Markings: Capacitors are marked with the following information
Rated capacitance, Rated voltage, product number, name of manufacturer, UL symbol, positive terminal, negative terminal and warning marking
>
Mounting Recommendations:
Cells are designed to be soldered into series or parallel strings. Components should not be operated outside recommended limits. Parts can be ordered without tabs.

Additional Technical Information:
Pd = (0.12 x E2/Rd)/M
E = charge voltage (UR) Rd = internal resistance (DC)
T=DRthIc2Rd
D = duty cycle Ic= continuous current
M = capacitor weight (kg) V = capacitor volume (l)
