◆降功耗曲线 Rated Power Derating Curve:
电阻器的额定功率,是指在环境温度低于70℃时,电阻器所能连续使用之最大功率值。当环境温度高于70℃时,额定功率由下图的降功耗曲线来决定。
The rated power of a resistor refers to the maximum continuous power that the resistor can handle when the ambient temperature is below 70°C. When the ambient temperature exceeds 70°C, the rated power is determined by the power dissipation curve shown below.
