Aluminum electrolytic capacitors are polarized electrical components that have a wide range of applications, ranging from power conditioning and consumer electronics to medical instrumentation and communications. The URY2F220MHD aluminum electrolytic capacitor is an example of a device that is specifically designed for power conditioning applications.

Specifications

The URY2F220MHD capacitor is principally designed as a bi-polar device with a high performance capability and extended temperature range. This allows it to be applied in power conditioning and other demanding applications. The rated voltage for the device is 350V, and the rated capacitance is 220μF. The device has a maximum height of 25mm and a maximum diameter of 13mm. The temperature range can extend up to 80°C.

Construction

The URY2F220MHD capacitor is a bi-polar aluminum electrolytic capacitor constructed of two main elements. The first element is an anode consisting of a two-layer aluminum foil cylinder. This cylinder is then wrapped with a microporous paper soaked in a liquid electrolyte to form the dielectric layer. The second element is a cathode consisting of a platform of aluminum oxide which is formed in situ during the production process. Both elements are sealed in an aluminum shell with a plastic cap to provide protection from external electrical fields.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on the physics of electrical capacitance. When a voltage is applied to the capacitor, a capacitive current appears across the anode and cathode electrodes. This creates an electric field that stores energy in the form of a polarized electric charge. As the field builds up, the electric charge on the anode builds up until it is equal to the field at the cathode electrode. When this occurs, the capacitor has reached its rated voltage.

Application Field

The URY2F220MHD capacitor is primarily designed for use in power conditioning and communications applications. In power conditioning applications, the capacitor is used to store and release energy as needed, allowing the system to maintain its voltage levels at low and high frequencies. This makes the capacitor an ideal choice for applications such as power conversion, motor control, inverter sizing and power factor correction. In communication systems, the capacitor can be used to filter out noise and provide improved signal integrity. Additionally, the capacitor can be used in circuit designs where input power is limited.
