Huaqiang Electronic network: Huaqiang electronic network is a comprehensive website for the procurement of electronic components and raw materials, providing related services for global IC chips, electronic components buyers, suppliers and manufacturers.
Now there are many more than wrong IC crossingsEasy website, some website reputation, qualifications are relatively good, and is a large trading website, such as Baidu's love procurement, Mr. IC and so on.
We go to more is Zhuoqiang IC network, Zhuoqiang network is a set of electronic components search, speed matching, procurement one-stop website, for electronic R & D engineers, procurement to provide fast and comprehensive electronic components search, only need to enter part of the product model or directly upload bom table quickly understand the immediate product inventory and price.
Yunhan core city is a well-known one-stop electronic components procurement mall, complete categories are the advantages of Yunhan core City. New typeJust Baidu the dog. The more information, the better. Brands, metrics. If it is a design, understand the basic parameter selection, there are more options. Go directly to the official website of the manufacturer, in addition to high-end components, manufacturers generally give free downloads.
There is a very powerful component data service company, SiliconExpert, and now there are agents of their data services in China, ickey seems to be able to free trial before, cross-replacement model query, mutually exclusive material data, life cycle prediction these seem to be able to find.
The flat currently available in the industryThere are a lot of Taiwan, the main difference is the content of the situation, my colleagues they introduced Datasheet5, the site covers a wide range of content, I have used more than 2 years, most of the components of the data can be found.
We are a professional website to check the code, to provide services for R & D maintenance units, to help you save time, more business. Want to know why? Welcome to this site.
1. IC/PDF Query: http:// This website provides a simple and easy-to-use query interface to help users query information by keyword, model, and description.
2, Huaqiang electronic network: Huaqiang electronic network is a comprehensive website for the procurement of electronic components and raw materials, for the global IC chip, electronic components buyers, suppliers, manufacturers to provide related services.
3, provide IC chip PDF data station query, as well as Chinese information, the website also supports real-time search.
4, ic chip information inquiry network: http://setIC (Integrated Circuit) card was invented in 1970 by French Roland Moreno, who for the first time put a programmable IC chip in the card, so that the card has more functions.
5, the overall is relatively perfect, the existing ICspec official website, ICspec wechat mini program, ICspec APP, library chip specifications are relatively complete, query, download, share, upload and so on. You can also browse semiconductor chip related information.
1, electronic components query: http://this website provides a comprehensive electronic components query service, including chips, modules, capacitors, resistors, diodes, transistors, etc.
2, there are many high-quality websites to learn hardware knowledge, such as CSDN hardware community, electronic enthusiast network, bit network, Huaqiang electronic network. These sites provide a wealth of hardware knowledge, technical articles, industry information and practice cases for beginners and professionals alike
3, learning components can go to Vicu electronic market network or go to the official websites of major electronic manufacturers such as ti, Mei Xin, Toshiba, Panasonic, NEC, National Semiconductor (nc), st and so on. Many but the premise is that you need to have an English basis, but some commonly used components of the Chinese PDF also have.
1, the PITCH (the distance from the center point of the part foot to the center point of the part foot) is different; SOT all denote small crystalsBody tube package. The number after the SOT only indicates that the sequence has no practical significance, and the number generally corresponds to different pin spacing. The SOT25 has three pins, the SOT-353 has four pins and the SOT-23-5 has three pins.
2. Start with the first row. First of all, the chips are marked, of course, excluding some domestic brands. If you don't recognize the sign, tell me something else. Look at the typing in the first row. Each chip model starts with a brand acronym. This is true of the IR, and then the model is IR2112 and this is the model, but not the full model, depending on the package.
3, to determine the IC card chip model, you can make a card Request to return the Request (u8mode) and Select_Card (void) to determine the card type basically can determine which manufacturer of which model.
