Aluminum electrolytic capacitors are widely used in high-frequency switching power supplies, DC/DC converters, computers, telecommunications, instrumentation, consumer electronics and other fields due to their high capacity, high voltage, low ESR and long life. CGS552U016R2C, a type under this category, is a miniaturized, low-leakage, gel-filled aluminum electrolytic capacitor with a non-solid electrolyte. It has a temperature range of -55C to +105C, a rated voltage of 25V, a maximum voltage of 50V, a capacitance of 470uF, and a tolerable ripple current of 800mA.

CGS552U016R2C works through a series of electrochemical reaction to store electrical energy and release it back when needed. Its internal construction consists of two aluminum foils, rolled together with a thin sheet of insulating paper called the separator between them. Each of these foils is then coated with an electrically active layer, an oxide layer on the anode foil and manganese dioxide on the cathode foil. The surface area of the anode and cathode foils is greatly increased by etching them with microscopic tunnels, resulting in their increased capacitance. This is compared to the flat sheets used in plain foil-paper capacitors.

The electrolyte gel is then spread between the foils and absorbs any excess fluid that surrounds them. This prevents it from migrating and increasing the resistance of the capacitor, while allowing it to withstand higher temperatures than that of the ordinary liquid electrolyte capacitors. As the walls of the tunnels are so thin, no parts can move freely within them, so they can reduce the amount of mechanical noise created by the movement of components. It also reduces the total amount of leakage current generated.

The CGS552U016R2C is generally used in the power supplies of audio amplifiers, computers, industrial equipment, electric vehicles, medical equipment, and DVD players. It can also be used in rectifier circuits, DC-DC converters, switching regulator circuits, and transient voltage suppressors. Due to its high capacitance, low ESR, and long life, it can also be used for broad frequency range filter applications, such as low pass filters and mass storage unit drivers.

In conclusion, the CGS552U016R2C is a miniaturized, low-leakage, gel-filled aluminum electrolytic capacitor with a non-solid electrolyte. It is suitable for a wide range of power supplies, rectifier circuits, switching regulator circuits, and transient voltage suppressors. With its high capacitance, low ESR, and long life, it makes for ideal low pass filters, mass storage unit drivers and other general purpose capacitive applications.
