0 ohm jumpers also normally have a current rating listed on the data sheet.
For Dale's CRCW series 0603 0 Ohm jumper, the current limit is 1A. The max
resistance listed for that package is 0.05 ohms, and Dale lists the max
power at 1/16W, which corresponds to a little over 1A in current. I don't
think there's anything wrong with doing it this way.

<<What will be the maximum current allowed for the resistor?>>
I think manufacturers specify a maximum resistance value for a
so-called '0 ohm' resistor. For instance, a '0 ohm' jumper could be
specified as having an Rmax of 0.01 ohm. For a power rating of 0.1 W, hence,
it could take a max current of 3 A or so.

Subject: [SI-LIST] : maximum current for a 1/10Watt , 0 ohm
jumper?
Hi All,
�
I saw some people use one 0 ohms 0.1W 0603 resistor as jumper to
connect�5V to chip's power pin.��Is it�a proper way?� What is the
disadvantage?� What will be the maximum current allowed for the
resistor?�Since the resistor value is very small, does it mean�a�large
current is allowed to flow through the resistor�to cross the�0.1w
limitation?
�
Appreciate your comments..
