Abnormal current required to disconne

The plug-in varistor is a metal oxide semiconductor nonlinear resistance element with zinc oxide as the main component; the resistance is more sensitive to the voltage, and when the voltage reaches a certain value, the resistance is quickly turned on. Bec

How to use plug-in varistor correctly? According to different usage scenarios, the purpose of applying a varistor is that the voltage / current stress acting on the varistor is not the same, so the requirements for the varistor are also different. Pay att

Application scale of different types of resettable fuses 1. The 6V series of self-recovery fuses are suitable for circuits with low operating voltage and relatively low operating current, such as computers, computer peripherals, and toy occupations

SMD fuse material use classification: 1. 5154 aluminum plates are used in welded structures, storage tanks, pressure vessels, ship structures and offshore facilities, and transportation tanks. 2. The 5182 aluminum plate is used in thin plates for pr

Application of varistor: 1. Avoid lightning strikes When encountering thunderstorm weather, we know that the instantaneous voltage of lightning strikes can reach 100 ～ 10000V, which causes great harm. Therefore, it is necessary to adopt methods for

There are many small partners who still do not know the difference between the plug-in varistor and the patch. This article is a brief description for us, hoping that we can help in this regard. Plug-in varistor refers to a voltage-limiting compone

There are many series of fuses in the electronic component market, among which are chip fuses. This series of fuses are used more in the factory, and less used by individual users. According to industry experts, SMD fuses are a new variety with
