5. Reverse voltage (Temporarily) :

15% of the rated DC voltage at + 20°C

10% of the rated DC voltage at + 55°C

5% of the rated DC voltage at + 85°C

6. Rated Capacitance : 0.1µF to 330µF

7. Capacitance Tolerance : ± 20%, ± 10%,

8. Leakage Current in µA : Measured at + 20°C after 5

minutes. ≤ 0.008 x CR x UR or 0.5 µA, whichever

is greater

9. Dissipation Factor : at 120Hz and + 20°C

See table

10. Impedance : Measured at 100kHz and + 20°C

See table

11. Permissible AC Voltage Stress : The highest

permissible AC voltage for the respective frequency may

be taken from the brochure “General information“.

The values apply for + 20°C For higher temperatures,

the values have to be multiplied with the following
