250 | 270 | 660 | 560 | 310 | 130 | 110 |
400 | 440 | 900 | 780 | 600 | 300 | 130 |
630 | 550 | 1500 | 1200 | 900 | 400 | 200 |
1000 | -- | -- | 2200 | 2000 | 800 | -- |
1600 | -- | -- | -- | 4500 | 1800 | -- |
2000 | -- | -- | -- | 9500 | 4500 | -- |
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 dV/dt is obtain by multiplying the left value with UR/U.
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允许值应为左表值乘以UR/U。
