Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in a variety of applications for their high volumetric efficiency, wide temperature range, and low equivalent series resistance (ESR). Based on the type of electrolyte used, they are also classified as wet or polar electrolytic capacitors. The most common type of wet electrolytic capacitor in power applications is the ECE-P2WA152HA series.

ECE-P2WA152HA Application Field

The ECE-P2WA152HA series of wet aluminum electrolytic capacitors is designed specifically for use in powersupply filter circuits, high-side energy storage devices, DC/DC converters, motor starters, PFC circuits, IGBT/MOSFET gate drive circuits, and other similar applications. The series is characterized by high rated capacitance, high ripple current capability, and is hermetically sealed to ensure reliable operation in adverse environmental conditions.

ECE-P2WA152HA Working Principle

The ECE-P2WA152HA series utilizes wet electrolytic technology to achieve its high volumetric efficiency and low ESR. A liquid electrolyte is stored within its sealed metal case and is used to plate out a thin layer of aluminum oxide on the anode. The anode and metal case form the dielectric of the capacitor, and the electrolyte acts as the cathode. This arrangement allows for the creation of an electric field, which stores electrical energy.This electric field causes a change in surface potential on the anode and cathode, and this creates a charge separation. This charge separation creates an electric potential around the capacitor, allowing it to store energy. When a voltage is applied across the capacitor, the electric field that was previously established is reversed and capacitance is removed from the system.The aluminum electrolytic capacitor also has an extremely high ripple current capability, allowing it to operate in high-frequency switching power supply circuits. Due to its low ESR values, it is also able to function as an output filter in severely distorted environments.

Conclusion

The ECE-P2WA152HA series of aluminum electrolytic capacitors is designed for use in high-power applications such as industrial, automotive, and aerospace applications. Its high volumetric efficiency and low ESR make it an optimal choice for power supply filter circuits as well as other high-side energy storage devices. Its ability to operate in high-frequency switching power supply circuits due to its high ripple current capability and its low ESR values make it a great choice for output filter applications.
