Aluminum Electrolytic Capacitors are widely used due to their relatively low cost paired with high capacitance and volumetric efficiency compared to other types. UPM1E221MPD6 belongs to aluminum electrolytic capacitor and its application field and working principle is described in this article.

UPM1E221MPD6 is a 105°C snap-in aluminum electrolytic capacitor. The rated voltage of the capacitor is 16V and its capacitance is 220µF, which is usually used in filters, rectifying, coupling and bypass circuits. UPM1E221MPD6 snap-in aluminum electrolytic capacitor has a variety of features, such as snap-in mounting, high ripple current capability, long life and many others.

The application field of UPM1E221MPD6 aluminum electrolytic capacitors are largely dependent on their rated voltage and capacitance. The rated voltage of 16V makes it suitable for a variety of circuits with low voltage, such as DC-DC converters, audio power amplifiers and other electronic circuits. The 220µF capacitance makes it suitable for filtering, rectifying and bypass circuits. It is also used in some battery-powered applications, such as battery backup circuits and motor control systems.

UPM1E221MPD6 aluminum electrolytic capacitor operates as follows. When voltage is applied, electric field lines appear in the dielectric. The electric field lines induce molecular polarization of the dielectric, resulting in a positive and negative distribution of charge carriers across the dielectric. This distribution of charge carriers generates an electric field of its own, and the combination of the electric field generated by the charge carriers and the applied voltage results in an electric field of a larger magnitude than either applied voltage or charge carrier field. This larger electric field breaks down the molecule barrier of the dielectric, allowing electrons to flow through the dielectric. As current passes through the dielectric, a capacitance is formed, allowing for the storage of energy within the capacitor. When the electric field lines between the plates of the capacitor are removed, the dielectric gets polarized again and capacitance is reduced, releasing energy stored within the capacitor.

The main components of UPM1E221MPD6 aluminum electrolytic capacitor include the aluminum capacitor can, the aluminum capacitor foil, the silver plating layer, and the dielectric. The aluminum capacitor can is made from electrolytic aluminum with a black anodized layer on it. This serves as the enclosure of the capacitor and provides protection for the internal components. The aluminum capacitor foils, which serve as the anode and cathode of the capacitor, are made from etched electrolytic aluminum and are silver-plated. The silver plate layer provides an electric contact between the capacitor can and foil for the transfer of current. The dielectric is a layer of material between the anode and cathode that prevents the two components from coming into contact and shorting the capacitor. The dielectric is made of organic substances such as polypropylene or polyester.

UPM1E221MPD6 aluminum electrolytic capacitor has many advantages over other types. It is lightweight, has low resistance, and offers a wide range of capacitance values. Additionally, the caps are mechanically durable due to the aluminum material construction and the capacitors have good self-healing properties, allowing them to be used safely in even high temperature and vibration environments.

In conclusion, UPM1E221MPD6 aluminum electrolytic capacitor has numerous application fields due to its various features. Its low price, high capacitance value, and wide range of rated voltages make the capacitor an ideal choice for various circuits. Additionally, its working principle allows it to store energy and release it when needed. Hence, UPM1E221MPD6 aluminum electrolytic capacitor is a suitable choice for many applications.
