Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors are polarized capacitors having very large capacitance values in single component. They feature substantial energy density due to their very high capacitance compared to other types of capacitors, which makes them exceptionally well-suited to large energy storage applications.

The EET-EC2D122JA is a low-ESR (equivalent series resistance) surface mount aluminum electrolytic capacitor specifically designed for high ripple current applications in automotive electronics. This includes applications such as power converter and motor-control circuits.

In order to understand the field of application for the EET-EC2D122JA, it is important to understand the basic working principles of aluminum electrolytic capacitors.

Working Principle

An aluminum electrolytic capacitor consists of an anode and a cathode, separated by a thin insulating oxide layer. This layer of oxide is formed when aluminum and an electrolyte react. The anode and the electrolyte are connected to the power supply, and current passes through them to the oxide layer. This creates a voltage difference between the two terminals, which generates an electric field.

However, the electrolyte is not able to pass directly through the thin oxide layer, so the electric field is created across the entire oxide layer. The electric field causes electrons to be attracted to the metal within the oxide layer, which increases the capacitance of the device. The higher the capacitance, the more energy the capacitor can store as charge.

The EET-EC2D122JA uses this principle to create a high-capacity, high-temperature-resistant capacitor with high reliability. The low ESR and high ripple current ratings make it ideal for automotive applications.

Application

Due to its high capacitance and low ESR, the EET-EC2D122JA is perfect for power converter and motor-control circuits found in automotive applications. With its high temperature endurance, it is well suited for high temperature automotive power supplies and is suitable for high-temperature under-hood applications.

The EET-EC2D122JA is also suitable for all kinds of brushed and brushless DC motor and power supply applications, such as e-bikes, cars, boats, motorcycles, ATVs, and other mobile applications. In addition, it is also ideal for high reliability pulse power supplies, LED power supplies and factory automation machinery.

Due to its high capacity and low ESR, the EET-EC2D122JA is the perfect solution for high-temperature applications, where high reliability and high power density are desired. The company behind this capacitor also offers a variety of other capacitor products that have similar features and can be used in any high current applications.
