This site was the most comprehensive website for smd component markings and part numbers and unfortunately it has disappeared recently.
I was wondering if any of our Russian friends might know what happened to it:

Putin had him arrested on a whim. Alegedly.
I confirm this was a really good site for smd markings ! (and I sub to this thread as well to know the answer ?)
The site saved my hide many times ID'ing SMT parts. I hope it comes back, or someone did a siterip.
It seemed to be piggybacking on the city of Tomsk website.
