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 Capacitors Offer 1000H to 2000H at 105°C SMD Aluminum Electrolytic Capacitor- JCK

SMD Chip-type capacitors are soldered using a reflow method. JCK series aluminum electrolytic capacitor , operating with wide temperature range -40~+105°C is designed for surface mounting on high density circuit board in which shape to help them easier to mount to substrates subjected to the reflow method. JCK chips E-cap have achieved a capacitor with low ESR and high ripple current resistance. Now we printed the “jb” logo in the surface of JCK series aluminum electrolytic capacitor to make a difference with old one

Typical applications for JCK series aluminum electrolytic capacitors include PC motherboards, game consoles, wind power converters, and electronic car components. Especially Electronic car component applications, they have shown remarkable growth in recent years, and this will be our focus as we look at the latest trends in chip-type aluminum electrolytic capacitors.

jb Capacitors Show You What is 2000H at 85°C SMD Aluminum Electrolytic Capacitor-JCS

What is surface mount Aluminum Electrolytic Capacitor? Aluminum Electrolytic Capacitor has relatively high equivalent series resistance (ESR), which means that they generate high heat for a given current level. Aluminum Electrolytic Capacitor is low cost, have a high capacitance value and high energy density value. Energy density determines the amount of energy that may be stored in a given volume.

Aluminum Electrolytic Capacitor are polarized types with limited frequency response whose anode electrode (+) are made from a high-purity aluminum foil with an aluminum oxide thin film dielectric on its surface. SMD style electrolytic capacitors with non-solid electrolyte (vertical-chips, V-chips) have a colored filled half circle or a minus bar on the top case side visible to indicate the minus terminal side. Additionally, the insulating plate under the capacitor body uses two skewed edges to indicate that the negative terminal is on the complement position.

With V-chip type, jb JCS series capacitor are shaped to make them easier to mount to substrates subjected to the reflow method. Emboss carrier tape packing system is available for automatic insertion. Operating temperature from -40°C to +85°C, Capacitance range 0.1ufF~10000 uF are available. Leakage current (Φ4~Φ10) ≤0.01CV or 3μA, whichever is greater (after 2 minutes application of rated voltage).Leakage current (Φ12.5~Φ16) ≤0.03CV or 4μA, whichever is greater (after 1 minutes application of rated voltage)
