Maximum current I
max
The maximum RMS current for continuous operation
Maximum peak current î
The maximum current amplitude which occurs instantaneously during continuous operation.
The maximum peak current (Î) and the maximum rate of voltage rise (dV/dt)
max
on a capacitor are
related as follows:
Î = C · (dV/dt)
max
Maximum surge current I
s
The admissible peak current induced by a switching or any other disturbance of the system which is
allowed for a limited number of times.
I
s
= C · (dV/dt)
s
Maximum duration:
50 ms/pulse
Maximum number of occurrences: 1000 (during load)
Series Resistance R
s
The series resistance of a capacitor is the result of the resistive losses that occur in the electrodes, in
the contacting and in the inner wiring.
The series resistance R
s
generates the ohmic losses (I
2
· R
s
) in a capacitor, and it is largely
independent of frequency.
Self-Inductance L
self
The self-inductance is produced by the inductance of the terminals and the windings.
With Self-Inductance, it is possible to determine the Resonance Frequency.
