Reasons for the increasing importance of circuit protection components.china hs code for fuse

　　　　In daily life, electronic products are everywhere, and circuit protection has become increasingly important. In order to make circuits safer, engineers are constantly studying the safety and reliability of products. The main reasons for this are as follows:　　(1) With the demand for the development of electronic products, the functionality (integration) of ICs is also becoming stronger, and their "value" is naturally becoming more noble, so it is necessary to strengthen protection.　　(2) In order to reduce power consumption, reduce heat generation, and extend service life, the working voltage of semiconductor components and ICs is getting lower and lower. According to statistics from the American Semiconductor Industry Association, the current working voltage is around 1.5V, which will decrease to a lower level in the following years. Therefore, its ability to withstand overcurrent/overvoltage needs to adapt to new protection requirements.　　(3) There are more and more mobile electron

Detailed Explanation of the Development History and Trends of Surface Mount Fuses.fast blow or slow blow fuse for microwave

　　　　In the long history of the development of fuses, the development has shifted from cylindrical, plug-in, axial or radial pin shapes to miniaturization and SMD. In more and more portable handheld electronic products, the application of SMD fuses has also begun to show an increasing trend.　　In just twenty years, the development of surface mount fuses has accounted for 30% of the overall small fuse application market, and is continuously expanding, gradually replacing other traditional forms of fuses, indicating its strong vitality.　　In 2005, the development of SMT fuses was increasing day by day, accounting for one-third of the total market share not only in terms of quantity but also amount. This has greatly promoted the development of the electronic industry and led to a continuous growth trend in the small fuse market. Surface mount fuses are the most valuable variety among small fuses, and their prices are also facing fierce competition, showing a decreasing trend year by year. Be

　　　　1. Determine the following parameters of the circuit:　　A Large working environment temperature b Standard working current c Maximum working voltage (Umax) d Maximum fault current (Imax)　　2. Select self restoring fuse components that can adapt to the ambient temperature and standard operating current of the circuit　　Use a temperature reduction {ambient temperature (℃) working current (A)} table and select the temperature that best matches the ambient temperature of the circuit. Browse this column to view values that are equal to or greater than the standard operating current of the circuit.　　3. Compare the high electrical rating of the selected component with the high operating voltage and fault current of the circuit　　Use the electrical characteristic table to verify whether the components you selected in step 2 will use the high operating voltage and fault current of the circuit. Check the high operating voltage and high fault current of the device. Ensure that Umax and Imax are g

The Protection Application of Self Recovery Fuses in Electric Toys.fast acting fuse bussmann

　　　　With the development of technology and social progress, people are paying more and more attention to the intellectual development of infants and young children. Various educational toys are springing up one after another, including electric and non electric ones, with thousands of types and varying quality requirements.　　When people purchase toys, they often pay more attention to their playable functions and neglect their safety. Many toy quality issues are only taken seriously when accidents occur, but it is too late and have already caused harm to people, some of which may last for a lifetime.　　In foreign countries and particularly developed countries, the safety of electronic toys is the most important. Regardless of certification, testing, research and development design, customer requirements, etc., the first consideration is safety, followed by the functions of toys, especially electric toys. Therefore, the safety protection of toys is the primary issue. In clause 3.6.2 of th

Selection of fuse type.motorcycle fuse box waterproof

　　　　Select the type of fuse based on the electrical load characteristics in the circuit (slow melting or fast melting fuse). Fuses can be divided into slow fuse and fast fuse according to their different fusing characteristics. Fast melting fuses are commonly used in resistive circuits to protect components that are particularly sensitive to current fluctuations; Slow melting fuses are commonly used to quickly disconnect circuits when there is a fault with a large surge current when the circuit status changes.　　Finally, according to the sensitivity/capacitance circuit (such as the fan motor circuit), it can withstand the impact of surge pulses when switching on and off the machine, and the appropriate fuse type of structure is selected for the actual assembly position where the fuse wire appears. Priority should be given to fuses that occupy little space after installation.
