Friends, I present to your attention a reference application on the SMD codes of popular semiconductor devices: - diodes; - transistors; - various microchips. The database contains descriptions of more than 418 thousand devices, including pinout terminals on the housing, as well as a brief description of their operation parameters. I tried to make it as light as possible (up to 15 MB), fast and convenient (full-text search). I am waiting for your feedback, ratings and constructive criticism on Google Play. Also, if you have additional reference material, I'm ready to try adding it to the app too :)
