　　The material of a fuse has a decisive impact on its performance. Based on the search results, we can obtain the following information:

　　Fuses are generally made of silver copper alloy with high resistivity and low melting point. This alloy has good conductivity and melting characteristics, which can quickly melt when the current is too high, thus protecting the circuit. Early fuses were often made of lead antimony alloy, but due to safety reasons, this material has been phased out.

　　When choosing fuse materials, factors to consider include melting point, resistivity, conductivity, mechanical strength, and corrosion resistance. Different application scenarios may require different types of fuses, so the requirements for materials may also vary.

　　In summary, modern fuses are mainly made of silver copper alloy and no longer use lead antimony alloy. When selecting fuse materials, multiple factors should be considered comprehensively to ensure their reliability and safety in specific environments.

eve temperature balancing mattress protector.Principles for selecting fuses and fuses

　　　　1. Select the model of the fuse according to the circuit requirements and installation conditions. For circuits with small capacity, choose semi enclosed or unfilled enclosed; The choice for high short-circuit current is the enclosed type with fillers; Select fast fuses for semiconductor component protection.　　2. Select the rated voltage of the fuse according to the line voltage.　　3. Select the rated current of the fuse according to the load characteristics.　　4. The selection of different levels of melts requires mutual coordination, with the latter level being smaller than the previous level. The current on the main switch and each branch line is different, and the selection of fuses is also different. If a short circuit occurs in the circuit, the 15A and 25A fuses will fuse simultaneously, and the protection characteristics will lose selectivity. Therefore, only by maintaining a 2-3 level difference between the main gate and the branch can such a phenomenon not occur. If the low-

　　　　Fuses are a commonly used component in electrical circuits. Only with fuses can our circuits work safely and reliably. Do you know how fuses work?　　The core component of a fuse is a section of gold with a lower melting point　　As a wire, the fuse itself can also conduct electricity. Fuses are usually installed at the inlet of a circuit. When the circuit is connected, current flows through the fuse and the load, allowing the load to function normally.　　When the circuit is working normally, the current flowing through the fuse will not be very high, and the temperature of the fuse will not be very high.　　3. Due to the fuse being connected in series at the incoming position of the circuit, as the load in the circuit increases, the current flowing through the fuse will also increase.　　4. As the current flowing through the fuse increases, the temperature of the fuse will increase.

Design principle of patch fuse.starter motor fuse

　　　　Most SMD fuses look like standard SMD devices, using single or multi-layer ceramic substrates. Some previous designs used epoxy glass fiber substrates similar to printed circuit boards. Its structure includes: a shell, a lower cover, quartz sand, a fuse, and two terminal blocks. The shell is a ceramic box like structure without a bottom surface, and the two terminal blocks are connected together through a suspended fuse set inside the shell, which is clamped on the edge of the shell. The basic fuse in the middle is a high conductivity material, such as copper, gold or copper tin, silver palladium alloy.　　Depending on the type of substrate, the fuse can use laser fine tuned thick film deposits or chemically etched metal layers to achieve the desired performance parameters, and adhesive gold wires can also be used. Due to the determined shape and thickness, when subjected to overvoltage and the current reaches a certain level, the fuse will fuse within a certain period of time.　　To a
