Electrolytic Capacitor - Dc Polarized Design, Rated Voltage Limitations, Reverse Polarity Protection, Ideal For Low Voltage Applications

Electrolytic capacitors for DC applications require polarization.
Confirm the polarity before use. The circuit life may be shortened or the capacitor may be damaged if insert in reversed polarity. For use on circuits whose polarity is occasionally reversed, or whose polarity is unknown, use non-polar capacitors. Also note that the electrolytic capacitors cannot be used for AC applications.
Do not apply a voltage exceeding the capacitor's voltage rating.

If a voltage exceeding the capacitor's voltage rating is applied, the capacitor may be damaged by increased leakage current. When
using the capacitor with AC voltage do not exceed the rated voltage
note: the life of the charger & discharge capacitor relate to the discharge time s per minute, the design of the circuit and the discharge impedance.
