Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as electrolytic capacitors, are types of electrochemical capacitors with a dielectric composed of an oxidized aluminum foil with an etched surface. They are the most widely used type of capacitor, and come in a variety of configurations for a range of applications, including AFK108M25H32VT-F.

AFK108M25H32VT-F Characteristic

The AFK108M25H32VT-F aluminum electrolytic capacitors from Sinox are designed to meet industry standards for precision and compatibility. This product features a voltage rating of 16 VDC, capacitance of 108 μF, lifetime of 2000 hours, and an operating temperature range of 30-85 °C. It also features radial leads, radial orientation, and meets RoHS requirements.

Application Field of AFK108M25H32VT-F

The AFK108M25H32VT-F is primarily used in power supplies, featuring high power density. It is also used in a variety of DC-DC converters, automotive choke/ignition circuits, LED drivers, and power supplies for medical equipment. In addition to power supplies, the AFK108M25H32VT-F is also used in antenna tuned circuits, voltage regulation, precision applications including clock and timing circuit, battery elimination circuits, and more.

Working Principle

The AFK108M25H32VT-F aluminum electrolytic capacitors are constructed with an anode and a cathode. The anode consists of an aluminum foil with an etch pattern, while the cathode is constructed with a thin layer of oxide film which acts as the dielectric.When current is applied, the oxide layer is polarized, creating an electric field across the dielectric. This electric field then stores energy, much like an open circuit capacitor. The amount of energy stored is related to a capacitor’s capacitance.The capacity of an aluminum electrolytic capacitor is determined by its design parameters, including anode/cathode length-to-diameter ratios and the area of the anode. The capacitance can range from 0.47 μF to 3,300 μF depending on the design parameters.

Advantages

The main advantages of aluminum electrolytic capacitors over other types of capacitors are their high capacitance, long lifetimes, and low cost. They are also smaller in size, making them ideal for a number of applications.Additionally, aluminum electrolytic capacitors have a high ripple current capacity as well as high insulation resistance due to the high dielectric strength of the oxide layer.

Disadvantages

The primary disadvantage of aluminum electrolytic capacitors is their relatively short lifetime due to the corrosive nature of aluminum oxide and the ever-present risk of shorting. In addition, electrolytic capacitors are also prone to performance degradation due to dielectric loss, leakage current, and other factors. These factors can be mitigated with proper selection of components and good design.

Conclusion

The AFK108M25H32VT-F aluminum electrolytic capacitors are widely used in a variety of applications due to their compact size, high capacitance, low cost, and long lifetime. While their performance is not ideal in all applications due to their relatively short lifetime, they can still be trusted for many power supply and precision application needs.
