jb Capacitors Tell You Difference Between Electrolytic and Ceramic Capacitor

Electrolytic VS  Ceramic Capacitor

A capacitor is an electrical component which is able to store electrical charges. Capacitors are also known as condensers. Ceramic capacitors and electrolytic capacitors are two main types of capacitors that are widely used in electrical and electronic components. The ceramic capacitor uses a thin ceramic layer as the dielectric medium whereas the electrolytic capacitor uses an ionic liquid as one of the sheets of the capacitor. In this article, we are going to discuss what electrolytic capacitor and ceramic capacitor are, their properties, and finally a comparison between electrolytic capacitor and ceramic capacitor and summarize the difference between ceramic capacitors and electrolytic capacitors.

What is a Ceramic Capacitor?

In order to understand what a ceramic capacitor is one must first understand what a capacitor is in general. Capacitors are devices that are used to store charges. Capacitors are also known as condensers. Commercially used capacitors are made of two metal foils with a dielectric medium in between them rolled into a cylinder. The capacitance is the main property of a capacitor.
The capacitance of an object is a measurement of the amount of charges that object can hold without discharging. Capacitance is a very important property in both electronics and electromagnetism. Capacitance is also defined as the ability to store energy in an electric field. For a capacitor, which is having a V voltage difference across the nodes and the maximum amount of charges that can be stored in that system is Q, the capacitance of the system is Q/V, when all are measured in SI units. The unit of the capacitance is farad (F). However, as it is inconvenient to use such a large unit, most of the capacitance values are measured in nF, pF, µF and mF ranges.
In a ceramic capacitor, a thin ceramic layer act as the dielectric medium. A ceramic capacitor has no polarity. Ceramic capacitors are classified into three main classes. Class I capacitors have better accuracy and low volumetric efficiency whereas class III capacitors have low accuracy and high volumetric efficiency.

What is an Electrolytic Capacitor?

An electrolytic capacitor is made by having an ionic liquid as one of the conducting plates of the capacitor. Most of the electrolyte capacitors are polarized. This means the voltage at the anode cannot become negative relative to the voltage applied to the cathode. If this happens, the capacitor becomes corrupted by ion exchange. Electrolytic capacitors are famous for having higher volumetric efficiency. This means a small capacitor is able to hold larger amount of charges than a ceramic capacitor of the same size.

What is the difference between Ceramic Capacitor and Electrolytic Capacitor?

• Ceramic capacitor has two metal sheets at the terminals to store charges. The electrolytic capacitor has one metal sheet and an ionic liquid as the two terminals.
• Electrolytic capacitors are capable of holding more charges per volume than ceramic ones.
• Most of the electrolyte capacitors are polarized, but ceramic capacitors are never polarized

jb Shares What is Electrolytic Capacitors And Aluminum Electrolytic Capacitors

Electrolytic Capacitors

Electrolytic capacitors differ from other capacitors. One of the plates in an electrolytic capacitor is a liquid. 
The liquid is an electrolyte (an ion bearing liquid that conducts electricity, which is what gives the electrolytic capacitor its name. 
During the manufacturing process, a thin layer of oxide builds up between the electrolyte and the plate. 
This thin layer of oxide forms the insulating dielectric. Because the plates are large and the dielectric is thin, the capacity to store electricity is larger in electrolytic capacitors than in any other type. 
This makes electrolytic capacitors the capacitor of choice when building power supplies.

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors have an aluminum plate and the dielectric is aluminum oxide. 
This type of electrolytic capacitor is inexpensive and is found in many power supplies. 
Their range in value from 1 farad down to less than a microfarad. E-caps can work voltages up to several hundred volts. 
Aluminum electrolytic capacitors can break down if they go through long periods of no power (the oxide breaks down.) 
Elco caps can be rejuvenated if connected to a power supply and a resistor--the long low current restores the oxide.
Elco caps are not suitable for working with high frequencies, and they're also used in radio frequency amplifiers or anywhere there are high currents and low frequencies.
