　　The size of a 220 volt fuse should be calculated based on the power consumption of the device. According to Ohm's law, current equals power divided by voltage. Taking a 600 watt iron as an example, its current is approximately 2.8 amperes. If the current is too high during startup, multiply it by 1.5 and choose a 5 ampere fuse

　　A 220 volt electricity requires a fuse, and the current is different. You need to choose the fuse according to the actual electrical appliance you are using. Generally, for a 1 kW appliance, a fuse of 5 amps or more is needed, and so on. For a 2 kW appliance, a fuse of 10 amps or more is needed. The higher the power of the electrical appliances used, the greater the current of the installed fuses. This requires determining the appropriate fuse size based on the actual overall power consumption.

　　　　In the past few years, surface mount fuses have been the most valuable variety among small fuses, but the price competition they face is also fierce. The average unit price of the product has decreased by 20-30%. In recent years, while surface mount fuses have gained widespread popularity, they have also made continuous breakthroughs and innovations in technology.　　From the perspective of global fuse production distribution, a large proportion of electronic assembly factories are located in China, with over 40% of actual applications in China. The main market of surface mount fuses is in Asia, and is concentrated in Chinese Mainland, Taiwan, Japan and South Korea. Many Japanese and South Korean companies also have factories in China, making China an important market for surface mount fuses.　　The actual annual consumption of surface mount fuses in the former Greater China region (including Japanese, Korean, Hong Kong and Taiwan funded factories in Chinese Mainland) accounts for abou

　　Four elements to avoid when using self recovering fuses (PPTC)　　One: Avoid the significant mechanical stress of self recovering fuse chips　　Fuses will undergo thermal expansion of the polymer itself during operation. If under certain mounting conditions, the two ends of the device chip are subjected to significant pressure, compression, distortion, bending, etc., the thermal expansion phenomenon will be limited, thereby affecting the electrical function of the device, which will cause the protective device to be unable to operate under fault conditions.　　Secondly, to avoid short circuits in non packaged devices　　Is there any conductive object contamination between the edge of the self-healing fuse device and the bracket when using a non encapsulated PPTC device. This non encapsulated conductive object pollutant can cause faults such as oxidation and combustion.　　Thirdly, several points to pay attention to when soldering components　　When wave soldering or reflow soldering is required,

　　Current Fuses for Different Voltages　　Current fuses are designed to operate at different voltages to meet the diverse requirements of electrical systems. For low-voltage applications, such as in household electronics and small appliances, the current fuses are typically rated for voltages ranging from a few volts to around 120 volts (in some regions). These fuses are designed to protect the relatively low-voltage circuits from overcurrent and short-circuit events. They are often smaller in size and have lower current ratings compared to fuses used in higher voltage systems. For example, a fuse used in a mobile phone charger may be rated for 5 volts and a few amperes. It is designed to quickly interrupt the current if there is a fault in the charger circuit to prevent damage to the phone or the charger itself. In medium-voltage applications, such as in industrial machinery and some commercial electrical systems, the voltage range of the current fuses is usually between 120 volts and 6

Self recovery performance and working process of self recovery fuses

　　　　Traditional fuses are installed in circuits. When an overcurrent occurs due to a fault or abnormality in the circuit, the fuse itself melts to cut off the current and protect the circuit. However, due to the fact that traditional fuses can only protect once and need to be replaced if burned out, some products still cannot resume operation after troubleshooting or abnormal overcurrent disappears. As a new type of overcurrent protection device, the self recovery fuse has the function of automatic recovery, which can meet the performance requirements of similar applications.　　The self recovery fuse is connected in series in the circuit, and under normal circumstances, it is in a low resistance state to ensure the normal operation of the circuit; When a circuit experiences a short circuit or abnormally high current flows in, the self-heating of the self-healing fuse increases its impedance and limits the current to a sufficiently small amount, providing overcurrent protection.　　Self re
