Derating
￭
Surrounding air temperature derating
In the temperature range +45…55 °C (+113…131 °F), the rated output current is derated
by 0.5 percentage points for every added 1 °C (1.8 °F). The output current can be calculated
by multiplying the current given in the rating table by the derating factor
