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.

WEE Technology Company Limited - WEE are Capacitors Specialist
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.

WEET Three Types of Audio Capacitors: Pure Aluminum Foil , Pure Copper Foil and Metallized film caps
WEE Technology Company Limited - WEE are Capacitors Specialist
Plastic film capacitors can be divided into two types according to the manufacturing process of their electrodes
WEET Film / foil capacitor
Metal foil film capacitor, a plastic layer of metal foil, usually aluminum foil, is directly added to the plastic film as the electrode; this process is relatively simple, and the electrode is easy to lead out, which can be used in high current occasions.
WEET Metallized film capacitor
Metallized film capacitor, through vacuum deposited process, directly forms a very thin metal surface on the surface of plastic film as an electrode; because the electrode thickness is very thin, it can be wound into a larger capacitance capacitor; but because of the thin electrode thickness, it is only suitable for small current occasions.

WEET WMH 100VDC 10.0uF +/-3% Pure Aluminum Foil Capacitor Reviews from USA Customer
WEET 10uF 100V WMH Aluminum Foil and Film Audio Capacitor Cross is a worthy capacitor to replace the capacitors of the speaker corssover, it produces the clear sound of the high range and the smooth midrange. I have not replaced the low-bass part yet, so I cannot evaluate. With the same price segment, WMH capacitors have no competition. I think that if WEET makes copper foil film capacitors with capacities 630V and 100V, it weill be very sucessful and can compete with the capactiors of Europe and America. I am using Janten Alumen Z cap Capacitors, but I perfer the sound quality of WEET WMH Capacitors

WEET tell you how to understand the inner and outer foil of WMH 100V 200V MKP Foil Capacitor Also Called Foil and Film Condensatoren.
Firstly, we can use an Oscilloscope to test each of the leads, and you will see different waves on the Oscilloscope, please read below article for detailed reference.
http://www.jimmyauw.com/2010/04/24/observing-inner-and-outer-foil-of-some-popular-capacitors/
At the same time, we can refer to below article to understand why you need to know outside of the foil.
http://www.aikenamps.com/index.php/where-to-connect-the-outside-foil-on-capacitors
Finally, some factories will mark a line at the outer foil side, WEET can do the same, if customer request for it.

If you want to know how our WEET WMH Pure Aluminium Foil capacitor sound, we suggest you to read the reveiws of Cicada and Alumen_Z-Cap foil and film capacitors.
Our WMH is cross reference to both of them.
Cicada Pure Aluminium Foil 100VDC - 3% tolerance
Technical specifications: Film and foil type MKP from Taiwan.
Sound: The Cicada Pure Aluminium Foil capacitor is similar in character to the Mundorf Supreme in that it has a slight top-end high-lighting except the Cicada lacks the fluidity and smoothness of the Mundorf. Compared to rich and harmonically natural capacitors like Jupiter BeesWax and the Obbligato Aluminium type, the Cicada Pure Aluminium Foil sounds a little rough and technical. After a very long burn-in time they did smooth a lot but they still maintained a sort of "hifi" sound. They are very accurate and good at retrieving detail. They put an emphasis on the leading edge of the note and have nice dynamic snap that can sound exciting on some recordings or types of music. But for me ultimately they could do with a bit more natural harmonic richness and fluidity to be able to shine in all situations.
Verdict: 9+

What is the difference between 100V capacitor and 200V capacitor (used in frequency divider)
There should be no difference. The capacitance in the divider is basically about capacity
The same specifications, high voltage withstand, large volume, good insulation performance.
When using, if the conditions permit, choose the capacitor with high withstand voltage as far as possible.
What's the difference between 50V and 200V Loudspeaker Capacitor ?
They are different in withstand voltage. In theory, 100V capacitor is higher than 50V power supply. The general use allowance is 80-90%
Therefore, the power supply with 100V capacitor may be more than 80V
Using 50V may be about 40-45V

Capacitor is the simplest frequency division filter in car audio.
What is the function of WEET Audio capacitors? We have learned from high school that one of the functions of capacitors is to pass high frequency resistance to low frequency.
That is to say, let the high-frequency signal go to the high-frequency loudspeaker, and filter out the low-frequency signal.
There are two benefits to this:
One is to reduce the distortion of loudspeaker output. Because the frequency response of the tweeter determines that it is only effective for high-frequency signals, but not for low-frequency signals.
If there is no such filter capacitor, the low-frequency signals will be sent to the high-frequency speakers, and the high-frequency speakers will produce distortion to the low-frequency signals.
The second is power distribution. Generally speaking, the treble horn is smaller and can not bear more power, while most of the power of audio signal is at low frequency (the vibration amplitude is large at low frequency).
Without this filter capacitor, all the signals go into the high pitched loudspeaker, which may not be able to bear and burn out.
The capacitors have numbers of kinds, such as MKP, MKS, MKT, MKC and PET, but MKP is the best,
The temperature intensity of MKP is higher than that of MKS, but its temperature stability is slightly worse than that of MKS.
The biggest disadvantage of MKS is poor heat resistance, the limit is only 75 ℃, while MKP is 100 ℃.
