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.

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.

The main difference between CBB20 MPT axial polypropylene capacitor flat and CBB20 MKP axial polypropylene capacitor round is the shape.
Sometimes due to the PCB design, the height space is limited, so it is the right choice to choose CBB20 MPT instead of .
And when the coupling capacitor is used, the effect is good!
WEET WMD CBB20 (MPA) metallized polypropylene film capacitor (axial compression flat)
WEET WMD CBB20 (MPT) metallized polypropylene film capacitor (tube and round type)
So in the production process, we need to use hot press machine to press the round film to flat shape.
Some of the factory will add more cost on the WEET WMD CBB20 (MPA) type, but to WEET, we offer the same cost to customers.
Welcome to try WEET WMD CBB20 Yellow color capacitor, the best audio and music capacitors in China.

WEET WMC MPA MPP MKP CBB19 630VDC 2.2uF 5% Audio Amplifier Capacitor
What is the main function of capacitors in audio amplifiers?
Generally capacitors in audio amplifiers has below seveval functions:
In Biasing, they Block DC signal flow
In Biasing, they Pass AC signal flow
In Feedback, they can integrate a signal
In Filters, they can differentiate a signal
As a rule the bigger the value of capacitance the lower the frequency ( FQ ) that will pass through the cap.
If the capacitor goes to ground it diminishes ( shunts ) lower FQ signals out of the amplifier.
If the capacitor goes in series with the signal path in (pass mode) it increases the lower FQ of the amplifier.

WEET Is it Better to use 100V 2.2uF Capacitor or 250VDC/400VDC 2.2uF for High Pitch Speaker?
The answers to this question is up to the circuit , we usually suggest to use high voltage capacitor to replace lower one in most applications. But sometimes it will be exception. so you can try both and find the best one you need.
The yellow appearance capacitor, Audiophiler MKP-kondensotor 2.2uF/400VDC, is polypropylene film capacitor, which has the characteristics of small leakage, fast reaction speed and no inductance. It can be used in power supply B and filter circuit of gall machine.WEET capacitor has a wide range of sound, excellent timbre, soft and sweet tone, and good charm. It is more suitable for coupling and linking between stages, especially for output cross linking.
