I took advantage of the generous offer of Bob KE6F for SMT components in exchange for an SASE. Thank you, Bob! I need to learn how one can identify the various components. For example, I found some 16 pin devices marked 2333, 12, and then 9932 at right angles to the first two markings. I assume that one of these groups, perhaps the last one, is a date code. I have tried Google with no luck. One of my neighbors works for a company that makes digitally-controlled lighting and he has been bringing me discarded PCBs that are loaded with SMT components and most of them have similar markings. Is there a source for information that would help me to identify some of these devices? Thanks and 73, Dave K1YHR.

Google "smd codes"; you will find a lot of information including The SMD Codebook.
