Answer: Aluminum electrolytic capacitors (electrolytics) are widely used in power supply applications requiring high capacitance in energy-dense, small-volume packages having very low equivalent series resistance (ESR).
Answer: Today's aluminum electrolytic capacitors have longer shelf life, usually around 2 years, as compared to their predecessors. For aluminum electrolytic capacitors, the changes in ESR, capacitance, and leakage current are caused by chemical reaction between the aluminum oxide film and the electrolyte.
Answer: They are commonly used as filtering devices in various power supplies to reduce the voltage ripple. When used in switching power supplies, they are often the critical component limiting the usable life of the power supply, so high quality capacitors are used in this application.
Answer: What's Inside an Electrolytic Capacitor? The aluminium electrolytic capacitor consists of two foils sandwiched between absorbent paper, and wound tightly into a cylinder. The anode, is composed of pure aluminium foil with aluminium oxide formed electrolytically on the surface.
