Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, often referred to as electrolytic capacitors, are electrical components used to store energy electrostatically and release it as an electrical current. The UHE1H471MPT is an aluminum electrolytic capacitor that is used for the applications mentioned below and has a working principle that is described in detail in this article.

Types and Categories of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are available in a variety of different types. These components can be categorized according to their construction, voltage, and capacitance. Generally, they are divided into radial lead and snap-in style capacitors. Radial lead capacitors are those that have two identical leads that extend in opposite directions from either side of the capacitor. These capacitors typically have a larger package size and lower leakage current and ESR compared to their snap-in counterparts. Snap-in capacitors are those that come in a single package with all of the terminals located on one side of the device. These capacitors have a smaller package size and higher leakage current and ESR. The UHE1H471MPT is a radial lead aluminum electrolytic capacitor.

Voltage

In addition to the type of construction, the voltage rating of a capacitor is another important factor to consider when choosing the right component for the application. In general, aluminum electrolytic capacitors are available in rated voltages of 25V to 700V. The UHE1H471MPT is rated for 100V.

Capacitance

The capacitance of a capacitor is the amount of electrical energy that can be stored in the device. These components are usually rated in microfarads (µF) and range from 1µF to 4700µF. The UHE1H471MPT is rated for 470µF.

UHE1H471MPT Application Field

The UHE1H471MPT aluminum electrolytic capacitor can be used for a variety of applications, ranging from power supplies, frequency conversion circuits, and noise filtering. These applications require a capacitor with a high capacitance, low equivalent series resistance (ESR), and high ripple current. The UHE1H471MPT has an ESR of 0.019 Ohms, a ripple current of 500mA, and a capacitance of 470µF; making it an ideal component for these types of applications.

UHE1H471MPT Working Principle

Aluminum electrolytic capacitors work by using the combination of an anode, electrolyte, and a gate material. The anode is made from aluminum foil that has been etched to form a pattern of microscopic pores. This allows for increased surface area and allows for the electrolyte to be stored in the device. The electrolyte, typically composed of boric acid and alcohol, holds the charge and conducts electricity when the gate material is applied. The gate material, usually an aluminum oxide film, is formed when electrons from the electrolyte attach to the aluminum anode and an electric field is formed. This electric field stores energy, allowing the capacitor to store and release an electrical current.

Conclusion

The UHE1H471MPT aluminum electrolytic capacitor is an excellent choice for applications requiring a capacitor with a high capacitance, low ESR, and high ripple current. Its construction and functioning principles make it a reliable choice for powering, filtering, and converting electrical signals.
