Aluminum electrolytic capacitors, often shortened to aluminum electrolytics, are capacitors whose anode electrode is made of aluminum foil with an etched surface. An electrolytic solution, usually containing an organic solvent, is used as the dielectric. A second foil, the cathode, is in contact with the electrolyte.The KY35VB222M18X25LL belongs to this type of capacitors.

The main features of the KY35VB222M18X25LL aluminum electrolytic capacitors are a capacitance of 2200uF and voltage rated at 35V. They come in an E style, 25mm long, 18mm diameter packages, and have a temperature range of -40°C to +85°C.These particular capacitors offer excellent low-ESR performance, and their characteristics make them particularly suitable for high-frequency applications such as switching power supplies, DC/DC converters, inverters, and converters. They can also provide excellent stability over time and temperature, ideal for audio and telecommunication circuits.

The KY35VB222M18X25LL aluminum electrolytic capacitor is built using polarized electrolyte technology. There are two layers of electrodes; the anode is made of aluminum foil with an etched surface, and the cathode is made of aluminum oxide film. An electrolytic solution is used as the dielectric in between the layers.

The work principle of a KY35VB222M18X25LL aluminum electrolytic capacitor is based on the accumulation of charge onto the aluminum oxide layer when a voltage higher than the rated voltage is applied to the capacitor. This charge attracts the positive charge of the electrolyte solution, which in turn absorbs further charge from the adjacent aluminum anode. This forms an electric double layer between two electrodes, separating negative ions from positive. This double-layer, thanks to the combination of the electrolyte and the oxide layer, works as a dielectric, increasing the efficiency of the capacitor.

In conclusion, the KY35VB222M18X25LL aluminum electrolytic capacitor is a polarized capacitor that is mainly used for applications such as switching power supplies, DC/DC converters, inverters, and converters, as well as for audio and telecommunication circuits. It features a capacitance of 2200uF and voltage rated at 35V, making it particularly suitable for high-frequency applications. It is built using polarized electrolyte technology, making use of an electric double-layer to separate negative ions from positive, thus increasing the efficiency of the capacitor.
