Ratings Design and specifications are subject to change without notice. Carefully check the specification sheet supplied with the product before using or ordering it. Item Rated power Conditions Specifications Power must be derated according to the power derating curve in Figure 1 when ambient temperature exceeds 70°C. 0.10W (1 / 10W) at 70°C 100 POWER LOAD (%) 80 60 40 20 0 −55 0 70 100 155 AMBIENT TEMPERATURE (°C) Fig.1 Rated voltage The voltage rating is calculated by the following equation. If the value obtained exceeds the limiting element voltage, the voltage rating is equal to the maximum operating voltage.
