What happens when a cathode foil is applied to aluminum electrolytic capacitors?
When high slew-rate loads such as a rapid charge-discharge are applied to aluminum electrolytic capacitors, the various electrochemical reactions on the cathode foil bring the gas generation and the capacitance reduction of the cathode foil.
What is a general-purpose grade aluminum electrolytic capacitor?
Aluminum electrolytic capacitors for general applications are called "General-Purpose Grade" (GP) in IEC publications. The international standard for aluminum electrolytic capacitors is IEC 60384-4.
