Pulse handling capability
"dV/dt" represents the maximum permissible voltage change per unit of time for non-sinusoidal
voltages, expressed in V/µs.
"k₀" represents the maximum permissible pulse characteristic of the waveform applied to the
capacitor, expressed in V²/µs.
Note:
The values of dV/dt and k₀ provided below must not be exceeded in order to avoid damaging the
capacitor.
