Aluminum Electrolytic Capacitors

160YXF15KEFCT78X11.5 is a type of aluminum electrolytic capacitor, a polarized electrolytic capacitor, which features a very wide capacitance range, extremely small size and a unique construction. It consists of two electrodes, the anode made of aluminum and the cathode made of a metal-oxide. These two electrodes are wrapped in paper, and the cathode is then sealed to the aluminum foil and to the dielectric. And the electrolyte is a solution of organic acids.

Application field

Due to its large capacitance, high temperature stability and a wide range of possible sealing techniques, aluminum electrolytic capacitors are perfectly suitable for use in high-end audio, power supplies, automotive and aerospace electronics.

Also, they have a number of other areas of application, such as in medical and industrial instrumentation, electric motors, motion control, and communication systems.

Working Principle

Aluminium electrolytic capacitors work on the principle of dielectric absorption. That means that the dielectric layer in between the two electrodes absorbs electrons from one of the two electrodes and releases the same electrons to the other electrode. This process of electron transfer creates a capacitive effect, which is used to store a certain amount of electrical energy.

The principle also allows the capacitor to react to a very wide range of frequencies, which makes aluminium electrolytic capacitors particularly suitable for use in a variety of applications where a high capacitance, high temperatures, and small sizes are required.

It is also important to note that aluminum electrolytic capacitors can be very precise in their operation, and they can be designed for very specific applications. For instance, many capacitors are designed to have very low ESL and ESR, which is important for high-end audio and other applications.
