Aluminum electrolytic capacitors are electronic components that can store electrical energy just like a battery. Its basic component is an electrolyte composed of an aqueous solution of an ionic material such as sulfuric acid or potassium hydroxide. This electrolyte is surrounded by two aluminum foils each of which is tightly rolled up like a jelly roll with an porous insulating material separating them. The electrolyte provides electrical connection between the two aluminum foils by making them the two poles of the capacitor. A dielectric material such as a paper or foil is also connected between the two aluminum foils for insulation.

MAL211938109E3 is an aluminum electrolytic capacitor which is designed for use in electrical appliances and circuitry. It is made of high quality aluminum and can tolerate a high frequency and capacitance range up to 40μF with a maximum operating temperature of 105°C. The MAL211938109E3 capacitor has a diameter of 19 mm and a height of 38 mm, making it suitable for small, space-saving electronic components. It is also capable of handling higher voltage pulses due to its built-in features.

The main application areas utilizing MAL211938109E3 capacitors are circuitization, audio applications, battery powering, and motor control/operating systems. While applications where low ESR conditions are required rely on this type of capacitor. In automotive electronics, capacitor ripple current rating is often a crucial defining feature, and MAL211938109E3 provides a wide range of values which are based on capacitor volume.

In terms of its working principle, the MAL211938109E3 capacitor is a polarized device. When connected to DC power source, the electrons move from the positive to the negative electrode, creating an electric field between the two electrodes. This electric field causes the capacitor to store energy, allowing current to flow through the circuit as needed. In an alternating current circuit, the electrons move back and forth from positive to negative and then back to positive, and this movement creates an electric field which causes the capacitor to store energy.

Whenever a current passes through the capacitor, it passes through the dielectric material, which stores the energy. The energy stored in the dielectric material is then discharged as particles pass through the dielectric causing an electric current to flow through the capacitor. This current flow allows the charging of the circuit and causes the capacitor to store energy again. This back and forth action continues creating an alternating current, which is responsible for the charging of the capacitor.

Overall, the MAL211938109E3 is an efficient aluminum electrolytic capacitor designed for home appliances and circuitry operating at high frequencies and voltage pulses. It is suitable for use in audio components, automotive systems and other circuit applications. Its features offer strong reliability and protection against overvoltage, making it an ideal choice for designers of electronic circuits.
