Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, or just electrolytic capacitors, are electronic components that provide a specific amount of capacitance, most commonly used in applications where a steady flow of electric current is required. These capacitors are constructed with two electrodes, an electrolyte, and an electrically insulating material, typically in the form of a paper dielectric film. The result is an extremely efficient device that provides superior electrical characteristics in a variety of uses.

B41554E9338Q000 Application Field

Aluminum electrolytic capacitors are designed for a wide range of applications, including: power supplies, digital circuits, analog signal processing, data transmission, and industrial automation. The B41554E9338Q000 is rated for use in AC-DC power supply, DC-DC converter, and variable frequency drive (VFD) applications. It offers a rated voltage of up to 400V, a low equivalent series resistance (ESR), and a high ripple current rating. This makes it ideal for applications that require high current surge protection, low voltage deviation, and fast response time.

B41554E9338Q000 Working Principle

Aluminum electrolytic capacitors, including the B41554E9338Q000, consist of two layers of aluminum oxide, separated by an electrolyte material and an electrically insulating dielectric film. When a voltage is applied, an electrical charge passes through the electrolyte and causes an atom to move to one end of the capacitor, forming a ‘charge’. This charge remains until the voltage is removed.

The capacitance of the capacitor depends primarily on the area of the aluminum oxide layers. The higher the area, the higher the capacitance. The capacitance also depends on the thickness of the dielectric film, the type of electrolyte, and the temperature of the surrounding environment.

Aluminum electrolytic capacitors have excellent characteristics such as high capacitance, low ESR, high ripple current rating, and low temperature coefficient. They also have a relatively long service life and are available in a variety of sizes.
