Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that utilizes an aluminum oxide film as the dielectric material. This type of capacitor, like most others, is composed of two electrical conductors separated by an insulating dielectric material, with a valence charge layer on one side forming the insulator. The primary difference between aluminum electrolytic capacitors and other types of capacitors is the use of a liquid electrolyte solution as the electrolyte and charge carrier. This creates the ideal conditions for the rapid transfer of free electrons between the two electrodes.

860040580019 Application Field and Working Principle

Aluminum electrolytic capacitors have a wide range of uses, such as for storage and signal processing applications. They are often used in switching power supplies, audio amplifiers, motor control circuits, and profusion lighting systems. The use of aluminum electrolytic capacitors can improve signal quality, reduce power dissipation, and increase the reliability of a system due to their low internal impedance and high frequency response.

The working principle of an 860040580019 aluminum electrolytic capacitor is similar to other capacitive devices. It is composed of two plates, separated by a dielectric material, with a valence charge layer on one end that forms the insulating barrier between the two plates. The electrical current flows in a circular path with the positive charges on the one side and the negative charges on the other in a circuit. As the voltage is applied across the capacitor, the electrical field drives the electrons from one plate to the other, resulting in a positive charge stored on the first plate and a negative charge stored on the second plate.

Once the voltage has been applied to the capacitor and equilibrium is reached, no net current can flow through the capacitor and thus it is said to be polarized. The voltage rating of the 860040580019 aluminum electrolytic capacitor must not exceed the voltage rating of the capacitor itself; otherwise, the capacitor may become damaged or even destroyed due to the high reverse current flow.

Aluminum electrolytic capacitors feature greater temperature and frequency stability compared to ceramic and plastic film capacitors. Furthermore, they are more compact and can store up to four times more energy than other types of capacitors. In fact, this particular 860040580019 model has a high energy density, low ESR and high ripple current, making it ideal for use in high power applications.

Aluminum electrolytic capacitors are highly reliable, offering a long operating life, even under severe conditions. They offer excellent surge current capabilities, are vibration and shock resistant, and are available in a wide range of capacitance values from several hundred microfarads to over one thousand microfarads.

Due to the performance of aluminum electrolytic capacitors, they are a reliable choice for use in many applications, from high power LED lighting systems, consumer electronics, industrial automation, audio amplifiers to medical instrumentation.
