How to identify this particular SMD component?
It is a "zero ohm link".

You can find them listed in the resistors section of a vendor's parts catalog.

It is typically used to turn on or off configuration options on the circuit board.  The "0" marking is intended to make this stand out among a group of actual resistors.

They come in many sizes and even through hole versions.  It is possible that this one is large in order to make hand-soldering easier.
