Aluminum Electrolytic Capacitors – B41828B5338M Application Field and Working Principle

Aluminum electrolytic capacitors, also known as electrolytic capacitors or aluminum capacitor, are polarized capacitors whose anode is composed of an aluminum oxide layer, which acts as a dielectric, on top of which lies a layer of aluminum foil. The type of capacitors that use aluminum electrolytes are generally known as aluminum electrolytic capacitors, and are one of the most widely used capacitors in electrical and electronic equipment.

Aluminum electrolytic capacitors are valued for their high volumetric efficiency, large capacity, low price, and characteristic of capacitance increase with increases in operating voltage. They are often used in high-current low-resistance applications such as Japanese dimmer switches. In addition to this, they are also used for power supply filtering, bypassing, buffering, coupling, and other similar applications.

The B41828B5338M aluminum electrolytic capacitor is a type of surface-mount aluminum electrolytic capacitor specifically designed for high frequency, high ripple current applications in power supplies, telecommunications, and consumer electronics. It is rated for a voltage of 10 VDC, has a capacitance of 47µF, and is RoHS (Restriction of Hazardous Substances) compliant. It is also a low-impedance type with a moisture absorption rating of 1.4. Its features make it suitable for a wide range of applications including as a decoupling capacitor and a buffering device.

Looking into the working principle of an aluminum electrolytic capacitor, electric energy is stored in the device by separating positive and negative charges. This is done by having one of the aluminum layers plates having an oxide coating that acts as the dielectric that allows electric charge to be stored inside the capacitor. This layer of oxide is achieved by submerging the plate in an electrolytic solution such as diluted sulfuric acid, applying a current, and allowing the oxide to form on the aluminum plate during the process. As the oxide layer builds up, the positive ions of the solution become concentrated in the vicinity of the oxide-coated plate, creating an electric field. This electric field is what stores electric energy and allows the capacitor to charge. When a voltage potential is applied between the positive and negative plates, the charge begins to spread from the positive plate to the negative plate and eventually discharges through them.

In summary, the B41828B5338M aluminum electrolytic capacitor is an invaluable component used in the development of a wide variety of electronic devices. Its large capacitance and excellent volumetric efficiency make it highly suitable for filtering, buffering, decoupling, and other applications. Its working principle takes advantage of the metal-oxide-metal structure of the capacitor, allowing for the separation and storage of electric charges within the device. With its excellent features and high performance, it is no wonder why it is one of the most widely used capacitors today.
