Power factor correction capacitors are highly sensitive to harmonics since the capacitive im-pedance is inversely proportional to frequency. This means that, when supplied by a distorted voltage, the capacitors draw an overcurrent due to harmonics that could seriously damage them, especially if there is a series or parallel

Voltage limits. Every capacitor has a limit of how much voltage you can put across it before it breaks down. Be careful to give yourself a little extra headspace with the voltage limit to account for any potential voltage spikes. Reversed voltages. Some capacitors do not care about voltage polarity but some, particularly electrolytic capacitors, cannot accept reversed
Electric double-layer capacitors (now supercapacitors) were invented in 1957 when H. Becker developed a "Low voltage electrolytic capacitor with porous carbon electrodes". [17] [18] [19] He believed that the energy was stored as a charge in the carbon pores used in his capacitor as in the pores of the etched foils of electrolytic capacitors
