Aluminum-Polymer Capacitors are a family of electrolytic capacitors made up of two different electrodes. The first electrode is aluminum which conducts energy, while the second electrode is composed of a highly porous polymer material. This combination of materials makes the capacitor highly stable, reliable and efficient.

EEF-UE0J181R is a family of aluminum-polymer capacitors, which is a high-end series in the market. Its capacitance is up to 2.2µF with rated voltage of 10Vdc and a long life up to 5000h. In terms of construction, the EEF-UE0J181R consists of a cylindrical outer casing, a core and a coil. The core is made up of a highly porous polymer material, which ensures low power loss. The spiral coil is made of an aluminum sheet that is ENIG plated for additional reliability. In addition, the EEF-UE0J181R is also properly protected from oxidation with a passivation layer and a coating that prevents corrosion.

The main application of the EEF-UE0J181R is in power electronic applications as it provides a low leakage current along with high energy storage capability. Due to its high capacitance value, the EEF-UE0J181R is often used in high power switching converters, such as DC-DC converters and UPS systems, allowing for higher power support with improved power efficiency. Also, thanks to its excellent damping capability, the EEF-UE0J181R is often used to stabilize power ripple in motor drives, improving their stability and reliability.

The working principle of the EEF-UE0J1811 is based on the “double layer” effect. This effect is achieved through a combination of the highly porous polymer material and the ENIG gold plated aluminum sheet. The aluminum layer will act as the anode, accepting electrons through the ENIG plating and the polymer layer acts as the cathode, releasing electrons. This process will result in an electric field between the two layers, generating a current in the circuit. This current is known as the “double layer” effect and it is what allows the EEF-UE0J181R to have high capacitance properties and high energy storage capacity, making it ideal for power electronic applications.

In conclusion, the EEF-UE0J181R is a high quality aluminum-polymer capacitor that provides excellent characteristics and benefits for power electronic applications. It has a high capacitance and excellent energy storage properties, along with a long life and high power efficiency. Additionally, the EEF-UE0J181R also features improved stability and reliability, thanks to its damping capability and robust construction. All these features make the EEF-UE0J181R an ideal choice for power electronic applications, such as DC-DC converters, UPS systems, and motor drives.
