General technical information
Capacitance
The DC capacitance is the decisive factor for the energy yield. This characteristic is
approximately 1.2 times the AC capacitance. Since the loss angle can only be determined using
alternating currents and the AC capacitance is measured together with this value, it is usual to
state the AC capacitance. The values are measured at a frequency of 100 Hz.
Leakage current (measuring conditions)
The leakage current value limits quoted by EPCOS apply to the capacitors in new condition.
When the leakage current is determined, the current is measured after the capacitor has been
connected, for a period of five minutes, via a 1 kΩresistor to a stabilized power supply set to the
rated voltage.
Temperature
The attached diagram shows the temperature dependence of the leakage current. In order to
prevent thermal instabilities, switching loads that can lead to overtemperatures of more than 15 K
shall not be applied.
