　　　　1. Divided into: φ 2 φ 3 φ 4 φ 5 φ 6 and others.　　2. According to the fuse characteristics, it is divided into fast fuse type, medium delay fuse type, and delay fuse type. (It can also be divided into express and strong delay).　　3. According to the breaking capacity, it can be divided into low breaking type, high breaking type (and can also be divided into enhanced breaking type).　　4. According to safety standards (or usage regions), it can be divided into UL/cUL (North America) specifications, IEC (China, Europe, etc.) specifications, MIT/KTL (Japan/Korea) specifications, etc.　　In many electronic devices, fuses are indispensable. Since Edison invented the first plug-in fuse in the 1890s, which enclosed thin wires in a lamp holder, the types of fuses have become more and more diverse, and their applications have become more and more widespread. Here are some common knowledge on fuse parameters, selection, and application.　　The rated values and performance indicators of fuses are de

　　　　1. Determine the following parameters of the circuit:　　A Large working environment temperature b Standard working current c Maximum working voltage (Umax) d Maximum fault current (Imax)　　2. Select self restoring fuse components that can adapt to the ambient temperature and standard operating current of the circuit　　Use a temperature reduction {ambient temperature (℃) working current (A)} table and select the temperature that best matches the ambient temperature of the circuit. Browse this column to view values that are equal to or greater than the standard operating current of the circuit.　　3. Compare the high electrical rating of the selected component with the high operating voltage and fault current of the circuit　　Use the electrical characteristic table to verify whether the components you selected in step 2 will use the high operating voltage and fault current of the circuit. Check the high operating voltage and high fault current of the device. Ensure that Umax and Imax are g

The Development History and Trends of Fuses.resettable smd fuse

　　　　1、 Development History of Fuses　　In the 1880s, since Edison invented the light bulb and failed countless experiments on tungsten wire, it also opened up the development history of fuses. The success of light bulbs has also driven the development of fuses. With the development of society and the increasing strength of electrical appliances, the fuse industry has also experienced rapid development.　　The fuse industry in China started relatively late, but has developed rapidly. In 1950, China began to imitate the production methods of the Soviet Union to produce fuses, so the variety of fuses was relatively few, the structure was relatively simple, and the experimental methods were relatively backward. In the early days, the quality of fuses in China was not very good. Until the late 1970s, the emergence of color televisions promoted the development of the fuse industry, and the delay fuses used in color televisions began to move towards international standards. At this time, the fuse

Application of Self Recovery Fuses in Transformer Protection.solar panel fuse location

　　　　Power transformers are commonly used components in electronic products and are widely used due to their simplicity and ease of manufacture. There are two types of transformers: step-up transformers and step-down transformers (excluding impedance transformers and line matching transformers). They are also called linear transformers because they increase or decrease the original AC voltage proportionally and output it to the load for power supply.　　In application, step-up transformers are mainly used in instruments and meters; For the power supply of electronic products, the majority are actually step-down transformers. Structurally, the transformer is composed of stacked silicon steel sheets and primary coils. The coil is mostly wound with enameled copper wire, and now it is also used with enameled aluminum wire.　　For step-down transformers, their characteristics are: the primary input is 220V, the secondary output is low-voltage, the secondary current is small, the secondary curren
