Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, commonly known as electrolytic capacitors, are polarized capacitors consisting of an anode made up on an aluminum foil with an etched surface and a solid electrolyte as a cathode. A double layer of oxide forms on the surface of the aluminum foil as a dielectric. They are the most commonly used capacitors in electronic circuits for filtering, timing, and signal processing.

LPX271M350H1P3 are aluminum electrolytic capacitors that are designed with an organic polymer cathode. The organic dielectric is designed to provide enhanced properties and high reliability. The LPX271M350H1P3\'s features are excellent capacitance retention and High Ripple Current capability. Its unique structure eliminates wet electrolyte leakage and results in a highly reliable capacitor. These capacitors are suitable for use in home theater systems, desktop PCs, and servers.

Working Principle

The working principle of aluminum electrolytic capacitors is based on Faraday laws. In an electrolytic capacitor, the electrodes are formed by a thin oxide film formed on the anode and a bipolar electrolyte that acts as the cathode. The capacitor can be polarized, acting as a diode. The oxide film acts as the dielectric layer which separates the two electrodes and allows an electrical charge to be stored between them.

The two most important characteristics of an electrolytic capacitor are its capacitance and its equivalent series resistance (ESR). The capacitance is determined by the size and geometry of the capacitor and its dielectric material. This influences the capacitance of the capacitor, and is often the main parameter considered by designers. The ESR, on the other hand, is determined by the properties of the electrolyte used in the construction of the capacitor and has no direct influence on the capacitance.

The electrolytic capacitor also has a limited working temperature range. Devices with a minimum rated temperature usually have higher leakage currents than those with a higher minimum rated temperature. As a result, it is important to consider the temperature range of the capacitor before selecting it for an application.
