Aluminum electrolytic capacitors, one of the most widely used passive components in electronics, are composed of two electrodes filled with electrolytic solutions and sealed in an aluminum shell. The EET-UQ2W331DA is a type of aluminum electrolytic capacitor particularly designed for use as a dc-link filter capacitor in inverters of photovoltaic systems. It provides many advantages, such as high capacitance, low equivalent series resistance values and large ripple currents.

The EET-UQ2W331DA is mainly applied to PV power systems as a filter for the DC-link circuit, specifically when PV-systems are applied for residential or commercial power generation. It is also suitable for various types of inverters used in industrial fields and for hybrid power systems such as those in automobiles and ships. The high temperature-resistant grade allows its application in extreme temperature conditions, which is an important criterion for many PV-systems.

The working principle of the EET-UQ2W331DA is based on an electrochemical reaction between an electrolyte and two electrodes. These electrodes are made from aluminum, and the electrolyte is an oxide solution which creates an electric double layer when it comes in contact with the aluminum electrode. This electric double layer forms the capacitance of the aluminum electrolytic capacitor and allows it to store electrical energy, much like a standard capacitor does.

The voltage rating of the EET-UQ2W331DA is 400V, which allows its use in PV-systems that are designed to operate at a higher voltage level. It also provides an excellent ripple current handling capacity at high temperatures, up to 85°C, which is a major advantage for many applications in photovoltaic systems. The EET-UQ2W331DA also has very low leakage currents, making it suitable for long-term operation in PV systems.

In addition, the EET-UQ2W331DA has a wide operating temperature range of -55 to +125°C as well as a very low equivalent series resistance (ESR). The ESR value determines the effectiveness of the capacitor in efficiently controlling ripple currents, which is a crucial parameter for optimal performance of any PV system.

Overall, the EET-UQ2W331DA aluminum electrolytic capacitor is an ideal device for use in photovoltaic systems where high ripple currents and high temperatures are a concern. With its high capacitance, low ESR values, and wide temperature range, it offers many advantages at an affordable cost.
