Default SMD-- how to ID ?

I've avoided SMD components for years, but I just inherited some.

Are there standards regarding the package labeling on these tiny parts?

Are there any good sites to look-up the markings?
It is really strange that there is so little ID info out there.

A whole lot of SMD passive components, especially caps, are not even marked these days. Sad, but true.

Thanks for the link, digitaljunkie.

Unfortunatly, I could not decipher many of the parts....not enough info to be useful to the DIY'er, especially at those sizes.


example.....8 pin SOIC labeled :

D205
0046Y

by Infineon

The Infineon site does not even return results when the SMD part # is entered in their search engine. I don't think the other manufacturers return SMD results either, do they ?

Less ans less leaded parts these days.....I guess soon, leaded parts will all be rare, and sourced from overstock.
