　　　　According to size, it can be divided into small, medium, and large car fuses. The current includes: 1A, 2A, 3A, 5A, 7.5A, 10A, 15A, 20A, 25A, 30A, 35A, 40A, 50A, 60A, 80A, 100A; In plug-in car fuses, each color represents a different current of the car fuse. Certification includes UL, CSA, and ROHS. The types can also be divided into: MIN-N 2A Lt.grey, 3A Violet, 4A Pink, 5A Tan, 7.5A Brown, 10A Red, 15A Blue, 20A Yellow, 25A Natrual, 30A Green, 35A Pupel, 40A Orange/32V plastic zinc alloy 11x4x11mm　　ATY-N 2A Lt.grey, 3A Violet, 4A Pink, 5A Tan, 7.5A Brown, 10A Red, 15A Blue, 20A Yellow, 25A Natrual, 30A Green, 35A Pupel, 40A Orange plastic zinc alloy 19x5x18.5mm　　MAX-N 20A Yellow, 25A Natrual, 30A Green, 35A Pupel, 40A Orange, 50A Red, 60A Blue 70A Tan, 80A Natural, 100A Violet/32V

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

Main parameters of Thermal cutoff.thermal controller hardware

　　　　Thermal cutoff, also known as thermal fuse, is a new type of electrical overheating protection element. This component is usually installed in easily heated electrical appliances. In case of electrical failure and heating, when the temperature exceeds the abnormal temperature, the Thermal cutoff will automatically cut off the power supply to prevent electrical fire. In recent years, most of China's household electrical appliances with the main function of heating, such as Rice cooker, electric buckets, electric furnaces, etc., have been installed with Thermal cutoff. However, in case of internal failure of parts, Thermal cutoff can cut off the power supply in time to prevent further damage to the appliances and end the fire caused by this. Like the familiar fuse, the Thermal cutoff is usually only used as the power channel on the circuit. If it does not exceed the rated value, it will not open circuit and will not have any impact on the circuit. The circuit will only open when an e

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

Explanation of 600V 0.5A plug-in fuse specifications and models.resettable fuse smd

　　　　The corresponding model of the brand 600V 0.5A plug-in fuse is A600-500, which is a recoverable fuse that plays an overcurrent protection role in the circuit. This model of fuse is a fast melting fuse that maintains a current of 0.5A, operates with a current of 1A, a maximum voltage of 600V, and a maximum voltage of 3A. The power generated by the fuse during operation is 5W. When the current passing through the fuse is 2.5A, the fuse will operate within 15S, At this moment, the minimum internal resistance of the fuse of the material number is 2.5 Ω, and the internal resistance after one hour of welding on the machine is 7 Ω. The above data are all for at room temperature of 25 ℃. We all know that the parameters of fuses can be affected in different working environments. If the rated current at 25 ℃ is 0.5A at room temperature, then at 40 ℃, the maintenance current of the fuse is only 88% of that at room temperature, which is 0.44A; At a temperature of 50 ℃, the fuse of this materia
