The device has been discontinued, how to find replacement materials? There are too many parameter categories, how to grasp the key points? There are many pages of search results, who should you choose? Are you worried about device selection? Of course, this is also a problem for most engineers! Therefore, Digi-Key, who understands you best, has specially launched a heart-warming tutorial. After a few minutes of explanation, you will become an expert in product selection. The tutorial not only provides solutions to the problems listed above, but also teaches you step by step how to use Digi-Key's powerful parameter index function. Choose what you like, and you no longer have to search for it through Baidu.
