Nowadays, cars generally come with USB 3.0 ports. In addition to overcurrent and overvoltage protection, sensitive electronic devices using high-speed interfaces such as USB and HDMI also require electrostatic discharge (ESD) protection. Three different types of circuit protection devices can help avoid these potential destructive events. PolySwitch polymer positive temperature coefficient (PPTC) devices can provide self-healing protection in USB applications. Placing the PolySwitch PPTC device on the VBUS port of the USB power supply can limit the current during short circuit events, help prevent damage caused by sudden short circuits, and help achieve UL60950 compliance. The design of USB 3.0 uses circuit protection devices to help prevent overcurrent (PTTC, left) and overvoltage (PolyZen, right) damage at the power port, as well as ESD (SESD device) events at the data port For overvoltage protection in USB 3.0 applications, PolyZen devices use a hybrid approach that integrate
In circuit applications, the application range of diodes is becoming increasingly widespread, among which TVS diodes and voltage regulator diodes are more common. Many people are not very clear about these two. Today, the editor leads everyone to re understand them. From a definition perspective, TVS diode is an efficient circuit protection device developed on the basis of voltage regulator technology. Its circuit symbol and appearance are the same as ordinary voltage regulator diodes; Zener diode, also known as Zener diode, refers to the phenomenon of using a pn junction to reverse breakdown state, and its current can change over a large range while the voltage remains basically unchanged, making it a diode that plays a stabilizing role. (Related reading: Principles and Introduction of Transient Suppression Diodes (TVS)) In principle, when the two ends of a TVS tube are subjected to instantaneous high-energy shocks, it can suddenly reduce its impedance at a very high speed (up t
1. Self recovery fuses are used in conjunction with lightning protection components at the power input end for lightning protection and overcurrent protection applications: In this application, the main purpose is to avoid overvoltage damage to related equipment caused by power voltage fluctuations and lightning current interference. (Related reading: What are the application fields of self recovery fuses?) 2. The application of self recovery fuses in multi branch power supply systems with a single power supply: In this application, it can solve the problem of the entire system being paralyzed due to damage to a single device. In this system, WHPTC can solve the problem of one device (such as a single user in a building intercom) being short circuited, which prevents the entire system from working properly. The ultimate goal is to timely protect and isolate faulty equipment from the system when a short circuit occurs, without affecting the normal operation of other devices. It can
Today, the Topband visited our factory for the annual factory audit. The company is a global leading provider of intelligent control technology, we have established a partnership with them for more than 15 years."
At present, China's automobile industry has entered a stage of high-quality development. Six major automobile industry clusters have been formed domestically, namely in the Yangtze River Delta, the Pearl River Delta, the Beijing-Tianjin-Hebei region, the Central China region, the Chengdu-Chongqing Western region, and the Northeast region. In order to accelerate the integration and innovation of the automotive industry supply chain, and to contribute to the construction of a manufacturing powerhouse, under the active promotion of the Guangdong Provincial Department of Industry and Information Technology, the "2023 Guangzhou International Integration and Innovation Exhibition for the New Energy Automobile Industry" with the theme of "crossing boundaries, deep integration, and reshaping the automotive industry chain" has emerged." XC Electronics(Shenzhen)Corp.,LTD participated in this exhibition as an outstanding supplier of fuses in the new energy industry.
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!"
