Power Derating Curve
For resistors operated in ambient temperatures above
70 °C, power rating shall be derated in accordance
with the figure on the right.
Ratings
(1) Rated Continuous Working Voltage (RCWV) shall be de ter mined from RCWV=
√
Power Rating × Resistance Value, or Limiting Element Voltage listed
above, whichever less.
(2) Overload (Short-time Overload) Test Voltage (SOTV) shall be determined from SOTV=2.5 × RCWV or max. Overload Voltage list ed above whichever less.
