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.
