Capacitance CR and ESRDC Measured by DC discharging method as described in “Measuring of Characteristics”. (2)

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
