Aluminum electrolytic capacitors are common electrical components found in many circuits. They are used to store energy, block high frequency signals, and for filtering and coupling applications. The MAL212325479E3 is a radial-style aluminum electrolytic capacitor with an operating temperature range between -55°C and 125°C. It features a voltage rating of 25V, an ESR of 0.15 ohms, a ripple current rating of 5.3A, and a capacitance of 470uF. This capacitor is designed to be used in automotive, power supply, and lighting applications.

An aluminum electrolytic capacitor consists of two leads connected to a wound aluminum foil separator that contains a liquid electrolyte. These components act as a dielectric between the two aluminum plates. When an electric current is applied, ionization occurs in the electrolyte and a thin oxide layer is created on the aluminum foil. This acts as a reversible interlayer between the aluminum plates which creates an electric field between them and stores electrical energy.

The operating principles of the MAL212325479E3 aluminum electrolytic capacitor are based on the use of electrolytes and oxidation of aluminum foils. When a current is passed through the capacitor, oxidation of the positive electrode produces ions that are attracted to the negative electrode. These ions deposit on the negative electrode, forming an oxide layer. This layer acts as a dielectric between the plates, storing electrical energy.

The MAL212325479E3 is a versatile component with multiple applications, including automotive, power supply, and lighting circuits. It is widely used in automobiles, such as in engine control modules, airbag control units, and ABS systems. In power supply applications, it is used to filter AC ripples and stabilize electric outputs. In lighting systems, it provides a steady output to reduce flicker.

In summary, the MAL212325479E3 is a radial-style aluminum electrolytic capacitor with a capacitance of 470uF and a voltage rating of 25V. It has a wide operating temperature range and is designed for automotive, power supply, and lighting applications. Its operating principles are based on electrolytes and oxidation of aluminum foils. It can be used to filter AC ripples, regulate electric outputs, and reduce flicker in lighting systems.
