Maximum Pulse Rise Time (dV/dt)
If the working voltage (U) is lower than the rated voltage (UR), the capacitor can operate at a higher dV/dt. The allowable dV/dt value should be obtained by multiplying the right table value with UR/U.
| UR(V) | dV/dt(v/s) for P=7.5 | dV/dt(v/s) for P=10.0 | dV/dt(v/s) for P=15.0 | dV/dt(v/s) for P=22.5 | dV/dt(v/s) for P=27.5 |
