WEET Conductive Polymer Aluminum Solid Electrolytic Capacitors with Chip SMD type and Radial Lead type. Due to different characteristics, Polymer Aluminum Solid Electrolytic Capacitors can be divided to Standard, Ultra-low ESR, Higher Capacitance, Long Life Assurance, High Voltage/Long Life Assurance, High Voltage/High Reliability series. Aluminum polymer electrolytic capacitors are the latest evolutionary step in improving the properties of aluminum electrolytic capacitors to make them more like a film capacitor.

Surface mount SMD type and Radial lead Polymer capacitors are produced in a similar production process to standard aluminum electrolytic capacitors(E-Cap). The main difference is the liquid electrolyte being replaced by a solid conductive polymer, usually soild conductive polymer is more stable in most applicatinos.

WEET Conductive Polymer Aluminum Solid Electrolytic Capacitors are widely used in various applications, which applicable to DC/DC converters and AC/DC converters, communication power supply, set-top boxes, router, TV, voltage regulator, mobile phone adapter (mobile phone charger), computer motherboard, graphics card, power supplies, CPU’s, Decoupling circuits and LCD Monitors.

WEET aluminum solid capacitor with high conductive polymer, which acquires low Equivalent Series Resistance (ESR), excellent noise reduction capability and frequency characteristics.

What is an audio film capacitor? Acoustic audio film capacitors are made of metalized polypropylene film, which works as the dielectric / electrode winding. The lead is made of tinned copper clad steel wire, the side is wrapped with polyester tape, and the ends are filled with epoxy resin. The performance is very outstanding, the self-healing performance is outstanding, and the high frequency loss is low.

A film capacitor is a capacitor in which a plastic film such as polyethylene, polypropylene, polystyrene, or polycarbonate is stacked from both ends and wound into a cylindrical shape. Its structure is the same as paper dielectric capacitor, and the medium is polyester or polystyrene. Polyester film capacitors have high dielectric constant, small volume, large capacity, and good stability. It is suitable for bypass electrical capacitance. Polystyrene film capacitors have low dielectric loss and high insulation resistance, but have large temperature coefficients and can be used in high-frequency circuits.

The high-frequency unit of the speaker is designed to improve high-frequency performance. Its voice coil and vibration part will be designed to be very lightweight, and the response to low-frequency signals is very low. 

Feeding a power signal with a too low frequency can easily cause damage to the vibrating parts and burn out of the voice coil . Therefore, multi-frequency speakers will use frequency dividers, so that signals of various frequency components and various frequency band units can play their due role.

The thin inner film capacitor added to the middle and high frequency unit is essentially a simple frequency divider. The thin film capacitor acts as a "high pass filter" that blocks low frequencies and allows only high frequencies to pass. 
The smaller the film capacitor capacity is, the higher the crossover point is, and the more obvious the effect of filtering low-frequency components.
This simple crossover is usually a two-way speaker, and its mid-low frequency unit feeds a full-band signal (but the mid-low frequency unit's response to high frequencies is also very low, so it will not play too much High-frequency sound capacity), the high-frequency unit feeds in a high-pass filtered high-frequency signal. Because part of the signal is filtered out, the speaker with the crossover will have a lower sound than the full-band signal, so the sound will be smaller after the audio film capacitor is added.

Now we introduce several fine film capacitors in the audio circle:

WIMA capacitor

ERO capacitor

Siemens capacitors

Philips capacitors

Rifa capacitor

Wonder capacitor

WEET capacitor

jb Capacitors

Relcap capacitor

Solen capacitor

MIT capacitor

A great audio sound system can be a wonderful thing - listening to dramatic bass drops and amazing highs can send a thrill even down the most jaded audiophile. The world of audio equipment isn't short on different things to maximize this experience either - with all sorts of speakers, tweeters, equalizers, crossovers, among many others. Regardless of what you have or want to be installed, your system won't do much unless it has the best car audio capacitor for you. These devices may be small but can improve sound quality by giving your rig the power it needs.

Audyn True Copper Cap 0.22uF 630V Copper Foil Capacitor, the sound complete different, very easy can tell so clear and get Rich mid sound too. Chinese Fuat a-cap 0.1uF 630V pure copper tube non-magnetic audio capacitor, WEET copper leadout, premium polypropylene film,  made in China, brand new quality, Super high cost performance. very smooth and clean sound, quality Compare to Jensen copper foil capacitor, the Fuat a-cap middle frequency is thicker.

In a certain range, theoretically, the larger the better, but when the performance of some components reaches the limit, if the capacitor size or capacitance is too large, it is a waste, that is to say, a waste of resources.

1: It is used in the power filter. The larger the theoretical DC voltage is more "clean", the signal output by the power amplifier is less interfered, and the sound quality is more high fidelity

2: And because the voltage on the capacitor can't be changed suddenly, when the power amplifier outputs high power at an instant (for example, there is a large subwoofer), the power supply voltage will not be pulled down at an instant, so there will be no "powerless" phenomenon, that is, the response speed.

3: But it's too big to consider whether the transformer and rectifier can withstand the large current at the moment of starting up. It's unrealistic to have a certain degree in everything, just like some people's houses are too big to waste

All in all, enough is good, just like some people's houses are just enough, just enough is OK, like their DIY amplifiers, a lot of what they care about is the sense of achievement, the sound quality is very difficult to have a standard, what they do, it may not be so in other people's eyes.
