Aluminum electrolytic capacitors are one of the most common and reliable types of capacitors. They are widely used in a variety of applications and are typically small in size and relatively inexpensive. EET-UQ2W181HA is one of the popular aluminum electrolytic capacitors, which offers a voltage range of 1.5-63V, a capacitance range of 1-3,700uF and a ripple current range of 13-1460mA.The aluminum electrolytic capacitor consists of two electrodes separated by a layer of aluminum oxide. The aluminum electrode is etched from high-purity foil and is wound into a coil. The other electrode is typically a terminal plate connected to the metallic can of the capacitor which also serves as the negative terminal of the capacitor. The aluminum surface of the dielectric constant is seized by an electrolyte solution. This is done to increase the capacitance of the capacitor by increasing the surface area of the aluminum oxide material. The electrolyte also increases the voltage rating of the capacitor by providing higher electric field strength in the capacitor.The EET-UQ2W181HA aluminum electrolytic capacitor is ideal for circuit applications that require high ripple currents due to its high ripple current ratings. It is also suitable for applications with high frequency or high temperature due to its low ESR and low temperature drift. It is also able to withstand higher working temperatures and can be used in a wide temperature range.The working principle of an aluminum electrolytic capacitor is based on electrical double layer. When a voltage is applied across the electrodes of the capacitor, electric current flows through the electrolyte which creates a charge separation layer on the aluminum oxide surface. This creates a phenomenon known as an electrical double layer. This double layer stores electrical energy and forms an electric field between the electrodes causing a capacitance between them.The EET-UQ2W181HA aluminum electrolytic capacitor is commonly used in applications such as switching power supplies, adjustable speed drives, measurement instruments and AC line filters. It offers excellent performance, reliability and low leakage current, thus making it an ideal choice for these demanding applications.In conclusion, the EET-UQ2W181HA aluminum electrolytic capacitor is one of the most reliable and cost-effective solutions for a variety of applications. It offers excellent performance, reliability and low leakage current, thus making it an ideal choice for demanding applications where high-voltage and high-current capabilities are required.
