in order to compare the different characteristics of the different electrolytic capacitor types, capacitors with the same dimensions and of similar capacitance and voltage are compared in the following table. in such a comparison the values for esr and ripple current load are the most important parameters for the use of electrolytic capacitors in modern electronic equipment. the lower the esr, the higher the ripple current per volume and better functionality of the capacitor in the circuit. however, better electrical parameters come with higher prices.
