UFW1E472MHD

Aluminum electrolytic capacitors are one of the oldest and most widely used types of capacitors in the industry, they possess relatively large capacitance values in a small volume and are mostly used in power circuits, i.e. DC power supplies. The UFW1E472MHD capacitor is a radial aluminum electrolytic capacitor with a capacitance of 47µF, a voltage rating of 25V, and a permissible ripple current of 130mA. It is also considered a Leakage Current (LC) type capacitor as it is crafted with a unique electrolyte that holds extra capacity to absorb LC. It is an ideal choice for applications with low impedances and high frequencies, especially in low-voltage circuits.

Working Principle

In aluminum electrolytic capacitors, the main component is an aluminum oxide layer which acts as the dielectric. The aluminum oxide layer is created through a process known as anodizing, which consists of submerging an aluminum cathode into an electrolyte solution, applying a voltage, and allowing oxide to form on the surface. In the UFW1E472MHD capacitor, the electrolyte is composed of a mixture of ethylene and glycol which ensure increased performance and a longer life span. The oxide layer acts as a dielectric and acts as insulator to store energy when voltage is applied to the capacitor.On either side of the oxide layer, two simple metallic aluminum foils act as electrodes. The electrolyte solution stored between the oxide layer and the electrodes provides a leakage current path. In electrolytic capacitor design, the electrolyte needs to permeate the epoxy-sealed, metalized Mylar film which separators before reaching the electrodes. The separation process period is known as the break-in period, and it is necessary for the electrolytic capacitor to be properly polarized during this period.

Application Field

The UFW1E472MHD capacitor is mostly used in applications with low impedances and high frequencies, such as low-voltage power supplies, radio frequency circuits, and various automotive and industrial applications. Due to its LC feature, it is also a great choice in situations where the capacitance needs to be constant in relatively low impedances. By virtue of the capacitor\'s low ESR (Equivalent Series Resistance), it offers low dissipation and improved performance in circuits with high frequencies, hence providing high ripple-current handling. The UFW1E472MHD capacitors can be found in a variety of automotive applications such as DC-DC converters, switch-mode power supplies, power supplies for radios, remote control systems, and electromagnets for seat positioning. In industrial applications, these capacitors are used in communication systems, air conditioning and cooling systems, lighting systems, and in various other types of power supplies. In summary, the UFW1E472MHD aluminum electrolytic capacitors are meant to be used in applications where low impedance, high frequency, and a stable capacitance is required. The electrolyte between the oxide layer and the aluminum foils grants the capacitor its leakage current, which allows for the capacitor to maintain a stable capacitance in low impedances. Due to its small size, this capacitor is perfect for cramped conditions, and its use in a variety of automotive and industrial applications proves that it is a reliable and dependable choice.
