Datasheet

The leakage current is dependent on the voltage applied, the
elapsed time since the voltage was applied the component temp.
it is measured at +25℃ with the rated voltage applied. the rated
d.c voltage shall be applied to terminals across the test capacitor
Cx. by the method as shown below.
5-1 Temperature dependence of the leakage current
when operating at high temperature range from 85℃ to 125℃,
the operation shall be carried out at a derated voltage or less.
Derating voltage Vt at any temperature between 85℃ and 125℃
shall be calculated by the following equation.
when V
t : Derated voltage at any temp.
V
r : Rated voltage
V
d
: Derated voltage at 125℃
5-2 Leakage Current vs Rated voltage
The leakage current drops rapidly below the value corresponding
to the rated voltage VR When reduced voltage are 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.
