Aluminum Electrolytic Capacitors are widely used in the power supply frequency control circuit of Industrial Control System, Automation System, UPS System, and Frequency Conversion System, as well as in the motor soft-starting circuit and the ripple prevention circuit. And the ALS70A183QW350 is an aluminum electrolytic capacitor that is used for pulse energy storage and decoupling filter, etc. It has a capacity of 7 uF and a maximum rated working voltage of 350V.

The basic principle of aluminum electrolytic capacitors is that liquid ionic electrolyte will conduct electric current and charge or discharge the capacitor plates of polarities, allowing oxide layer to form on aluminum plate, which is the connected terminal of capacitor. When discharging, the ionic electrolyte will pass through this oxide layer, and so cross charge can be produced. When charging, the electrolyte will travel on the surface of the oxide layer, and the charge of positive and negative plates can be transferred. Due to the existence of oxide layer with high electrical resistance, when the capacitor is left in a state of charge or no current pass through, the electrical leakage will be reduced and the electric capacity can also be maintained stable.

The ALS70A183QW350 aluminum electrolytic capacitor is usually made of a cylindrical case which can guarantee the capacitor core is securely sealed. The case is usually made of materials of high insulation, such as ABS or PET, with its top clear or printed with the product information, and can effectively prevent sudden rise of internal temperature and ignition. Additionally, this aluminum electrolytic capacitor is epoxy sealed with two solder-pad terminals in order to reduce the risk of electric leakage. The terminals provide convenient connections for other electrical elements.

In terms of application field, the ALS70A183QW350 aluminum electrolytic capacitor is widely used in UPS systems, Automation systems, Industrial control systems, Frequency conversion systems, motor soft-start circuits, and ripple prevention circuits. In Automation systems, it is used in controlling the pulse power for the motor drive circuit, and to backup the main capacitor for the power supply. As for the Industrial control system, it is applied in controlling the pulse energy storage for a given pulse motor drive, to reduce the noise of the signal lines. And in Frequency conversion systems, it can be used for the backup of the main capacitor of the system, in order to maintain the system at a certain voltage level.

In conclusion, the ALS70A183QW350 aluminum electrolytic capacitor is highly stable and reliable, and has broad application options. With the simple but yet effective working principle, it can determine the electrical capacity of a capacitor and reduce the risk of possible electric leakage. Therefore, many circuit designers are often relying on this aluminum electrolytic capacitor for their electric projects.
