Aluminum Electrolytic Capacitors (AECs) are an important family of Passive Electronic Components, typically consisting of two featureless aluminum foils (anode and cathode) which are separated by a thin layer of electrolyte, and an epoxy-coated paper-like material (called an “ insulating paper”). The two foils are usually further separated by an insulating diaphragm, and there are often several different types of insulating materials in use.

The self-healing feature of AECs makes them a popular choice for many applications, ranging from audio applications to high voltage DC/AC filter circuits. The self-healing feature is the result of the positive formation of an oxide layer, which is created by the natural flow of electricity within the capacitor. This positive formation constitutes a microscopic layer of protection for the capacitor, in that the area is no longer affected by the application\'s direct current and therefore will not experience any further depletion of the oxide layer. However, this means that the aluminum foil must be of large enough thickness to enable the oxide layer to form in the first place.

The ALS70A134KE025 is one such AEC with a maximum working voltage of 65VDC. It is a low impedance device that is primarily designed for use in audio/video applications, providing a high frequency compensation as well as a low ESR design that helps reduce the current flow through the capacitor. It also features a high temperature polyester dielectric, which helps to improve its performance in high temperatures, while also providing increased stability.

In terms of its working principle, the ALS70A134KE025 works by developing a charge on the electrode when an external voltage is applied to it. This charge induces an electric field which creates a potential difference between the surface of the electrode and the electrolyte, which creates a separation between the positively charged anode and the negatively charged cathode. As current passes through the capacitor, the charge starts to dissipate, creating a capacitive reactance (known as its capacitance). This reactance acts as an impedance, which reduces the amount of current passing through the capacitor.

The ALS70A134KE025 has been designed for use in a variety of audio/video applications, including those with high power amplifiers and studio monitors. It is a general-purpose capacitor with a long lifespan and excellent performance in high frequencies. Its high temperature dielectric ensures its stability in high temperatures, while its low impedance helps to reduce the current pass through it. The self-healing feature also helps it to provide superior protection from shocks and vibrations, making it an ideal choice for many electronic applications.
