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.
