20 years ago, Xucheng Electronics (Shenzhen) Co., Ltd. was officially established On July 8, 2002,! Over these many years, Xucheng colleagues and customers have accompanied the company in its growth journey, witnessing its evolution from small to large, from strength to strength, weathering challenges together. Xucheng is currently undergoing transformation, innovation, and development, which remain the eternal themes of the company ! We believe that Xucheng's future will be even better!"
Many users have told me about buying printers, but when asked which one they want to buy, they can't tell. Before purchasing a printer
Overall, as an important basic electronic component, the market supply and demand situation of fuse products has always been relatively stable, and the price trend is relatively stable without significant fluctuations. Benefiting from the rapid development of 3C products such as computers, communication, and consumer electronics in recent years, the competition in the conventional fuse market has become increasingly fierce. This has also led some manufacturers to target the "blue ocean" market of customized fuses and develop a series of unique fuse products tailored to the special needs of different end users. The key function of fuses is to fuse in a timely manner in case of overcurrent, in order to protect people, equipment, and prevent fires. "Relevant fuse professionals said," Due to the increased requirements for safety performance, there have been some changes in the relevant safety standards IEC60127 recently. The revised IEC60127 has improved the flame resistance of the pl
Ceramic gas discharge tubes are the most widely used switching devices in lightning protection equipment. Whether it is for lightning protection of AC and DC power supplies or various signal circuits, they can be used to discharge lightning currents into the ground. Its main characteristics are: high discharge current, small interpole capacitance (≤ 3pF), high insulation resistance (≥ 109 Ω), high dispersion of breakdown voltage (± 20%), and slow reaction speed (the fastest is 0.1-0.2 μ s) . According to the number of electrodes, there are two types of discharge tubes: bipolar discharge tubes and bipolar discharge tubes (equivalent to two bipolar discharge tubes connected in series). Its shape is cylindrical, with two structural forms: with and without leads (some also have protective cards for short circuits in case of overheating). A gas discharge tube consists of two electrodes enclosed at a certain distance in a ceramic tube filled with inert gas. Its electrical performance ba
As an important type of basic electronic component, the supply and demand situation of the fuse product market has always been relatively stable, and the price trend has also been relatively stable. Benefiting from the high and rapid development of 3C electronic products and equipment such as computers, communication, and consumer electronics in recent years, some manufacturers/suppliers have begun to target the emerging market of customized fuses and develop a series of fuse products that meet the special needs of different end users and have their own characteristics. At present, there are three requirements for the development of the fuse industry in the era, and customers need to know when purchasing. 1. Upgrade safety regulations to improve safety requirements The key function of a fuse is to fuse in a timely manner in case of overcurrent, in order to protect people, equipment, and prevent fires. Due to the increased requirements for safety performance, there have been some
If the fuse can be removed from the circuit, it can be a visual fuse to determine whether it has burned out; The simplest method to determine whether a fuse is a continuity test is to blow other materials. Quickly test with a multimeter to determine if it is working properly, by hearing a beep and touching the wires together, or seeing a 0 ohm reading. After confirming that the circuit power is turned off, place the leads at both ends of the fuse. If you hear the same beep and the resistance reading of the multimeter is very low, then the fuse will not blow. If you don't hear the beep and the meter reading is OL, the fuse will blow. Take reasonable preventive measures to stay away from dangerous voltages. Supply the power circuit and switch to the multimeter voltage measurement mode. Ensure that DC circuits are selected for DC and AC circuits are selected for AC Connect the multimeter leads on both sides of the fuse. If the indicated voltage is small or even not, the fuse is intact
