Aluminum electrolytic capacitors, or ‘Al-Elec’ for short, are the most common type of capacitor used in electronic circuits today. Their main advantage is their high capacitance to small size ratio, giving them the ability to store large amounts of charge in a relatively small package. The capacitance of aluminum electrolytic capacitors is measured in farads (abbreviated to F). The type of aluminum electrolytic capacitor under consideration here is coded 100PX47MEFC8X11.5, which is characterized by a tantalum dielectric, low ESR and long life cycle.

The 100PX47MEFC8X11.5 aluminum electrolytic capacitor can be used for a wide range of applications including power supplies, dc-dc converters, electronic ballasts, inverters, transformers and motor drivers. Its operating temperature varies from -25 to +85°C, making it suitable for most electrical and electronics applications. Its rated voltage is 63V DC, and it has a capacitance of 47μF. The ESR (equivalent series resistance) of the 100PX47MEFC8X11.5 aluminum electrolytic capacitor is low, meaning it can support large current levels without overheating.

The working principle of an aluminum electrolytic capacitor is based on the principle of electrochemical cells. It consists of an aluminum foil, electrolyte solution and a separator material. The aluminum foil act as the plate of a cell, while the electrolyte solution produces the electric current. When a potential difference exists between the two plates of the capacitor, the electrolyte ions move from one plate to the other, creating a chemical reaction that generates a current. This current passes through the electrolyte solution and creates an opposite chemical reaction, thus generating a charge.

The separator material prevents the two plates from making direct contact. The electric current circulating inside the aluminum electrolytic capacitor causes the ions of the electrolyte to chemically react with the aluminum foil. This chemical reaction is responsible for forming an insulating layer of oxide on the aluminum. This thicker layer of oxide which builds up over time, reduces the effective capacitance of the capacitor.

In order to prevent this build-up of oxide, aluminum electrolytic capacitors are designed with an anode that is normally slightly larger than the cathode, thus allowing a certain amount of space for the oxide layer to form while still maintaining the desirable capacitance. The use of a self-healing electrolytic capacitor can help extend the life of the capacitor, as the oxide layer formed on the anode can be periodically removed, thus restoring the original level of capacitance.

The 100PX47MEFC8X11.5 aluminum electrolytic capacitor is a reliable device designed for a range of electrical and electronic applications. Its low ESR and long lifecycle make it an excellent choice for applications requiring high current levels, while its measured capacitance of 47μF ensures that it can store large amounts of charge in a relatively small package.
