youtube fuseschool.Does the fuse have a resistance value?

　　　　Fuses have resistance values, but in fact, even wires have resistance. However, the resistance of the wires is very small (the nature of the conductor), which is usually ignored in general circuit calculations. However, the resistance of a fuse is significantly higher than that of an equally long wire, so that it can protect the circuit.　　The fuse is marked with "5A 250V", indicating that the maximum current allowed for Shenzhen fuses is 5A, which is called the rated current; The maximum voltage allowed to pass through is 250V, which is called the rated voltage. If the current or voltage exceeds the rated value, the fuse will blow, causing the circuit to open, thus protecting the consumer (without a fuse, the consumer may be burned out).　　The principle of fuse blowing is Joule's law. Joule's law: The heat generated by an electric current passing through a conductor is proportional to the square of the current, to the resistance of the conductor, and to the time it is energized. Jou

motorcycle blown fuse symptoms.The Price Trend and Future of Fuses

　　　　We know that in recent years, especially since 2016, domestic factories have increased their machinery and equipment on a large scale, especially the increase in square and SMD fuse automata, which has led to a continuous decline in these products in China. Especially, the price of square fuses has become transparent to the point where customers do not want to negotiate. There are actually several reasons for this situation:　　1: It is the continuous decline of the Chinese yuan, the constant hovering of the US dollar exchange rate, and the depreciation of the Chinese yuan　　2: There are too many homogeneous products, and in order to win more orders, we can only continuously compress profit margins, which is a common problem in the domestic manufacturing industry　　3: After the tax increase in the United States, many orders have been sharply reduced, especially the significant impact of large customer revenue, further forcing fuse factories to compress profit margins and dilute operati

Selection of 0.5A chip fuse.car fuses near me

　　　　The series models with a rated current of 0.5A in SMD fuses include ASMD0603-050, ASMD0805-050, ASMD1206-050, ASMD1210-050, ASMD1812-050, and ASMD2920-050. When selecting 0.5A patch recoverable insurance, in addition to considering the current, we also need to consider the voltage in the circuit. The maximum voltages for the above models in order are: 6V, 6V, 13.2V, 15V, and 60V. In addition to considering the voltage and current parameters, we also need to consider the requirements of the board for the fuse packaging size. The size of the 0603 is 1.6mm * 0.8mm, the size of the 0805 is 2.0mm * 1.2mm, the size of the 1206 is 3.2mm * 1.6mm, the size of the 1210 is 3.2mm * 2.5mm, and the size of the 2920 is 7.5mm * 5.5mm.　　0.5A circuit patch fuse selection, with a protective current of 1A, can restore the operating temperature range of the fuse to -40 ℃~+85 ℃ for patches above 0.5A. Usually, we use reflow soldering, which is mainly used for surface mounted boards, that is, for chip fu

The Importance of Fuses in Safe Sockets.battery terminal fuse replacement

　　　　A safety socket generally refers to a socket with a fuse and a power on indicator light. Usually, it has the characteristics of preventing leakage, overcurrent, high temperature, and lightning strikes, so safe sockets are also very popular in daily life. Today, I will tell you the importance of fuses in safe sockets　　In recent years, with the rapid development of science and technology and the widespread application of safety sockets, safety issues have also risen to a new level. In safety sockets, it is worth noting that when a fuse is blown, do not connect a wire to save time, as this will not function as a safety measure. It's best to go to a hardware store to purchase fuses or have a professional electrician repair them~!　　At the same time, the socket hole of the safety socket is covered by a layer of baffle, and you must use a pin to pass through the socket, which cannot be touched by hand.

How to judge the quality of ceramic tube fuses?

　　　　1. Introduce the function and classification of ceramic tube fuses, and emphasize the importance of judging their quality.　　Ceramic tube fuse is a common electronic component mainly used to protect circuits from damage caused by overload or short circuit faults. According to different rated currents and voltages, ceramic tube fuses can be divided into various models of different specifications. It is very important to judge the quality of ceramic tube fuses in use, which can ensure the normal operation and safe use of the circuit.　　2. Introduce how to judge the quality of ceramic tube fuses through visual inspection.　　Visual inspection is one of the most basic methods to determine the quality of ceramic tube fuses. Firstly, the fuse housing should be checked for any obvious damage or deformation. Secondly, it is necessary to check whether the contact between the two ends of the fuse is tight and whether there is oxidation or corrosion. Finally, the surface of the fuse should be che
