Aluminum Electrolytic Capacitors

MAL215097701E3 application field and working principle

Aluminum electrolytic capacitors, also known as electrochemical capacitors, are renowned for their long lifetime, low cost, large capacitance, and high voltage capabilities. There are two kinds of electrolytic capacitors on the market today—tantalum and aluminum electrolytic capacitors. Of the two, tantalum electrolytic capacitors usually provide higher capacitance and more features for a given size, while aluminum electrolytic capacitors tend to possess superior capacitance. As such, they are extensively used in power supplies, ripple filters, signal coupling, and snubber circuits. As the most common type of electrolytic capacitors, aluminum electrolytic capacitors are frequently adopted in many applications. In particular, the MAL215097701E3 aluminum electrolytic capacitor is a popular product.

The MAL215097701E3 aluminum electrolytic capacitor is a product of Roederstein, a well-known multinational capacitor manufacturer. It fits the EIA3220 type S case with a metalized end-cap, providing excellent properties and reliability. This capacitor has low dissipation factor and large ripple current capabilities. It offers outstanding electrical characteristics like self-healing properties, as well as its low impedance values, longer service life, and superior electrical strength.

An aluminum electrolytic capacitor is a polarized capacitor whose anode electrode is made of aluminum foil with an etched surface covered with a layer of oxide which acts as the dielectric. The cathode electrode is usually a solid metal layer formed on the oxide layer. The oxide layer acts as a weak electrolyte to allow current flow between the aluminum and the cathode. This capacitor works on mechanisms of ionic migration within the oxide layer and electrochemical reactions. When a positive direct voltage is applied across the capacitor, ions from the electrolyte migrate to the anode, forming a positively charged layer which regenerates the oxide
