A brief overview to the different types of electrolytic capacitors

A BRIEF OVERVIEW TO THE DIFFERENT TYPES OF ELECTROLYTIC CAPACITORS Polarized capacitors whose anode is precisely made of a particular metal on that an insulating oxide layer effectively formed by anodization are known as the electrolytic capacitor. It is a type of electrical reservoir that systematically stores and releases electric energy.

Amplifiers, computers, radios, laptops, and televisions are some of the electronic devices in the production of which these electrolytic capacitors are used.

Aluminum, tantalum and niobium electrolytic capacitors are three different types of capacitors that are used in various commercial applications. This article discusses different types of electrolytic capacitors used in different industrial applications.

1. Aluminum electrolytic capacitor Usually called as an electrolytic capacitor, the anode of this capacitor consists of pure aluminum foil and an etched surface. This etched surface is basically covered with a uniformly thin barrier layer of insulating aluminum oxide. Designed in accordance with the international standards, it is precisely used for the stronger

applications and the power supply filters. This capacitor is not very expensive and has a descent tolerate the rate of 20%.

One of the major issues of this capacitor is that it is present only in the liquid state. If the capacitor is connected in a wrong manner, the electronic capacitors can even explode. Apart from being dry and prevent the capacitor from working, the liquid from the capacitor can also leak and immediately destroys and damage the rest of the components. Other problems with such batteries are that they do not resist to high temperature and don’t have a long lifespan.

2. Tantalum capacitor It is a polarized capacitor who anode electrode is made of tantalum. Tantalum is a very thin insulating oxide layer formed and it acts as the dielectric of the capacitor. It is a type of electrolytic capacitor is ideal for industrial applications that need large capacitance value in a very tiny space. It is important to understand that these types of capacitors are very expensive as compared to aluminum electrolytic capacitors, due to the cost of tantalum ore.

3. Niobium capacitor It is available as SMD chip capacitor and was developed in the United States as well as in the Soviet Union in the 1960s. This type of capacitor is very popular due to its lower cost, thermal stability and better availability of niobium compared with tantalum.
