The ultimate SMD marking codes database

Due to the small size of most SMD components, manufacturers are not able to write the full part number on the case. They use instead a marking code typically composed of a combination of 2 or 3 letters or digits. When repairing an unknown electronic board, it becomes so difficult to know what is the exact type of a given component. This database allows to quickly find the part number of a SMD component when you have only the marking code.
