Aluminum electrolytic capacitors, also known as ‘electrolytic capacitors’ or simply ‘electrolytics’, are electrical components used in a wide variety of applications. They are formed by electrolytically depositing an aluminum anode and a dielectric oxide film on a rolled aluminum foil. An aluminum electrolytic capacitor is distinguished from other types of capacitors by its large capacitance value for a given volume or footprint. This makes aluminum electrolytic capacitors ideal for use in applications where a very high capacitance is needed in a small space.

The main application of aluminum electrolytic capacitors is for use in power conversions or power filtering. They are widely used in the power supplies of computer systems, electronic audio equipment, household appliances, and industrial control systems. They help improve the performance of the power supply by helping to reduce the ripple, reduce the inrush current, and provide over-voltage protection. Aluminum electrolytic capacitors are also used in signal processing as they are ideal for high frequency switching and other power conditioning applications.

In addition to their use in power conversion and filtering, aluminum electrolytic capacitors are also used in applications such as timing circuits, voltage suppression, signal coupling, and energy storage. They are an important component to reduce the EMI caused by the switching of the power IC. They are also used for transient suppression or snubber circuits which absorb energy in the form of electrical or magnetic fields. In fact, aluminum electrolytic capacitors are used in almost any application that requires a high capacitance value.

UVZ2A3R3MDD is an Aluminum Electrolytic Capacitor which is a product of Chun Ying Co Ltd, one of the largest capacitor manufacturers in Taiwan. It is a vertical leaded surface mount type capacitor, with an enlarged side tab for increased mechanical stability in high vibration applications. It has a non-inductive design with a screw-down type terminal and a basic rated voltage of 63 V DC. It is RoHS compliant and AEC-Q200 qualified.

UVZ2A3R3MDD aluminum electrolytic capacitors offer a wide range of working temperatures from -40°C to +85°C. Their short and long-term ripple current capabilities make them suitable for use in high-frequency, high-reliability applications. Their self-healing properties are also beneficial in applications such as power supplies and audio equipment, which require high-accuracy and fast response.

In terms of working principle, aluminum electrolytic capacitors make use of electrolytic and oxide films to store electrical energy. The anode is typically made of aluminum foil covered with a thin layer of metal oxide. When a voltage is applied across the terminals of the capacitor, ions are attracted to the anode to form the electric double-layer. The barrier between the two layers forms a dielectric medium which stores the energy. The capacitance value is determined by the anode material, the oxide thickness, and the area of the anode.

In short, UVZ2A3R3MDD aluminum electrolytic capacitors are an ideal choice for many applications due to their high capacitance value, long service life, and ability to withstand high temperatures. They are suitable for high-performance and high-frequency applications and are RoHS compliant. With a wide range of working temperatures, these capacitors are also able to offer superior performance.
