jb Capacitors -- Pulse operation
Capacitors loaded with pulses with fast rise or fall times (high dU/dt) will be exposed to high current pulses. In order not to overload the internal connections the current must be limited. The current limits for a specifc type are dependent upon:
- Amplitude and form of the pulse
- Rated voltage of the capacitor
- Capacitance
- Geometrical configuration of the winding
dU/dt = UR/(R x C)
UR = Rated voltage
R = Discharge resistor
C = Rated capacitance
