Technical Summary and
Application Guidelines
1.4.4 Temperature dependence of the Impedance
At 100kHz, impedance and ESR behave identically and
decrease with increasing temperature as the typical curves
show.
1.5 D.C. LEAKAGE CURRENT
1.5.1 Leakage current.
The leakage current is dependent on the voltage applied,
the elapsed time since the voltage was applied and the
component temperature. It is measured at +20°C with the
rated voltage applied. A protective resistance of 1000
is connected in series with the capacitor in the measuring
circuit. Three to five minutes after application of the rated
voltage the leakage current must not exceed the maximum
values indicated in the ratings table. These are based on the
formulae 0.01CV or 0.5µA (whichever is the greater).
Reforming of tantalum capacitors is unnecessary even after
prolonged storage periods without the application of voltage.
1.5.2 Temperature dependence of the leakage
The leakage current increases with higher temperatures,
typical values are shown in the graph. For operation between
85°C and 125°C, the maximum working voltage must be
derated and can be found from the following formula.

1.5.3 Voltage dependence of the leakage current.
The leakage current drops rapidly below the value corre-
sponding to the rated voltage V
applied. The effect of voltage derating on the leakage current
is shown in the graph. This will also give a significant increase
in the reliability for any application. See Section 3.1 for
details.
For additional information on Leakage Current, please
consult the AVX technical publication “Analysis of Solid
Tantalum Capacitor Leakage Current” by R. W. Franklin.
1.5.4 Ripple current.
The maximum ripple current allowed is derived from the
power dissipation limits for a given temperature rise above
ambient temperature (please refer to Section 2).
