Aluminum electrolytic capacitors are widely used in electronics, electrical and other applications. The EEE-TG2A470Q is an example of an aluminum electrolytic capacitor. Its properties and applications are discussed in this article.

An aluminum electrolytic capacitor is composed of an aluminum oxide (Al2O3) film as the di-electric, which is formed on the surface of an aluminum foil. An electrolyte is present in the capacitor, which serves as a medium for electrons and ions. This combination allows the capacitor to store energy when q voltage is applied. The aluminum oxide film acts as a barrier to prevent the electrons from passing through the capacitor, thus increasing the capacitance.

The EEE-TG2A470Q is a product of AEC. It is rated at 470uF, 2.5V with a 105°C operating temperature. It is an axial type aluminum electrolytic capacitor with an extended temperature range. The capacitor is RoHS compliant and halogen free.

The EEE-TG2A470Q can be used in several types of applications such as power supplies, converter circuits, high-frequency switch mode applications, high-temperature, high-current and high-voltage circuits. It is also suitable for filtering, buffering and bypassing applications. This capacitor is particularly suitable for components that are exposed to conditions beyond the application limits of normal electrolytic capacitors.

The EEE-TG2A470Q offers several advantages such as higher temperature ratings, longer life, greater stability and greater surge current capacity. It is also resistant to thermal and electrical ageing and can be used over a wide range of temperatures. Furthermore, the EEE-TG2A470Q has a low equivalent series resistance (ESR) and low insulation resistance, which help to reduce power losses in the circuit.

The working principle of the EEE-TG2A470Q is based on the formation of a semi-permeable membrane on the surface of the aluminum foil. This membrane is formed by the reaction of anodic oxidation of the aluminum with the electrolyte solution. This membrane is composed of nanoparticles of Al2O3, which form an almost impermeable barrier for electrons, thus forming a dielectric barrier. When an electric field is applied, electrons are attracted to the cathode and repulsed from the anode. This causes a charge to accumulate on one side of the capacitor, thus creating a capacitance. The capacitance of the capacitor is proportional to the applied voltage.

In conclusion, the EEE-TG2A470Q is a type of aluminum electrolytic capacitor which is specifically designed to operate in high temperature and high current conditions. It has an extended temperature range, a high capacitance and a low ESR. It can be used in a wide variety of applications such as power supplies, converters, high-frequency switch mode applications and other applications which require longer life and greater stability. This capacitor is also highly resistant to thermal and electrical ageing.
