　　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.

Application of self recovery fuse in overcurrent protection of Industrial internet of things equipment

　　　　USB ports are increasingly included in Industrial internet of things (IIoT) devices. The data speeds of USB 3.0, 3.1 and 3.2 vary from 5GB/s to 20GB/s. USB protocol can provide bandwidth and reliability required by almost all industrial applications. The USB port provides a connection between the host and IIoT devices for real-time monitoring and control, enabling users to make smarter decisions and improve productivity across multiple processes. Overcurrent and overvoltage in IIoT devices may be caused by power overload, surge, or short circuit, which can generate a large amount of heat and increase the risk of physical damage or electrical fire.　　self recovery fuses can disconnect the circuit during a fault event like disposable fuses, but they are recoverable, allowing them to achieve longer lifespan of the product. Each fuse is composed of a positive temperature coefficient material, and its internal resistance increases exponentially with increasing operating temperature. The

　　　　According to the protection form, it can be divided into overcurrent protection and overheating protection. The fuse used for overcurrent protection is commonly referred to as a fuse (also known as a current limiting fuse). The fuse used for overheat protection is generally called "Thermal cutoff". Thermal cutoff can also be divided into low melting point alloy, temperature sensing trigger and memory alloy (Thermal cutoff is used to protect heating appliances or easily heating appliances from high temperature, such as hair dryer, electric iron, rice cooker, electric stove, transformer, motor, etc.; it responds to the rise in temperature of electrical appliances and does not care about the working current of the circuit. Its working principle is different from "current limiting fuse").　　According to the scope of use, it can be divided into: power fuse, machine tool fuse, electrical instrument fuse (electronic fuse), and automotive fuse.　　According to body integration, it can be divi

　　　　The self-healing fuse PPTC is a type of overcurrent electronic protection component, which is made by adding conductive particle materials to a polymer organic polymer under high pressure, high temperature, and vulcanization reaction conditions, and processed through a special process. Self recovery fuse (PPTC: Polymer self recovery fuse) is a positive temperature coefficient polymer thermistor used for overcurrent protection and can replace current fuses. When the circuit is working normally, its resistance value is very small (voltage drop is very small). When the circuit experiences overcurrent and causes its temperature to rise, the resistance value sharply increases by several orders of magnitude, reducing the current in the circuit to below the safe value, thus protecting the subsequent circuit. After the overcurrent disappears, it automatically returns to a low resistance value. The above is the working principle of a self recovery fuse.　　Chip self recovery fuse　　Most people

What happens if a car fuse is damaged.bussmann fast acting fuse

　　　　The function of car fuses is to maintain circuits (routes) and electrical and mechanical equipment. A car fuse is a type of current fuse. When the circuit current exceeds twice the rated voltage of the fuse, it will melt within a few seconds and have the effect of circuit maintenance. Commonly used for overcurrent protection in automotive circuits.　　What happens when a car fuse is damaged? The situation is as follows:　　1. The car cannot start a fire, and the ignition coil has no power. It is necessary to check if the fuse of the ignition coil is damaged, causing the ignition coil to have no working voltage;　　2. The car mounted cigarette lighter cannot be used, and it is necessary to check whether the commercial fuse of the car mounted cigarette lighter in the fuse box is damaged;　　When the vehicle is driving, the speedometer is zero and the ABS warning light flashes, but the speedometer is normal and the fuse that matches the ABS is burned out.
