最大脉冲爬升速率Maximum Pulse Rise Time(dv/ dt):若实际工作电压U比额定电压UR低,电容器可工作在更高的dv/dt场合。这样dv/dt允许值应为右表值乘UR/U. If the working voltage(U) is lower than the rated voltage(UR), the capacitor can be worked at a higher dV/dt. In this case, the maximum allowed dt/dt is obtain by multiplying the right value with UR/U. |
