　　The segmented capacity of the 1206 series 40A disposable fuse is as follows. When the current passing through the fuse is 40A, the fuse can maintain internal fusing for at least 4 hours. However, when the current passing through the fuse is 3.5 times the rated current, which is 140A, the fuse will fuse within 5 seconds, thereby protecting the board. The size specification of this part number is: 3.2mm * 1.6mm, with a thickness of 0.75mm

　　The 1206 series 40A disposable fuse has set industry standards in terms of performance, reliability, and quality. The solderless design provides excellent switching and temperature cycling characteristics during use, and enables our SMD fuses to have higher heat resistance and impact resistance than other subminiature fuses.

　　The main characteristics of the 1206 series 40A disposable fuse include: ① rapid fusing; ② Reflow soldering and wave soldering are compatible; ③ Ceramic and glass structures; ④ It belongs to the disposable fuse type; ⑤ Lead free and halogen-free materials. The normal operating temperature range for this part number is -55 ℃~+125 ℃.

　　The welding methods for 40A disposable fuse include wave soldering and reflow soldering. The temperature requirement for wave soldering is 260 degrees Celsius, and the time cannot exceed 10 seconds; The temperature requirement for reflow soldering is 260 ℃, and the time cannot exceed 30 seconds.

　　　　Due to the fact that the intelligent control part of this new type of LED explosion-proof light is completed through RS485 serial communication, it was found in practical applications that the 485 interface chip is easily burned out. After analysis, overvoltage protection was not done properly, so TVS tube was selected as the overvoltage protection circuit, and it was found that it is still easy to be burned out by lightning.　　When I was in a state of exhaustion, I saw an overcurrent protection scheme using a self recovery fuse TVS tube. The experiment was successful, greatly improving the reliability of the explosion-proof lamp. I didn't expect to use a self recovery fuse PPTC in series at port 485, and then connect TVS in parallel to complete the task. There is no simpler solution than this method.　　The self restoring fuse PPTC is an overcurrent protector, also known as a ten thousand fuse, also known as a self resetting overcurrent protector or a polymer self restoring fuse.

What are the precautions for car fuses?resettable 3 amp fuse

　　　　Of course, car fuses are used in cars. Some vehicle wiring connections should be used for automotive fuses. Pay attention to small things when using car fuses. Next, I have summarized some questions about automotive fuses for everyone. Let's give us an example.　　Reminder everyone, there are some issues to pay attention to when using car fuses. All power circuits in the car will first pass through fuses, from computer power to anti-theft, lighting must first pass through fuse maintenance. If there is no fuse maintenance disconnection effect, the entire car cannot be turned off when burning.　　Fuses are made of aluminum, and long-term use of connectors can also lead to poor air oxidation contact. The actual effect of modifying a silver connector fuse with a sound system is the best, but timely replacement of a new fuse is also a good method. If a more critical and effective fuse is replaced, it will have good main performance. Improving the efficiency of household appliances can save

what does a tv fuse look like.Factors affecting the lifespan of fuses and their evaluation

　　　　1. Factors that affect the lifespan of fuses:　　Working environment temperature:　　Excessive ambient temperature can damage the lifespan of the fuse. Delay type (slow melting type) fuses, such as tin ball type, begin to diffuse towards the metal wire when the temperature is about (150-170 ℃); The temperature at which the fusible metal wire of a quick fuse begins to undergo severe oxidation is approximately (175-225 ℃).　　Therefore, it is recommended that the delay type fuse fuse should not work above 150 ℃ for a long time, and the fast melting type fuse should not work above 175~225 ℃ for a long time.　　Pulse current:　　Continuous pulse impact can generate thermal cycling, leading to diffusion, oxidation, thermal stress, and even acceleration of the fuse. The fuse will gradually age with increasing pulse energy and frequency. Normally, it should be less than 20% to ensure that the fuse can withstand more than 100000 impacts.　　Other:　　For example, the length and cross-sectional area of t

plastic fuse board under stairs.Why does the resistance of patch fuses become large and constant?

　　　　The operating principle of a fuse is that an overcurrent causes the thermal balance on the melt to be disrupted. When the temperature of the melt rises to the melting point of the metal material, the middle part of the melt changes from solid to liquid. Due to the surface tension and gravity of the metal material suspended in the tube, the liquid part of the melt pulls away from both ends and sags downwards. The voltage caused arcing causes the melt temperature to continue to rise, further arcing and further distance pulling apart, Until the circuit is completely cut off. For SMD fuses, their operating principle is the same. However, due to different structural states, the surrounding of the metal melt is tightly surrounded by the polymer or ceramic materials of its substrate. Even the melted metal cannot contract towards both ends and can only rely on diffusion, infiltration, or absorption towards the surrounding materials. If the overcurrent disappears during this process (such a
