Max current for 0\$\Omega\$ resistor
Well there's no such thing as a zero ohm resistor, not a room temperature anyway. If you find one call me I'll invest :)   The datasheet says 805 Jumpers are &lt; 50m\$\Omega\$, and I don't see any quoting of 5% for that number.  Later it says it's 805 package can dissipate .125W @ 70C.   So if \$P = i^2R\$ then the max \$i\$ would be about 1.5A.  Of course you may want to de-rate that for your application.
