Package Code Search
These are common as dirt. But all appear to be proprietary. They really shouldn't be called SMD marking codes, as there are plenty of other components that need to be looked up.
- http://www.smdmark.com/en-US/search/code?id=AAA - This one you can use without JS, just add the code where appropriate in the URL. Some results require logging in...
- http://markingcodes.com/search/c/AAA - Same as previous for adding code. Shows a bit more results, but requires JS to change pages.
- Where is the public wiki search? Too much greed, too many people trying to monetize something which should just be a database.
