Note: *Package Power Temperature Derating Curve
Note: **Resistors shall have a rated DC or AC(rms) continuous operating voltage
corresponding to the power rating, as calculated from the following formula
Where V : Rated voltage (V)
V=
PxR
P : Rated power (W)
R : Nominal resistance ()
If the voltage so obtained exceeds the maximum operating voltage, this
maximum voltage shall be the rated voltage.
