Aluminum-Polymer Capacitors (EEF-UE0G271LE) are a type of capacitor that incorporates an aluminum-electrolytic capacitor and a polymer-electrolytic capacitor into one. These capacitors have been popular since the 1980s, with the first proving to be highly reliable and suitable for a wide range of applications. The combination of aluminum and polymer makes these capacitors an attractive choice, as they offer increased capacitance, higher voltage capabilities, improved inrush current penetration, and improved temperature performance in comparison to aluminum electrolytic capacitors. In addition, they are more robust and durable than traditional aluminum-electrolytic capacitors, making them an attractive choice for various industrial and commercial applications.

The most common type of Aluminum-Polymer Capacitor is the EEF-UE0G271LE. This type of capacitor has a rated temperature range of -40°C to 125°C, with a rated voltage of 315V. Additionally, the EEF-UE0G271LE has a rated capacitance of 27000μF, which is quite high for a capacitor of this size. These capacitors are encapsulated in epoxy resin and feature a nickel-plated steel can housing for increased durability. The main manufacturer of EEF-UE0G271LE capacitors is ELNA.

The working principle of Aluminum-Polymer Capacitors may differ depending on the design and application. Generally speaking, however, the electrical component uses an anode and cathode to form two distinct parts within the capacitor, resulting in a two-pole structure. The two polar parts are typically separated by a dielectric material, which is insulated and dielectrically sealed. When a current is applied, charge accumulates on one side of the capacitor and decreases on the other, creating an electric field. This electrical field causes an electric charge to flow between the two poles and the dielectric material helps to contain the charge.

The main application area for Aluminum-Polymer Capacitors is in power electronics. They are often used to store energy in high-power devices such as motors, electric vehicles, and power system equipment. Their high capacitance makes them ideal for applications that require high levels of current. Additionally, they can be used for filtering, bypassing, and power smoothing, making them indispensable in electric systems. EEF-UE0G271LE capacitors can also be used for AC to DC conversion and applications requiring large capacitance values.

In conclusion, Aluminum-Polymer Capacitors are well-rounded components that offer a wide range of features and benefits not found in other types of capacitors. The EEF-UE0G271LE type offers superior performance and long-term reliability, making it an ideal choice for many industrial and commercial applications. With its high capacitance, excellent temperature stability, and large voltage rating, the EEF-UE0G271LE is an excellent choice for power electronics, AC to DC conversion, filtering, bypassing, and power smoothing.
