Derating Recommendations, maximum continuous voltage
The maximum continuous voltage Vcont is the maximum permissible voltage at which the capacitor
can be continuously operated. It is a direct current voltage, or the sum of the basic DC voltage
plus the peak value of the superimposed AC voltage.
The maximum continuous voltage depends on the ambient temperature (see figure below). Within
the temperature range of -55 °C to +85 °C, the rated voltage is equal to the maximum continuous
voltage.
In the temperature range between +85 and 105 °C the maximum continuous voltage must be
reduced linearily from the rated voltage to 4/5 of the rated voltage (Derating). Operation below the
maximum continuous voltage has a positive effect on the capacitor´s reliability.

voltage) versus temperature

Temperature dependence of the capacitance
The capacitance of an electrolytic capacitor varies with the temperature (positive temperature
coefficient). The amount by which it varies depends on the specific voltage and capacitance
value.

Dissipation factor
The dissipation factor tan δ increases with frequency and tends to very high values at
near-resonance frequencies. The figures below show the typical behaviour of the dissipation
factor.

Basic
Leakage current
When a direct voltage is applied to electrolytic capacitors, a low, constant current will flow through
any capacitor. This so-called leakage current Ilk is a function of the voltage as well as of the
temperature. (Graphs are shown below).
The absolute value of the leakage current of an electrolytic capacitor is determined by defects of
the dieletric. The (exclusive) usage of high-purity tantalum powder as raw material results in a low
total amount of defects and thus in a low leakage current level.

Taping
Chip capacitors are taped and reeled in accordance with IEC 60286-3. Sizes B is supplied in
8-mm blister tapes, sizes D and V in 12-mm blister tapes. The position of the positive pole (+) is
shown in the dimensional drawing below.
Caution! If any capacitors are left over in the tape after placement, sparks may be generated
when the tape is cut into pieces. This may impair or damage process equipment.
