端子部温度负荷减轻特性曲线的说明 Introduction of the derating curves based on the terminal part temperature ●背景 ●Background Recently, the miniaturization, high power density and high temperature of the usage environment for the automotive devices have advanced. And requests o f r resistors to conform the high temperature is increasing. Figure 1 is the 1 derating curve based on the terminal part temperature and this is introduced to realize these requests for the surface mount resistors safely. Rated terminal part temperature is the maximum terminal part temperature of the surface mount resistor at which the rated power may be applied continuously including the temperature rise by self heat generation. 100 Maximum 100 ) Terminal part % ( ) o Temperature i
