The modern era of aluminum electrolytic capacitors
Early electrolytic capacitors consisted of an Al electrode in a "bath" of electrolyte. The resistance of the electrolyte resulted in a relatively high equivalent series …
Principles: Aluminum electrolytic capacitors | ELNA CO., LTD.
Aluminum electrolytic capacitors are made by layering the electrolytic paper between the anode and cathode foils, and then coiling the result. The process of preparing an electrode facing the etched anode foil surface is extremely difficult. Therefore, the opposing electrode is created by filling the structure with an electrolyte.
Aluminum Electrolytic Capacitors
Differences in normal DC leakage current among capacitors can cause voltage imbalances. The use of voltage divider shunt resistors with consideration to leakage currents can prevent capacitor voltage imbalances. NOTE : Please do not use in the series in the case of conductive polymer hybrid aluminum electrolytic capacitor.
