Libraries operate on a simple concept: store component data for use in projects. When you add components into a project from the Manufacturer Part Search panel in Altium Designer, or you download a component from a component website, you’re taking that component data and placing it into a library so that it can be used in your design. All component data is stored somewhere in a library, whether it’s in a project folder on your local computer, or in the cloud on Altium 365. Sometimes, when another designer shares a project with you, they won’t just share schematics and PCB files, they will also share libraries. All capacitors are Murata – because it was easier to scrape one manufacturer without getting thousands of duplicate value parts.If you look at PCB design forums, sites like stackexchange, or design guides on the internet, you’ll often see mentions of libraries. They all contain similar parameters as the resistors. There are 4,739 capacitors in 6 different libraries split up according to package size: 0201, 0402, 0603, 0805, 1206, 1210. I scraped the data from Digi-Key to create these libraries and thus they contain a significant number of parameters that you can use for your BOM generation. The resistors are split up into 6 different IntLibs according to package size: 0201, 0402, 0603, 0805, 1206, 2512. There are 6,029 resistors, all are Panasonic ERJ series. Panasonic ERJ resistors libraries download I’ll start here by giving you the libraries I generated and I’ll make another post about how I generated them. The database can take many forms such as an Excel spreadsheet, Microsoft Access database, or in theory any SQL or ODBC source. I wanted to figure out on my own how I could scrape data from Digi-Key and (almost) automatically create part libraries.Īltium Designer has a powerful feature called Database Libraries which take an external database and link entries to a schematic symbol and physical footprint. I realize you can get many of these parts from Altium or other third parties. I generated several libraries for Altium (or Circuit Studio) using Database Libraries which I then exported to IntLibs.
