Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are capacitors with an extremely high energy density (relative to other capacitor types) and are commonly used in electronic equipment and other applications. They are a type of double-layer capacitor and consist of an aluminum oxide film on an aluminum foil substrate, separated by a unique electrolyte layer. The aluminum oxide film acts as the dielectric layer of the capacitor, with the production of an anodized layer providing additional stability and corrosion protection. The electrolyte, typically an organic solvent-based electrolyte, provides the charge-carrying medium between the two surfaces. An applied voltage causes a charge to be deposited onto one of the plates.

The UVR1V471MPA is one of these high quality aluminum electrolytic capacitors, and is designed for applications such as signal, power, and installation use in both consumer electronics and automotive industries. It is rated to a temperature range of -25°C~+85°C with a capacitance value of 4.7 μF. This capacitor is available in both surface mount and radial-lead packages.

Despite its relatively small size, the UVR1V471MPA is highly capable of handling high frequency operations up to a maximum frequency rating of 2,500 kHz. This makes it an ideal choice for a variety of applications that require high capacitance with high frequency switching and power supply stability.

The working principle of the UVR1V471MPA is relatively simple and straight forward. When a voltage is applied to the capacitor it applies an electric field between the plates, which causes electrons to move from the negative plate to the positive plate. This movement of electrons creates an electrostatic field that stores energy, which can then be released when needed. When a larger magnitude and/or a longer duration of voltage is applied, the capacitor enters into a state known as over-voltage and the current entering the capacitor is limited, preventing it from becoming damaged.

In general, aluminum electrolytic capacitors are highly reliable and easy to use. This is due to their construction and electrolyte-based design, which help to ensure that the capacitance is maintained over time. Also, as the UVR1V471MPA is a type of aluminum electrolytic capacitor, it is no exception and provides a great level of performance from its compact size.
