Aluminum Electrolytic Capacitors (also known as Aluminum Electrolytic Capacitors, AECs) are a type of capacitor that uses an insulating aluminum oxide film to store electrical energy. They are used for a wide range of applications, from signal processing circuits to electric power grids.

The MAL203871229E3 is a high-temperature, low-impedance, and snap-in aluminum electrolytic capacitor, suitable for use in various equipment such as industrial and medical equipment, automotive electronics, and aircraft.

Application field

The MAL203871229E3 is a popular option in the industrial and medical equipment markets, due to its high temperature performance, durability, and high ripple current capability. It is also suitable for consumer electronics, automotive electronics, and aircraft, due to its low impedance. This capacitor is also well-suited for use in high-voltage power supplies and in high-frequency applications.

Working principle

The working principle of aluminum electrolytic capacitors is based on the Faraday effect, which states that when a voltage is applied across two plates separated by an electrolyte, a current will flow through the electrolyte due to an electric field. The electrolyte causes ions to be attracted to the positive plate, while electrons are attracted to the negative plate. This creates an electric dipole, which stores energy in the form of an electric field and magnetic field.

The MAL203871229E3 uses a wet-paper-backed aluminum foil cathode and an anode made of an anodic oxidation layer. When voltage is applied to the capacitor, the wet paper absorbs the electrolyte, creating an electric field which causes the aluminum foil to swell and create a strong physical connection between the two electrodes. This connection creates a low impedance, which allows the capacitor to have a high ripple current capability and high temperature performance.

The Faraday effect also serves to create a highly reliable electrical connection between the two electrodes. This helps reduce the risk of short circuits, corrosion, or other types of damage due to moisture or electrical exposure.

The MAL203871229E3 is also designed for high-frequency use. The design features an inner component with a higher capacitance, which improves the performance at higher frequencies. This makes the capacitor suitable for use in signal processing, RF electronics, and other applications requiring a high-frequency response.

The MAL203871229E3 offers a wide range of options for industrial and medical equipment, automotive electronics, and aircraft. The capacitor\'s high temperature performance, low impedance, and high-frequency response make it an ideal choice for these applications.
