Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are components widely used in modern electronics. They are constructed with two aluminumfoil layers separated by a layer of porous paper soaked in an electrolyte solution. The configuration of the layers results in an increased surface area, thus increasing the capacitor’s overall capacitance.The model EKMH630VSN153MA63W is an aluminum electrolytic capacitor from Nichicon. It has a maximum rated voltage of 630V and a capacitance of 153uF. Its aluminum-etched terminal has a current carrying capacity of 3.2A and its operating temperature range is between -40℃ and +85℃.

Application Field

The EKMH630VSN153MA63W is commonly used for main circuit, auxiliary circuit, and output circuit in power supplies, as well as automotive and lighting applications. It is typically used in power amplifiers, and other power equipment that require a large capacitance of up to maximum 1000uF.Due to its large capacitance and maximum rated voltage, the EKMH630VSN153MA63W is recommended for applications where a large current flows, as this capacitor is able to effectively reduce current noise.The capacitor is also well-suited for applications that require vibration resistance, as its sealed construction greatly reduces noise caused by vibration. It even works under harsh environmental conditions, as its sealed construction prevents it from being affected by temperature and humidity.

Working Principle

Aluminum electrolytic capacitors function by storing electrical charge in an electrolyte solution between two electrodes. The current flow between the electrodes is regulated by the resistance of the electrolyte solution. As the charge builds up at the electrodes, it forms an electric field between them. This electric field is regulated by the thickness of the electrolyte solution.The EKMH630VSN153MA63W has two aluminum layers: the anode and the cathode. When current flows between these two layers, a voltage potential builds up across the electrolyte layer, which results in a charge differential that can store electrical charge.The capacitance of the EKMH630VSN153MA63W is determined by the size of the anode and cathode layers, and the amount of current that can flow between them. The thickness of the electrolyte layer also has an effect on the capacitance, as it determines the amount of resistance that will be created when a voltage potential is applied across it.In summary, the EKMH630VSN153MA63W is an aluminum electrolytic capacitor that is widely used in modern electronics. It is able to provide a large capacitance of up to 1000uF, a maximum rated voltage of 630V, and a maximum current carrying capacity of 3.2A. It is suitable for applications that require vibration resistance and its sealed construction makes it suitable for harsh environmental conditions.
