1.
This is the maximum voltage that may be continuously supplied to the resistor element, see “IEC publication
60115-8”

R-value might be variance depend on soldering conditions and please consider this influence before use milli-ohm
resistors, and strongly suggest use the recommend solder pad to design your circuits
