WEET WEC 5000 Hours 85C Snap in aluminum electrolytic capacitor cross to CD295 Jianghai Industrial Capacitors Miniaturized Size and Long Life
So what is WEC long life snap in E-cap applications?
In most applications, aluminum electrolytic capacitors – as poled devices – are used with a DC voltage bias of proper polarity with some superimposed AC voltage.
Meanwhile, how to distinguish general purpose grade and long life grade capacitors?
Aluminum electrolytic capacitors are generally divided into two basic reliability categories: capacitors for high-reliability applications and capacitors for general-purpose applications.
This differentiation has also been adopted in the relevant IEC standards.
In IEC publications aluminum electrolytic capacitors for high-reliability applications are identified as "Long-Life Grade" capacitors. The abbreviation( LL )is stamped on the capacitors.
Aluminum electrolytic capacitors for general applications are called "General-Purpose Grade" (GP) in IEC publications.

Electrolytic capacitor is a kind of capacitor. The metal foil is the positive electrode (aluminum or tantalum), and the oxide film (alumina or tantalum pentoxide) close to the positive electrode is the dielectric. The cathode is composed of conductive material, electrolyte (electrolyte can be liquid or solid) and other materials. Because electrolyte is the main part of the cathode, electrolytic capacitor gets its name. At the same time, the positive and negative of electrolytic capacitor should not be wrongly connected.
Aluminum electrolytic capacitors can be divided into four categories: lead aluminum electrolytic capacitor; Snap in aluminum electrolytic capacitor; Screw aluminum electrolytic capacitor; solid aluminum electrolytic capacitor.

High voltage ceramic capacitor has the function of eliminating noise and filtering, and can be used in high voltage environment.
Ceramic capacitor is a kind of capacitor which uses ceramic material as medium, coating a layer of metal film on the surface of ceramic, and then sintered at high temperature as electrode. It is usually used in high stability oscillation circuit as circuit, bypass capacitor and pad capacitor.
The chip capacitor is mainly for high frequency. The high voltage chip capacitor depends on where you use it. The typical function can eliminate high frequency interference. The advantages are as follows:
1. High stability of capacity loss with temperature and frequency
2. The special series structure is suitable for long-term high voltage operation
3. High current climbing rate and suitable for non inductive structure of high current circuit.

Leaded Ceramic disc blue epoxy reigned capacitors are usually designed and manufactured by coating a ceramic disc with silver contacts on both sides.
To achieve larger capacitance, these devices can be made from multiple or times of layers.
Ceramic disc capacitors are usually through-hole mounting components with two leads and has much advantages due to their small size.
Ceramic capacitors are majorly used in the resonant circuit in transmitter stations.
Ceramic disc capacitors are also used across brush DC motors to minimize RF noise.
To understand a capacitor with code‘103’.
As the first two digits are 10 and the 3rd digit is 3, so the multiplier factor is 1000, the total capacitance value in pF is as follows:
10*1000 = 10000 pF
Similarly, if the capacitor code is 132, the 3rd digit is 2 so the multiplier factor is 100. The capacitance value will be calculated as follows:
13*100 = 1300 pF

Metal film capacitor, structure and characteristics of several common capacitors
Capacitors are commonly used electronic components in electronic equipment. In the previous article, we understand why capacitors can be connected with alternating current and blocking direct current and many kinds of capacitors are also mentioned, but there is no detailed description of various capacitors. Next, we briefly introduce the structure and characteristics of several common capacitors for your reference.
1. Aluminum electrolytic capacitor:
It is made of aluminum cylinder as negative electrode, which is filled with liquid electrolyte and inserted with a bent aluminum strip as cathode. It also needs to be treated by DC voltage to form a layer of oxide film on the positive plate as the medium. It is characterized by large capacity, but large leakage, poor stability and positive and negative polarity. It is suitable for power filter or low frequency circuit. When using, the positive and negative pole should not be reversed.
2. Tantalum niobium electrolytic capacitor:
The anode is made of tantalum or tantalum oxide. Its characteristics are: small volume, large capacity, stable performance, long life, high insulation resistance. Good temperature performance, used in higher requirements of equipment.
3. Ceramic capacitor:
Use ceramics as the medium. Silver coating was sprayed on both sides of the ceramic substrate, and then the silver film was fired as the electrode plate. Its characteristics are: small size, good heat resistance, small loss, high insulation resistance, but small capacity, suitable for high frequency circuit. Ferroelectric ceramics are suitable for low frequency circuits because of their large capacitance, high loss and high temperature coefficient.
4. Mica capacitor:
The electrode plate is made by metal foil or spraying silver layer on mica sheet. The electrode plate is laminated with mica layer by layer, and then it is made by die casting in Bakelite powder or sealing in epoxy resin. It is characterized by small dielectric loss and large insulation resistance. Low temperature coefficient, suitable for high frequency circuit.
5. Film capacitor:
The structure is the same as that of paper capacitor, and the medium is polyester or polystyrene. Polyester film capacitor, with high dielectric constant, small volume, large capacity and good stability, is suitable for bypass capacitor. Polystyrene film capacitor, with low dielectric loss, high insulation resistance and high temperature coefficient, can be used in high frequency circuit.
6. Paper capacitor:
The electrode is made of two pieces of metal foil, sandwiched in a very thin capacitor paper, rolled into a cylindrical or flat cylindrical core, and then sealed in a metal shell or insulating material shell. It is characterized by small volume and large capacity. But the inherent inductance and loss are relatively large, suitable for low-frequency circuit.
7. Metallized paper capacitor:
The structure is basically the same as the paper capacitor. It is covered with a layer of metal film on the capacitor paper to replace the metal foil. It is small in size and large in capacitance. It is generally used in low-frequency circuits.
8. Oil impregnated paper capacitor:
it is to immerse paper capacitor in specially treated oil to enhance its withstand voltage. It is characterized by large capacitance, high voltage withstand, but large volume. In addition, in practical application, firstly, different types of capacitors should be selected according to different uses; secondly, the nominal capacity of capacitors, allowable error, withstand voltage value, leakage resistance and other technical parameters should be considered; thirdly, for electrolytic capacitors with positive and negative polarity, the positive and negative electrodes should not be connected in reverse when welding.

Today we would like to share the difference of WMH WMW WMJ and WME to all of our customers, thank you.
WMH and WMW list Metalized PP along with foil...??
---> Yes. Thank you. We call it as foil with PP dielectric insulation, Metallized polypropylene film as medium and electrode
-How are they metalized?
---> WMW Copper foil spliced to polypropylene insulation film layer by layer, WMH Aluminum foil spliced to polypropylene insulation film layer by layer.
-How does the WMJ differ from the WME besides being potted in a Copper tube?
---> Except the external layer, the structure and the PP material are the same
-How are the WMH, WMJ, and WMW terminated on the end of the winding?
---> The end of the winding machine is formed by a winding machine, because the winding machine has a soldering iron head. When it reaches the end, it will burn off the metal, which will turn into plastic. When the plastic is heated, it will be packaged together.
-Do the WMC, WME, and WMF all use the same film, Are all three made with the same welded layer, and lead?
---> Yes, they use same Polypropylene film, but WMC Polypropylene film raw material is from China mainland, WME and WMF Polypropylene film raw material is imported from overseas.
At the same time, the DF factor control standard is different too. The welded layer and lead are the same.
