Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are basically two metal plates separated by a liquid or solid electrolyte. An electric field is created in the electrolyte when a voltage is applied, which produces a charge separation, and a capacitor is formed. The aluminum electrolytic capacitor is created by using two aluminum foils, one coated with an insulating oxide powder. The other foil is a pure aluminum foil. Between the two is an electrolyte, which is typically a springy material and provides structural support to the capacitor.

B41458B8689M003 Application Field

The B41458B8689M003 aluminum electrolytic capacitor is a small, chip-shaped surface-mount (SMD) device. It is an ideal choice for many applications, including power supplies, regulators, system clocks, voltage converters, and input/output (I/O) power for PCs and servers. This capacitor has an extremely low ESR rating, so it can handle large voltage surges, making it well suited for automotive and industrial applications.

B41458B8689M003 Working Principle

The B41458B8689M003 aluminum electrolytic capacitor features an electrolyte composed of a metallic oxide film. This metal oxide film works as an insulator, and it consists of a cathode and an anode separated by an electrolyte. When AC power is applied to the capacitor, electrons are transferred from one side to the other, creating an electric field and causing a current to flow. The current creates an electrostatic force that causes certain ions from the electrolyte to move and form a charge separation. This charge separation creates a voltage across the capacitor, causing a capacitor to store electrical energy.

The B41458B8689M003 also features extremely low equivalent series resistance (ESR), which allows it to handle high current and voltage surges. In addition, the metalized film construction ensures an extremely low capacitance loss, offering superior stability and reliability in output. This capacitor also features a temperature range of -40°C to +105°C for harsh environments, making it well-suited for a wide variety of applications.
