Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors, commonly known as \'electrolytics\', are capacitors that often exist as two aluminum foils, one coated with an oxide layer, and the other with a thin wet liquid electrolyte. Their strong points are their high capacitance per unit volume and cost, which also make them the most widely used capacitors in electronic applications. B41693A5477Q7 is such an Aluminum Electrolytic Capacitors from TDK Corporation, a well-established company in the fields of capacitors and electronics.

B41693A5477Q7 Application Fields and Working Principle

B41693A5477Q7 is a Longlife Polarized Aluminum Electrolytic Capacitor which is particularly suited for use in various types of lighting applications. It has low ESR and high capacitance, and due to its low equivalent series resistance, it provides high power-handling capacity in wide range of electrical devices. The capacitance of this product varies from 0.047uF to 220uF depending on the operating temperature, and its operating voltage range is up to 450V DC.

The primary working principle of B41693A5477Q7 is based on Faraday’s law of electrolysis. As the current passes through the solution, it undergoes an electric field, which causes ion migration through the electrolyte. In the process, a thin film of oxide forms on the surface of the aluminum foil, which acts as an insulator. This process of assembling an oxide layer is where the capacitance of the capacitor is attained.

The electrical charge is stored in the oxide layer, which is the medium of charge transfer between the two metallic foils, known as plates. The operation of this capacitor usually involves charging one plate and discharging another, or vice versa, thus allowing current to flow through the electrolyte. This creates a capacitance between the two plates, which is determined by the surface area, the distance between the plates, and the thickness of the oxide layer.

The capacitor also has a large dielectric constant, which allows it to act as an insulator with a low leakage current. The dielectric properties also provide good stability, a long life and a high reliability. Moreover, these capacitors usually have a high ripple current rating that allows them to handle high-frequency current without significant losses.

As a result, this product is extremely light-weight and cost-effective, so it is widely used in various consumer electronics, medical electronic equipment, LED lighting, power factor, and motor control applications. Furthermore, compared with other capacitor products in the same category, B41693A5477Q7 demonstrates superior performance, making it an ideal choice for most electronic applications.
