Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electronic component used for storing electric charge in the form of an electrostatic field. It is made of two aluminum foils which are separated by a thin anodic oxide layer. The electrolyte between them acts as a dielectric material which stores energy in electrostatic form. Typical capacitances can range from a few picofarads to hundreds of millifarads.The SMQ350VS681M35X35T2 is a type of aluminum electrolytic capacitor. It is an aluminum electrolytic capacitor with a capacitance of 350V. The maximum working voltage of this capacitor is 681V and it has a high temperature rating of up to 175°C. The SMQ350VS681M35X35T2 has an axial lead configuration which makes it suitable for surface mounting.The typical application fields of the SMQ350VS681M35X35T2 are for filtering, buffering and high voltage applications in a wide range of electronic circuits. It can be used in a variety of systems such as power supplies, current limiting circuits, data acquisition systems, communication systems, and motor drive systems. This type of capacitor can also be used to provide power storage in applications that require a high energy density and fast response time, such as power switches, surge protectors, and pulse generators.The working principle of an aluminum electrolytic capacitor is based on the double layer structure of the oxide film. When a voltage is applied to the electrodes of the capacitor, a potential difference is created across the oxide layer. This potential difference activates electrochemical reactions which generate surface charges on the aluminum foil that acts as a dielectric material. The capacitance of the capacitor is determined by the thickness of the oxide layer which, in turn, is dependent on the amount of voltage applied across the electrodes. The capacitance of these types of capacitors decreases if the temperature rises due to the decrease in the thickness of the oxide layer.The SMQ350VS681M35X35T2 is a stable and reliable aluminum electrolytic capacitor. Its axial lead configuration makes it ideal for use in a wide range of high voltage and current applications. It has an impressive voltage rating and high temperature rating for superior performance in even the most demanding applications. Its highly stable capacitance is ideal for filtering, buffering, and other power applications.
