Aluminum electrolytic capacitors are electrical components that utilize a chemical property of aluminum on one of its electrodes. These capacitors provide a wide array of application fields due to their ability to maintain a significantly high value of capacitance in a relatively small volume, and their working principle is simple and well studied. The UKA1E221MPD is one such capacitor, which takes on a particularly robust construction method, perfect for demanding applications.

Application Field

The UKA1E221MPD is a general-purpose Axial capacitor, made of aluminum electrolytic capacitors. It comes in a compact package of mechanical dimension 6.3x11.2mm; its radial lead structure gives it an especially wide application field. This capacitor is best used in consumer electronics, particularly in automotive equipment such as car stereos, climate control systems, and others. Additionally, it can be useful in other low-voltage, high-capacitance applications such as in computers and medical devices as well.

The some other application fields of this capacitor include amplifier circuits, LED driver circuits, switching power supplies, and other circuits requiring a medium current range. Being an axial capacitor, its installation is also easy and does not require a great amount of space. Its wide temperature range from -55 to +105 degrees Celsius also makes it a good choice for high temperature applications. Additionally, it also has an excellent ripple current-life performance, which adds to its usability in so many applications.

Working Principle

The working principle of aluminum electrolytic capacitors is very simple yet effective. Essentially, it involves two thin aluminum foils with a thin paper-like separator between them, placed in an electrolyte solution. When the electrolyte is applied to the capacitor, the two foil terminals become the anode and the cathode electrodes of the capacitor, respectively.

This capacitor works through an electrochemical reaction, where an electrical current is applied to the anode, resulting in a thin layer of aluminum oxide being formed between the separator and the anode. This oxide layer works as a dielectric, and it allows the capacitor to store electrical energy. The capacitance of the capacitor therefore depends on the area of the anode, the thickness of the oxide layer, the voltage applied, and the dielectric constant of the electrolytic solution.

The UKA1E221MPD is an especially reliable and durable capacitor, due to its low impedance and high temperature resistance. This is enabled by MnO2 as the internal electrode material, which is why these capacitors are said to have long life. It also has a high ripple current-life performance, increasing its lifespan even more. All of this makes it a perfect choice for a variety of demanding applications.

Conclusion

In conclusion, the UKA1E221MPD capacitor is an especially suited component for high temperature, high current, and high capacitance applications. It takes on a robust construction method, featuring MnO2 as its internal electrode material, giving it low impedance, high temperature resistance, and a high ripple current-life performance. This gives it an especially wide application field suitable for use in automotive equipment, computers, medical devices, and so on. The working principle of this capacitor is simple yet effective, making it extremely reliable and durable.
