Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also referred to as a polarized aluminum electrolytic capacitor, is an electrical component used to store electrical energy in an electric field. It is a type of capacitor with an anode made out of aluminum foil and a dielectric of semi-liquid substance. The cathode of the capacitor is built of a layer of aluminum oxide formed on the aluminum foil.

The capacitor 516D107M050MM6AE3 is an example of an aluminum electrolytic capacitor. This particular model has a capacitance of 107mF, a voltage rating of 50VDC, and a temperature range of -40C to +105C. It has a maximum leakage current of 3.0uA, making it suitable for use in high-temperature and high-power applications.

Application Field

Aluminum electrolytic capacitors are used in a variety of applications. Some notable examples include automotive, consumer electronics, and industrial use. In these applications, the capacitor is used to store and quickly release energy. This can be done for a variety of purposes such as filtering power, controlling frequency, peak current suppression, and providing surge current.

Aluminum electrolytic capacitors are particularly well-suited for high-temperature applications as their dielectric is alkaline. This increases their temperature range and allows them to be used in high-temperature applications, such as car air conditioners and motor controllers.

Working Principle

Aluminum electrolytic capacitors function on the principle of an electric double layer. This is created when electric current is applied to two surfaces (anode and cathode) which are separated by a dielectric medium. The electric current creates an electric field between the two surfaces, causing one surface to become negatively charged and the other surface to become positively charged.

When a potential difference is applied to the capacitor, an electric field is created between the anode and cathode. This causes electrons to move from the anode to the cathode, creating a current. This current gradually decreases as the potential difference decreases.

The capacitance of an aluminum electrolytic capacitor is determined by its size and by the thickness of the dielectric. The capacitance increases as the size and the thickness of the dielectric increase. The capacitance also increases as the voltage across the capacitor increases.

Conclusion

Aluminum electrolytic capacitors are essential components in a wide variety of electronic applications. They are characterized by their high capacitance, low equivalent series resistance (ESR), and long lifetime. The 516D107M050MM6AE3 aluminum electrolytic capacitor is an example of such component and can be used in automotive, consumer electronics, and industrial applications.
