Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, often referred to simply as an electrolytic, is a polarized capacitor whose anode, or positive plate, consists of a layer of aluminum oxide that acts as an insulating layer for the cathode, or negative plate, of solid aluminum. This electrolytic capacitor, specifically the MAL210258102E3, is noted for its relatively low equivalent series resistance (ESR) and relatively high capacitance for its size.

Application Field

The MAL210258102E3 aluminum electrolytic capacitor is frequently used in medium-voltage applications, owing to its low ESR. Its capacitance range is typically between 10uF and 100uF, and it can withstand voltages reached up to 150VDC. Additionally, the MAL210258102E3 has extremely low leakage current and low dissipation factor, making it ideal for smoother signal transfer and for radio-frequency (RF) applications.

Working Principle

The basic working principle of an electrolytic capacitor is based on Faraday\'s Law, wherein electrical energy is converted to chemical energy and subsequently released when an electric field is applied to the layers of the capacitor. Initially, the positive plate of the capacitor consists of solid aluminum, however, when a voltage is applied, electrolytic action takes place between the aluminum and its oxide film, forming aluminum ions and oxygen ions as well as resulting in the creation of an anodic oxide layer. The anodic oxide layer serves as an insulating layer between the positive and negative plates of the capacitor.

The energy stored in the electrolytic capacitor is dependent on the thickness of the anodic oxide layer and the area of the positive plate, which is proportional to the capacitance and voltage rating, respectively. This stored energy is discharged when the applied voltage is removed. The electrolytic capacitor, MAL210258102E3, has a capacitance range of 10uF to 100uF and a voltage rating of 150VDC, and because of these characteristics, it is commonly used in medium-voltage applications.
