* Rated continuous working voltage (RCWV) shall be determined from
RCWV = Rated Power x Resistance Value, or Maximum RCWV listed above, whichever is less
** Recommended Circuit Board Design - If this device is anticipated to run at full continuous power then action
to improve the cooling should be taken. This can be a metal substrate, copper pad left under the chip, an
opening in the PCB or enlarged silver conductor pads each end.
