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
