Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are widely used in numerous electronic applications. The ALS70A622MF350 capacitor is an example of an AEC and is used in various fields, such as power supply and filtering. It has a rated voltage of 70V and a capacitance of 6.2μF The maximum working temperature that can be handled by this capacitor is 85℃. This capacitor is specially designed for vertical PCB boards with high efficiency, fast response time, and a high temperature coefficient of capacitance.AECs have a unique construction compared to other types of capacitors. An AEC is composed of two parts: an aluminum anode and a cathode-controlled ‘wet’ electrolyte. The anode and electrolyte are separated by insulating paper or plastic, and the components are packaged in either an axial or radial configuration, depending on the application. The electrolyte is usually composed of various acids, such as sulfuric or hydrofluoric, and a special type of insulator. The combination of the electrolyte and anode surface area dictates the capacitance value of the capacitor.The ALS70A622MF350 capacitor’s anode is formed of aluminum oxide which acts as dielectric. The electrolyte is contained between the anode and cathode layers, and completes the AEC circuit. When the capacitor is charged, the electric field generated by the voltage increases on the surface of the aluminum oxide. This allows the electric field to penetrate the oxide layers and then the electrolyte which further increases the voltage on the positive layer. This causes a charge polarization in the electrolyte and creates the capacitor’s ability to store energy.This process is the foundation of the working principle of an AEC.There are a variety of fields in which the ALS70A622MF350 can be used. It is predominantly used as a power filter capacitor, as it is able to reduce ripple in the power supply. The capacitor also offers a high temperature coefficient of capacitance, meaning its capacitance remains stable with the varying temperature. In addition, the ALS70A622MF350 is employed in numerous other scenarios such as a bypass capacitor for audio (high-frequency) applications and as a bulk-head capacitor, which is used in the audio signal path and as an input filter.The unique structure and qualities of the ALS70A622MF350 make it an ideal choice for numerous electronic applications. It offers a low ESR, a high temperature coefficient of capacitance, and a wide temperature range. These benefits make the ALS70A622MF350 a versatile and reliable AEC.It is important to note that AECs require special care when soldering. As the electrolyte is sensitive to heat, it is essential that the capacitor is not exposed to much heat when soldering. This will ensure the capacitor is not damaged during the soldering process.In conclusion, the ALS70A622MF350 is an efficient, reliable and widely used AEC. Its unique construction and quality characteristics make it an ideal choice for a variety of applications. As such, it is an important part of any electronic design process.
