Aluminum electrolytic capacitors use aluminum foil as their anode material and an electrolytic paper as their dielectric medium. They are mainly used in applications that need high capacitance and high energy density, such as pulse and switching power supplies, audio power amplifiers, and high-voltage applications. The SEK471M050ST aluminum electrolytic capacitor is a surface-mount device that is specifically designed for use in commercial and consumer applications.

The SEK471M050ST aluminum electrolytic capacitor offers a high amount of capacitance in a small package. It has a maximum capacitance of 4700μF, a working voltage rating up to 50V DC and a temperature range between -25 to 105°C. It is built with a self-healing process, making it more suitable for high-reliability applications and harsh environments. The capacitance value of the SEK471M050ST is mark with a color code, making it easier to identify and use it in a wide range of projects.

The SEK471M050ST aluminum electrolytic capacitor has an operating frequency range between 200KHz and 2GHz. It is able to withstand up to 300% overload, making it suitable for heavy-duty applications. Its low ESR and ESL, combined with its high ripple current rating and high temperature operating range, makes it perfect for use in audio power amplifiers, telecommunications, and switching power supplies.

How the SEK471M050ST aluminum electrolytic capacitor works is simple. It uses an anode material made of aluminum foil and its dielectric material consisting of a electrolytic paper. When a voltage is applied across the capacitor, an electric field develops between the plates, which induces an accumulation of electrons at the surface of the anode. This creates an electric charge between the two plates, and this electric field acts as a barrier to current flow.

The capacitance of the SEK471M050ST aluminum electrolytic capacitor is determined by the surface area of the plates, the allowable voltage, and the dielectric constant of the paper. It is able to handle higher frequencies, as well as higher voltages, due to its structure and material composition. It is also suitable for use with ac and dc power supplies, as it is able to withstand up to 300% overload.

The SEK471M050ST aluminum electrolytic capacitor is a reliable, versatile and efficient device that can be used in a variety of applications. It is commonly used in commercial and consumer applications due to its high capacitance and low price. It is also suitable for use in audio power amplifiers, telecommunications, and switching power supplies due to its high ripple current rating and wide operating temperature range.
