At continuous power dissipation the dimensions of solder-pads have to secure sufficient heat-conduction.

3)
Power Mode: The temperature of the resistor element is higher than in standard mode! Higher power rating requires an
adequate heat removal (e.g. increased solder pads or Copper thicknesses) The user has to guarantee, that solder joints will not
run over their load limit. The resistor must not exceed the specified operating temperature range.
