WEET Share The Difference of WMH WMW WMJ and WME to All of Our Customers

WEE Technology Company Limited - WEE are Capacitors Specialist


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.





WEET Share Basic Function and Main Working Principle of Plastic Film Capacitors

WEE Technology Company Limited - WEE are Capacitors Specialist

1. Structure

Plastic film capacitor is a kind of capacitor with metal foil as electrode, which is overlapped with polyethylene, polypropylene, polystyrene, polycarbonate and other plastic films from both ends, and is wound into a cylindrical structure. According to the type of plastic film, they are called poly (ethyl ester) (Mylar), polypropylene (PP), polystyrene (PS) and polycarbonate.

 2. Basic parameters

(1) Rated DC voltage: DC voltage allowed to be applied continuously in the whole temperature range.
(2) Dielectric strength: the voltage that the dielectric of a capacitor can withstand, which is higher than the test voltage.
(3) Rated AC voltage: the effective value of AC voltage that can be continuously applied when the capacitor works under AC voltage.
(4) Test voltage: the voltage applied to the capacitor during the factory type test, generally 1.5 ~ 2 times, lasting for 2 minutes or 500 hours.

3. Function

(1) The function of film capacitance is the same as that of all capacitors, which is to hold the charge.
(2) But compared with other common capacitors, thin film capacitor is a kind of excellent capacitor because of its many excellent characteristics. Its main characteristics are as follows: non polarity, high insulation impedance, excellent frequency characteristics (wide frequency response), and small dielectric loss.
(3) In this case, the short circuit caused by the short circuit of the capacitor is caused by the short circuit of the metal electrode Melting and evaporation to restore insulation, so that the capacitor again restore the role of the capacitor. That is to say, it can heal itself instantly.

 4. Working principle

The working principle of thin-film capacitor is the same as that of ordinary capacitor. It stores electric energy by storing charge on the electrode. It is usually used together with inductor to form LC oscillation circuit. The working principle of capacitor is that the charge will move under force in the electric field. When there is a medium between conductors, it will hinder the charge movement and make the charge accumulate on the conductor, resulting in the accumulation and storage of charge.

 5. Advantages

Thin film capacitor is a kind of excellent capacitor because of its many excellent characteristics. Its main characteristics are as follows: non polarity, high insulation impedance, excellent frequency characteristics (wide frequency response), and small dielectric loss. Based on the above advantages, thin film capacitors are widely used in analog circuits. Especially in the part of signal cross connection, it is necessary to use capacitors with good frequency characteristics and very low dielectric loss, so as to ensure that the signal will not have too much distortion during transmission. Thin film capacitors are widely used in household appliances, lighting, industry, photovoltaic and wind power generation, new energy vehicles and other fields because of their excellent characteristics, such as good safety, high withstand voltage (single working voltage can even reach thousands of volts), non polarity, high insulation impedance and wide frequency response.



WEET WMW Copper Foil Caps Test Views In Crossovers and Bypass Audio Applications

WEE Technology Company Limited - WEE are Capacitors Specialist

I highly recommended WEET copper foil caps. I prefer them to Duelund and have tried both. Far superior to Mundorf in every way, but most especially in the mids and micro details. The WEET copper foil cap is very linear with no part of the sound spectrum highlighted.  I find the top of the line Mundorfs a tad boosted in the highs. The Duelunds a tad bumped in the upper mids. The WEET are so smooooth!

You might want to try DIYAudio, but in the "affordable" boutique crossovers my favorites so far:
Clarity MR (now CMR)
Clarity ESA
Mundorf MKP
Mundorf Supremes
WEET WMW copper foil caps

I also like Audyn Truecopper corss to WEET WMW copper foil caps (Bypass values only)
There are two main types of quality caps: metallized, and film-and-foil. The former are cheaper, the latter better: by better, I mean smoother, more refined, more detailed.
Dielectric thickness doesn't matter very much, but metal thickness does. Just about anything thick enough to be wound up on a spool is thick enough for sonics, but a deposited conductor is a different matter.
Construction is also important. The larger the capacitance, the more the cap can suffer from inductance. MIT Multicap have a connection scheme that minimizes this. Duelund has a flat pack topology which is just about optimal.Polypropylene tends to sound pretty good, but compared to styrene, is dull. PTFE (teflon) sounds a little bright compared to styrene. Styrene is, to my mind, the most neutral of the conventional dielectrics. These are the films.For metal, the best is one which connects easily (usually solders easily). Those are silver, copper, and tin. These are the foils.

WEE Technology Company Limited - WEE are Capacitors Specialist

What is copper foil?

Copper foil is a key conductive material in lithium-ion battery and printed circuit board. Copper foil is a kind of negative electrolytic material. It is a thin and continuous metal foil deposited on the substrate of circuit board.

Characteristics of copper foil products

Electronic grade copper foil (purity above 99.7%, thickness 5um-105um) is one of the basic materials of electronic industry. With the rapid development of electronic information industry, the use of electronic grade copper foil is increasing,The products are widely used in industrial calculators, communication equipment, QA equipment, lithium-ion batteries, civil television, video recorder, CD player, copier, telephone, heating and cooling air conditioning, automotive electronic components, game machines, etc.

WEET In Audio Circuit How to Connect The Positive and Negative Electrodes of the Capacitor

WEE Technology Company Limited - WEE are Capacitors Specialist'

In audio circuit, how to connect the positive and negative electrodes of the capacitor? 
As output, the positive pole is connected to the output, and the negative pole is connected to the input. When the input is used, the negative pole is connected to the input and the positive pole is connected to the output. 
For example, the two pins and one pin of the amplifier are connected to the positive pole of the capacitor, and the negative pole is connected to the input signal and output signal respectively

Audio Note Oil Filled Mylar Capacitor. The black line marking on the capacitor’s body means the negative or input side. We can see the noise is quite big if we put the positive probe on the side which has black line marking.
Lower noise if we put on the probe on the opposite way,that is the outer foil side 

Mundorf Supreme Capacitor doesn’t have marking, so you must measure one by one to confirm.For sure, lower noise if we place the probe on the opposite way.
For WEET Copper foil capacitors, we have two ways to identify the outer foil side . Firstly, we will make a marking when winding the copper and MKP on the core. Secondly, we can  mark a line or a special symbol on the surface of the marking. By doing these two process, we will show customers, a clear way to connect the positive and negative electrodes of the capacitor to gain the best music sound.

Below is the core of our WEET copper foil capacitors with marking identification.
