Pulse handling capability
"dV/dt" represents the maximum permissible voltage change per unit of time for non-sinusoidal
voltages, expressed in V/
µ
s.
"k
0
" represents the maximum permissible pulse characteristic of the waveform applied to the
capacitor, expressed in V

s.
Note:
The values of dV/dt and k
