Intelligent fuse.temperature switch thermostat thermal protector fuse

　　　　intelligent　　For most asynchronous rectifier boost switching converters that use inductors, there is a DC path between the input and output. The existence of this path can have two adverse consequences: firstly, once the output short circuit or severe overload time exceeds a few hundred milliseconds, it will cause the diode (usually Schottky diode) to overheat and damage; Secondly, when for some reason, such as human shutdown, the switching oscillation circuit stops working, and there is still voltage at the load end, which is only one diode lower than the input voltage drop, the output will still consume energy. In addition, if the residual voltage is lower than the steady-state operating voltage range of the load, it will put the circuit in an uncertain state.　　For applications where the output current is relatively small (less than 5A), using a single-chip current mode controller and high-end current sampling technology can effectively solve both of the above problems. In these

Analysis of the Future Development Status of Fuses.power probe fuse voltage drop chart

　　　　This is an information age, a major era in which smartphones and other smart mobile devices are thriving. People are no longer satisfied with their phones being able to only make phone calls and text messages, and even begin to be dissatisfied with some of the existing intelligent functions. With the prevalence of mobile 4G networks and the expansion of people's visual and tactile senses, smartphones have continuously acquired new technologies, truly achieving rapid breakthroughs and development.　　On this basis, we found that the hardware configuration of mobile phones is getting higher and higher, and it was not long before computers entered the four core era, and mobile phones also followed closely into the four core era; As the size increases, a 5-inch screen is no longer uncommon, and there is a trend towards larger screen sizes. In the near future, there will be a blurry boundary between smartphones and tablets that is difficult to distinguish.　　But the problem lies here as we

What are the types of Thermal cutoff.thermal protector recessed light

　　　　Temperature controlled fuses are mainly used for circuit maintenance. When the temperature of household appliances exceeds the rated temperature of the fuse, they will automatically open the circuit breaker to avoid damage caused by excessive temperature. According to different composition methods, which types can temperature controlled fuses be classified? How to apply it correctly? Let's take a look!　　1. Organic type temperature control fuse.　　It consists of moving contact points, melt, and torsion springs. The principle is to improve the fluidity of the surrounding environment during operation, melt, weaken the ductility of the torsion spring, cause the left line to separate from the moving contact point, disconnect the current, and disconnect the circuit.　　2. Ceramic tube type temperature control fuse.　　This type of fuse is famous for its insulated porcelain tube. During operation, the temperature increases, causing the mixture to evaporate. After the dissolution point, the int
