Hi!
Just to let the OP know so he's aware of this, datasheets often DO give a maximum current rating of a zero–ohm jumper, but this is purely to avoid excessive temperature rise at their end–terminations and over their bodies as a whole, in order to prevent damage to the pcb they're used on!
There are also thro' hole zero ohm links, which have a beige body and a single central black band coding them as zero, again they're intended as useful crossover devices on single–sided layouts – don't forget "pick–and–place" machines can't handle little pieces of wire!
The idea of using a very low or very high ohmic value component as a "dummy" is a very old one that predates surface–mount construction by many decades, black–and–white TV sets used to have things that look like carbon–composition resistors coded with four black rings – this indicated a "dummy" component that could be used as a former for small peaking or correction chokes in video or I.F. circuits, for instance!
