WEET Film capacitors – the best choice for music
Generally speaking, there are two types of film capacitors, film and foil MKP Capacitors, and metallized CBB film capacitors.
Electrodes in film and foil capacitors are separate sheets of metal foil wound with sheets of dielectric metallized material .These electrode sheets (or foils) extend alternately out of each end of the capacitor roll beyond the dielectric, which provide a large mass of metal material to which the leads are attached. Film and foil designs make the best choice for audio sound reproduction.
Metallized film capacitors greatly reduce the physical size of the capacitor. Discrete foil sheets are replaced with the thin layer of 99% pure aluminum or other metals that are vapor-deposited directly upon the dielectric material. Since the dielectric material is present at each end of the capacitor along with the metal electrode material, direct attachment of the leads are not possible.
The end-terminations of metallized film capacitors are created by the application of a fine, molten-metal spray. The spray makes contact with the layers of metal electrode resulting in plate contact. As the metal spray particles stack up against the aluminum electrodes, there is a compression bond resulting in a resistance higher than the discrete metal foils. The leads are attached to this metal spray, which adds additional resistance. This means there is a complex filter robbing the true, clear sound reproduction
WEET Film capacitors are widely used in audio circuits for a wide range of applications. For the optimum performance of a crossover network, film capacitors with low dielectric absorption and equivalent series resistance are commonly used. The characteristics of film capacitors make them the number one choice for audio applications. It is common for circuit designers to use a combination of different types of capacitors.

WEET is the earlest audio crossover factory in Taiwan, now we still keep some top products manufacturing in Taiwan as well, such as foil and film capacitors.
As this kinds of capacitors need very professional workers and advanced equipment, mostly we do OEM for European brands.
For general purpose audio application MKP capacitors, we are producing them in our China mainland factory, our China factory has been there for nearly 25 years, but without much popularity as we seldom look for customers, all the customers are introduced by each other. Now we think it is a right time to promote us to overseas market, WEET is fresh, but we believe with superior quality and competitive price, we will win in the end.
If you are looking for audio capacitors, please kindly send us your inquiry, free samples are on your request. We are ready to give your our best support.

When WEET WME compared to one of my favourite low-cost capacitors, the Mundorf EVO Oil, it is evident that the WEET WME still lacks some clarity and sound a bit forward.
The Mundorf EVO Oil emphasizes the top-end a fraction anyway, so maybe that comparison is not completely fair.
But on the otherhand it does explain on which side of neutral both capacitors stand regarding the amount of top end clarity.
What the EVO Oil does do much better is reproducing spatial information.
Comparing the WEET WME with other low cost types I would say that it comes closest to the Jantzen Audio Cross Cap or Jantzen Audio Standard Z-Cap.
Comparing them to the Obbligato aluminium-foil MKP there are similarities in that they are both a little upfront sounding when compared to higher grade types,
but at least the Obbligato aluminium-foil MKP shows a more open tonal balance. Like many of these basic quality MKP's WEET WME lacks some sophistication but their overall tonal balance is reasonably neutral.
The price / quality ratio is very good. I can highly recommend this capacitor if you are looking for a nice, but not too expensive MKP.

Whether DF value is high or low depends on temperature, capacity, Bai, voltage, frequency When the capacity is the same, the higher the withstand voltage, the lower the DF value. The higher the frequency, the higher the DF value and the higher the temperature. DF value is generally not marked on the capacitor, but it will be mentioned in the specification. DF can be measured on LCR. The dispersion factor (DF) is sometimes expressed by the loss angle tan.
The general DF value for WME series 0.001, so we remark a standard value on the datasheet specification table, but the real DF will change a little which depends on the capacitance, this is why we remark each DF for each item. However overall the DF is lower than 0.001, such as there are DF 0.0005 and DF 0.0008. As we all know for audio capacitors, the lower DF values, the better result. So WEET capacitors has actually lower DF values.

WEET has two plant in producing audio capacitors. One is located in China Mainland for common products, another one is located in Taiwan for high end audio capacitors.
Most of our high end products are export to overseas market, but WEET brand is not quite well-known, the main reason is that we usually do OEM service for them.
From year 2020, we have different strategy, now we promote WEET capacitors all over the word. With same quality and better price, we have confidence that the success it not far away.

Audio circuit usually includes frequency division, filtering, bypass, coupling and other capacitors.
Most of the coupling capacitance in audio circuit is CBB capacitor, because CBB capacitor has a great impact on the improvement of sound quality.
WEET WMD CBB20 Capacitors is widely used in the fields of energy saving, sound, sound box, audio frequency, flash lamp, stage lamp and disinfection lamp
How much capacitance is the best for midrange speakers?
The selection of capacitor has a great influence on the sound playing of the midrange loudspeaker. It is not suitable to be too large or too small.
In general, the capacitance of about 10 μF can be selected according to the regular pattern.
What is the best capacitance of a loudspeaker?
Generally, the resonant frequency of the common diaphragm treble is about 1000-3000hz. Look at the inner core. If the inner core is too small and the power is not enough, use 3.3uF or 2.2uF less.
There are 20 cores in the inner core, and 4.7uF can be used.
This is just a simple discussion of power. Adjusting the capacitance also needs to do some work with the matching of the bass speaker, and also consider the phase problem of the bass and treble.
The high-frequency loudspeaker is the high-frequency loudspeaker unit in the speaker box. Its function is to replay the high-frequency signal (frequency range 1 is generally within 5KHz-10KHz) output from the frequency divider.
