WEET WCB Series Radial MLCC Capacitors(Multilayer Ceramic Capacitors) MONO Caps Cross Reference and How to ready MLCC Code Meaning

The capacity unit of capacitance is: (F), (uF), (pF). Generally we don't use it as a unit, because it's too big. 
The conversion relationship between units is: 1F = 1000000uF, 1uF = 1000000pF. In use, unit: NF is often seen. 1uF=1000nF 1nF=1000pF

If the capacitance is directly marked as 0.47, it means the capacity is 47uF and the capacitance withstand voltage is 25V. 
The mathematical counting method is adopted: the standard value is 104, and the capacity is 10x100000pF = 0.1uF. If the standard value is 473, it is 47x1000pF = 0.047uF. (the following 4 and 3 are the power of 10). Another example: 332 = 33x100pF= 3300pF.
Therefore, we can identify the capacitance of Dushi capacitor 104 according to the identification method. 
The identity 104 represents a capacity size of 0.1uF.

WEET Introduce Aluminum Electrolytic Capacitors Obvious Core Characteristics in Structure

WEE Technology Company Limited - WEE are Capacitors Specialist

The core of aluminum electrolytic capacitor is made of four layers of anode aluminum foil, electrolytic paper, cathode aluminum foil, electrolytic paper, etc. after the core contains electrolyte, it is sealed with aluminum shell and rubber cover to form an electrolytic capacitor. Compared with other types of capacitors, aluminum electrolytic capacitors have the following obvious characteristics in structure:

 (1) The working medium of aluminum electrolytic capacitor is to form a very thin layer of aluminum oxide (Al2O3) on the surface of aluminum foil by anodizing. The oxide medium layer and the anode of the capacitor are combined into a complete system, and they are interdependent and cannot be independent of each other. As we usually say, the electrode and dielectric of the capacitor are independent of each other.
 (2) The anode of aluminum electrolytic capacitor is the aluminum foil with Al2O3 dielectric layer on its surface. The cathode is not the negative foil we used to think, but the electrolyte of capacitor.
 (3) Negative foil plays the role of electrical lead-out in electrolytic capacitor, because the electrolyte as cathode of electrolytic capacitor can not be directly connected with the external circuit, it must form an electrical path through another metal electrode and other parts of the circuit.
 (4) The anode aluminum foil and cathode aluminum foil of aluminum electrolytic capacitor are usually corrosion aluminum foil. The actual surface area is much larger than its apparent surface area, which is also a reason why aluminum electrolytic capacitor usually has large capacitance. Due to the use of aluminum foil with many micro etched holes, liquid electrolyte is usually needed to make more effective use of its actual electrode area. 
 (5) As the dielectric oxide film of aluminum electrolytic capacitor is obtained by anodizing, and its thickness is directly proportional to the voltage applied by anodizing, therefore, in principle, the thickness of dielectric layer of aluminum electrolytic capacitor can be accurately controlled as a technical reference.

WEET Structure Features of WEET Micro SMD Ecap Chip and Solid Chip Aluminum Electrolytic Capacitor

WEE Technology Company Limited - WEE are Capacitors Specialist





WEET Micro Chip Aluminum Electrolytic Capacitors are Divided into Two types: Liquid and Solid(Polymer Capacitors)

Generally, the ink color of the surface is different. All imported ink, not easy to fade and fall off. The lettering of the electrolytic capacitor of the liquid chip is black, and that of the electrolytic capacitor of the WEET solid chip polymer capacitor is red and blue.

WEET Structure Features of WEET Micro SMD Ecap Chip and Solid Chip Aluminum Electrolytic Capacitor:

The full name of solid-state capacitor: solid aluminum electrolytic capacitor. The biggest difference between them is that they use different dielectric materials. The dielectric material of liquid aluminum capacitor is electrolyte, while the dielectric material of solid capacitance is conductive polymer.

As the solid-state capacitor uses conductive polymer product as the dielectric material, the material will not interact with alumina and will not explode after being electrified; at the same time, it is a solid-state product, so there will be no burst due to thermal expansion. Solid state capacitor has the advantages of environmental protection, low impedance, high and low temperature stability, high ripple resistance and high reliability. It is the highest level product in the current electrolytic capacitor products. As the solid-state capacitance is far superior to the liquid aluminum capacitance, and the solid-state capacitance has a temperature resistance of 260 degrees, good conductivity, frequency characteristics and service life. It is suitable for low voltage and high current applications, mainly used in digital products such as thin DVD, projector and industrial computer, etc., and also widely used in computer board products in recent years. In fact, the chip capacitor is essentially the same as the lead plug-in electrolytic capacitor, and the difference between them is only in the packaging or welding process.

No matter the installation process of plug-in or chip type, the capacitor itself is upright on PCB. The fundamental difference is that the capacitor installed by SMT chip process has a black rubber base. The advantage of SMT is mainly in production. It has high automation and precision. It is not easy to be damaged as plug-in type in transportation. Due to the low cost of machinery and expensive labor in European and American factories, most of them tend to SMT chip manufacturing. However, the labor of domestic factories is cheaper, so manufacturers prefer to use plug-in installation.

WEET Engineers Analyze the Advantages and Disadvantages of Super Capacitor-Coin, Radial, Lug, Screw

WEE Technology Company Limited - WEE are Capacitors Specialist

WEET Engineers would like to share the advantages of super capacitor: 

1. Capacitance up to Faraday level in a very small volume;
2. There is no need for special charging circuit and control discharge circuit;
3. Compared with battery, overcharge and over discharge have no negative effect on battery life;
4. From the perspective of environmental protection, it is a green energy;
5. The super capacitor can be welded, so there is no problem like the battery contact is not firm;

WEET Engineers also are aware of some disadvantages of super capacitor:
1. Electrolyte leakage will be caused by improper use;
2. Compared with aluminum electrolytic capacitor, it has larger internal resistance, so it can not be used in AC circuit;
For the selection of super capacitor, power requirement, discharge time and system voltage change play a decisive role. The output voltage drop of the super capacitor is composed of two parts, one is the energy released by the super capacitor, the other is caused by the internal resistance of the super capacitor. In the very fast pulse, the internal resistance part is the main part, on the contrary, in the long-time discharge, the capacitive part is the main part.
