Maximum peak current
Non-repetitive current for maximum 1 s at specified operating temperature.
Maximum operating voltage (refer to derating table) must not be exceeded.
Usually to be tested with constant current discharge from UR to 0.5 x UR.
Maximum current should not be used in normal operation and is only provided as reference value.
Leakage current ILMeasured at UR. Capacitor is charged to the rated voltage at 20 °C. Leakage current is the current at specified
time that is required to keep the capacitor charged at the rated voltage.

MEASURING OF CHARACTERISTICS
CAPACITANCE (C)
Capacitance shall be measured by constant current
discharge method.
- Constant current charge with 10 mA/F to UR
- Constant voltage charge at UR
- Constant current discharge with 10 mA/F to 0.1 V
Fig. 3 - Voltage Diagram for Capacitance Measurement
Capacitance value CR is given by discharge current ID, time
t and rated voltage UR, according to the following equation:
EQUIVALENT SERIES RESISTANCE (ESRDC)
- Constant current charge to UR
- Constant voltage charge at UR
- Constant current discharge to 0.1 V
Statements about product lifetime are based on calculations and internal testing. They should only be interpreted as estimations. Also due to external factors, the
lifetime in the field application may deviate from the calculated lifetime. In general, nothing stated herein shall be construed as a guarantee of durability.
