[PDF]2018-5-17 To accomplish that, highly etched cathode foils are necessary. Nonpolarized electrolytic capacitors use the same foil for anode and cathode ( C A = C K ) Therefore the capacitance of these capacitors are given by C G = 0,5 * C A. It is obvious that a nonpolarized electrolytic capacitor needs two times the space of a polarized capacitor. 2.
