Terms and formulas

Maximum current Imax

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 Is

The admissible peak current induced by a switching or any other disturbance of the system which is allowed for

a limited number of times.

Is = C · (dv/dt)s

Maximum duration:

50 ms/pulse

Maximum number of occurrences:

1000 (during load)

Series Resistance Rs

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 Rs generates the ohmic losses (I

2.Rs) in a capacitor, and it is largely independent of

frequency.

Self-Inductance Lself

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.
