Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as wet electrolytic or electrochemical capacitors, are polarized capacitors consisting of a series of aluminum foils separated by paper or plastic film and connected with a liquid electrolyte. They have high capacitance and high voltage ratings making them ideal for many applications. The UVY1E472MHD is an aluminum electrolytic capacitor manufactured by Vishay Intertechnology.

UVY1E472MHD Application Field and Working Principle

The UVY1E472MHD is a four-terminal, axial-leaded, aluminum electrolytic capacitor with a four-pole design. Its capacitance of 4.7uF, voltage rating of 50V, temperature range of -55°C to 85°C, and impedance from 17mΩ to 26mΩ make it suitable for a range of wide-ranging applications.The working principle of the UVY1E472MHD is based on the Faraday principle of electrolysis. When a voltage is applied across the terminals of the capacitor, electrons flow from one metal plate to the other through the electrolyte, creating an electric field within the capacitor which stores an electrical charge. The voltage on the capacitor is determined by the ratio of the metal plates in contact with the electrolyte and the amount of charge stored by the aluminum electrolytic capacitor.The four-pole design of the UVY1E472MHD provides superior energy storage compared to two-pole designs. This allows it to handle higher ripple current and gives the capacitor greater temperature stability. The four poles also reduce self resonance, resulting in lower capacitance variation over temperature and better ESR values.The UVY1E472MHD aluminum electrolytic capacitor is designed for use in portable consumer electronics, automotive, industrial and medical applications, as well as frequency conversion and filter circuits. It is suited for applications where low-loss energy storage is required, such as power supplies and energy storage devices. Additionally, due to its compact size, the UVY1E472MHD is ideal for applications where space is a concern.
