Aluminum electrolytic capacitors are an essential type of component found in nearly every electronic device. The UPW1V471MPH is an example of this type of capacitor, and it is used in an array of different applications. This article provides an overview of the UPW1V471MPH\'s field of applicability and its working principle.

The UPW1V471MPH is a radial-lead aluminum electrolytic capacitor that is designed for use in telecommunications and general-purpose switching applications, as well as other general-purpose circuits. It has a maximum voltage of 63V, which makes it suitable for power supply capacitors, audio filter capacitors, and camera flash functionality. Additionally, its wide temperature range (-55ºC to +105ºC) makes it ideal for outdoor applications.

Structurally, the UPW1V471MPH is made up of three layers, including two capacitance metallized layer foil electrodes and an electrolytic paper spacer. The electrodes\' construction is key to the capacitor’s functionality, as it facilitates an increase in surface area and, as a result, promotes higher current densities. Furthermore, the use of a conical-shaped outer shell results in an optimal body diameter-tolerance relationship, in turn increasing the capacitor’s ability to absorb temperature-induced stress with less mechanical distortion.

In addition to its design, the UPW1V471MPH also features a series of safety features, including radial lead wire insulation and safety venting technology. Safety venting works by incorporating a thin membrane into the capacitor, allowing for the release of pressure in the event of overvoltage or other abnormal events. This type of safety feature minimizes the risk of explosions or fires.

The working principle of the UPW1V471MPH is based on the fact that two metal foils are separated by a film of electrolyte. When an electrical current is passed through the capacitor, the formation of an electric double layer occurs at the contact points between the metal foil and the electrolyte, creating an electric field between them. This electric field stores electrical energy in a space charge and acts as a barrier to the flow of current. This is the same principle used in all types of capacitors.

In summary, the UPW1V471MPH is an aluminum electrolytic capacitor that is used in a variety of applications, including telecommunications, general-purpose switching, and camera flash. It features a maximum voltage of 63V and a wide temperature range of -55ºC to +105ºC. It is made up of three layers and incorporates safety features such as radial lead wire insulation and safety venting technology. The working principle is based on the fact that two metal foils are separated by a film of electrolyte, creating an electric field between them.
