Aluminum electrolytic capacitors are capacitors with a dielectric oxide film mainly composed of aluminum oxide and a few traces of anions. It has the advantages of large capacity, small volume, low item value and good self-stability, which is widely used in power supply, electronic information, communication and other fields.

The UCA2G6R8MPD application field and working principle can be classified under the Aluminum Electrolytic Capacitors. This particular capacitor is a miniature long life aluminum capacitors which are ideal for high ripple current applications. It has a small, low-profile design for board space savings, multiple capacitance and voltage ranges, and long shelf life.

The UCA2G6R8MPD aluminum electrolytic capacitor has wide operating temperature range from -40℃ to +105℃, with voltage ratings of 6. 3V and 16V. It has ripple current of 265mA, capacitance of 2198µF and life expectancy of up to 5000 hours at +105℃. It also offers low impedance capability for high frequency applications.

The working principle of aluminum electrolytic capacitors is that the aluminum foil acts as an anode, is etched on its surface to form a high surface area, and then a layer of aluminum oxide is formed on the surface. An electrolyte is placed between the anode and the electrolyte and the electrolyte provides ions to be oxidized and reduced in the anode and electrolyte, forming an electric double layer capacitor effect, so that a capacitance is formed. This capacitance value is related to the surface area of ​​the anode, the specific area of ​​the anode, the thickness of the oxide layer, the dielectric loss factor of the oxide, and the concentration of the electrolyte.

The advantage of aluminum electrolytic capacitor is that it can produce extra large capacitance in a very small volume. The maximum capacitance and temperature coefficient range of this capacitance are much larger than other types of capacitors, and the performance is relatively stable. It can be used in various harsh environments, and has a long life, up to 10000 hours.

In conclusion, the UCA2G6R8MPD application field and working principle can be classified under the Aluminum Electrolytic Capacitors which has wide operating temperature range, large capacitance, and long life expectancy. Its working principle is that a capacitance is formed as a result of an electric double layer capacitor effect between the anode, electrical and electrolyte. As an advantage, aluminum electrolytic capacitors can produce extra large capacitance in a very small volume, which is suitable for high ripple current applications.
