Many users have told me about buying printers, but when asked which one they want to buy, they can't tell. Before purchasing a printer

　　　　A general fuse consists of three parts: one is the melt part, which is the core of the fuse and plays a role in cutting off the current when blown. Fuses of the same type and specification should have the same material, geometric size, resistance value as small and consistent as possible, and the most important thing is to have consistent fusing characteristics. Household fuses are commonly made of lead antimony alloy lead; The second is the electrode part, which usually has two important components that connect the melt to the circuit. It must have good conductivity and should not generate obvious installation contact resistance; The third part is the support part. The melt of the fuse is generally thin and soft. The function of the support is to fix the melt and make the three parts a rigid whole for easy installation and use. It must have good mechanical strength, insulation, heat resistance, and flame retardancy, and should not produce phenomena such as breakage, deformation, c

Safe use of electricity, safety of fuses.slow blow fuses near me

　　　　On June 30th, an employee of a power supply company in Gansu received a call from customer Yang, saying, "My house has a power outage, and the TV still has a burning smell. Can you please come over and take a look　　After the employees of the power supply company had a preliminary understanding of the power outage at Yang's house, the director of the office immediately arranged for the duty officer Wang to rush to the customer's house. Pushing open the door of Yangmoujia's room, a burning smell filled the room. Therefore, Wang immediately began to carefully inspect the wiring direction of Yang's house. With years of work experience, Wang went straight to the customer's knife switch and found that the fuse was intact without any signs of burning out. Upon closer inspection, he found that the fuse was actually replaced with copper wire.　　After the employees of the power supply company had a preliminary understanding of the power outage at Yang's house, the director of the office immed

What is the reason why the fuse keeps burning out?

　　　　1. Exceeding rated power: Fuses have a certain rated power, and when the power of electrical equipment exceeds the rated power of the fuse, it will burn out. The function of a fuse is to protect the circuit and prevent overload.　　2. When the current resistance value of the fuse exceeds the rated current value and burns out: When there is a short circuit or poor contact in the circuit, excessive current will be generated, causing the fuse to burn out. At this point, it is necessary to check whether the circuit is normal and whether the current withstand value of the fuse exceeds the rated current value.　　3. Use environment of fuses: The service life of fuses is affected by the ambient temperature. If the ambient temperature is too high, the service life of fuses will be shortened and they are prone to burning out.　　4. Material of fuses: Fuses made of different materials have different high temperature resistance performance. If the material of the fuse is not suitable, it is also ea

Surface Mount Fuses

　　　　Surface mount fuse is a widely used protective component in electronic circuits.　　Structurally speaking, patch fuses are compact in size and typically flat in shape. They are designed to be suitable for surface mount technology (SMT) and can be easily installed on printed circuit boards (PCBs). This compact structure gives it a unique advantage in the trend of miniaturization in modern electronic devices, effectively saving space on circuit boards.　　Its working principle is based on the thermal effect of electric current. When the current in the circuit exceeds the rated current of the patch fuse, the resistance wire inside the fuse will heat up, and as the heat accumulates, the temperature of the resistance wire will rapidly rise. When the temperature reaches the melting temperature of the fuse, the resistance wire will melt, thereby cutting off the circuit and protecting other components in the circuit.　　In terms of application fields, patch fuses are very common in various consu
