jb Configuration of Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, usually simply called an electrolytic capacitor (e-cap), is a capacitorwhose anode (+) consists of pure aluminum foil with an etched surface, covered with a uniformly very thin barrier layer of insulating aluminum oxide, which operates as a dielectric. 

The electrolyte, which covers the rough surface of the oxide layer, operates as the second electrode, the cathode (-). 

E-caps have the largest capacitance values per unit volume compared to the two other main conventional capacitor families, ceramic and plastic film capacitors, but articulately smaller capacitance than similar sized supercapacitors.

Come to us jb Capacitors, a professional manufacturer for film capacitors, and aluminum electrolytic capacitors.

let us provide you the most professional support on technical side, marketing side.

jb Works to Achieve a " Zero Tolerance" for Quality Defects

As a marketing manager in jb capacitors for 6 years, I have witnessed the development of our company in the past years.
The biggest success in year 2015 is that we achieved a " Zero Tolerance" for Quality Defects.

This impressive result cannot be accomplished without jb hard working members, especially Quality and Engineer Departments.
Besides this, we also provide technical assistance to all of our jb capacitors customers. Our expertise are highly praised by customers.
We are not only selling products, we are bringing you satisfying user experience and quality assurance.

In year 2016, we will pursue higher standard both in quality and service. We are just your best choice.

jb Tells You What are Electrolytic Capacitors?

An electrolytic capacitor is a type of capacitor that uses an electrolyte to achieve a larger capacitance than other capacitor types. An electrolyte is a liquid or gel containing a high concentration of ions. 
Almost all electrolytic capacitors are polarized, which means that the voltage on the positive terminal must always be greater than the voltage on the negative terminal. 
The benefit of large capacitance in electrolytic capacitors comes with several drawbacks as well. 
Among these drawbacks are large leakage currents, value tolerances, equivalent series resistance and a limited lifetime. 

Electrolytic capacitors can be either wet-electrolyte or solid polymer. They are commonly made of tantalum or aluminum, although other materials may be used. 
Super capacitors are a special subtype of electrolytic capacitors, also called double-layer electrolytic capacitors, with capacitances of hundreds and thousands of farads.  

This article will be based on aluminum electrolytic capacitors. These have a typical capacitance between 1µF to 47µF and an operating voltage of up to a few hundred volts DC. 
Aluminum electrolytic capacitors are found in many applications such as power supplies, computer motherboards and many domestic appliances. Since they are polarized, they may be used only in DC circuits.
