The relative relationship between the service life of electrolytic capacitor and ambient temperature. 

When the ripple current is constant (such as rated ripple current), the higher the ambient temperature, the shorter the service life of electrolytic capacitor.
If the ambient temperature is too high and exceeds the maximum rated temperature of the electrolytic capacitor, the electrolyte in the electrolytic capacitor will boil and produce overvoltage, and the pressure relief parts will produce irreversible pressure relief action, resulting in electrolyte leakage and permanent damage to the electrolytic capacitor.Therefore, the storage and service temperature of electrolytic capacitors must not exceed the rated temperature. 

On the contrary, if the working temperature is reduced, the service life of electrolytic capacitor can be greatly increased. For example, the service life of electrolytic capacitor with rated maximum temperature of 85 ℃ is 1000 hours under the ambient temperature of 85 ℃, while when the ambient temperature is reduced to 60 ℃, the service life can be extended to about 10000 ℃, and when the ambient temperature is reduced to 40 ℃, the service life can reach about 80000 hours, In actual use, it can be seen that the actual service life of electrolytic capacitor is much higher than the nominal value, which is the reason why the service temperature is lower than the maximum rated temperature.

Therefore, if conditions permit, it is a good way to reduce the ambient temperature as much as possible to prolong the service life of electrolytic capacitor. Therefore, it is usually required that electrolytic capacitor should be far away from the heat source in design.

Recently, we got a request from one PCB assembling factory that they need us to offer best replacement for Rubycon, Nichicon capacitors.
After studying his PCB layout, we found the PCB board is very tight designed. So small size and miniature diameter Snap in Aluminum Electrolytic Capacitors is needed.
Lucky, we found we have produced these capacitors before, we provide the samples within two days. How efficient it is,  right?
Now we are patiently waiting for the testing result and mass production for this customer.

We are glad to inform you that we have resume work from National holiday on Oct 8th.
Before the holiday, we got a sample request from one of our cusotmer for WFB MKP Metallized Polypropylene Film Capacitor CBB21 3.0µF ±10% 250VDC 30*22*13mmMax Pitch 27.5mm Bulk RoHS.
We thought the lead time will be longer due to holiday. However, we made out 15pcs of the samples in three days.
I am really impressed by the efficiency of our work and good disciplined of our company. 

It is a great honor to with with WEET team numbers.

Generally, the chip capacitor refers to MLCC, that is, multilayer ceramic capacitors, also known as chip capacitors or SMD capacitors. Conventional chip capacitors are divided into COG (NPO), X7R and Y5V according to materials. According to the British standard, their pin packages usually have the following 13 models: 0201, 0402, 0603, 0805, 1206, 1210, 1808, 1812, 1825, 2220, 2225, 3012 and 3035.
0201, 0402, 0603, 0805, 1206 is a chip capacitor with common package size, and the capacity range is generally 0.5pF ~ 1uF.
1210, 1808, 1812, 1825, 2220, 2225, 3012, 3035 are large-size chip capacitors with a capacity range of 1uF ~ 100uF

First of all, let us ask a question to all of the customers. Please refer to below two types of capacitors description and identity which one is Pure Copper Foil Audio Capacitors? And why?

1, Copper Foil MKP-T 2.2uF 100V OD*L 12.5*31mm, DF value 0.001

2, Copper Foil PPCT 2.2uF +/-5% 100V OD*L 23*64mm, DF value 0.0001

Well, WEET would like to answer it. No doubt, number 2 PPCT is the Pure Copper Foil Audio Capacitors. there are three reasons for it.

Firstly, PP refer to the original polypropylene insulation film, CT is the first letter of Chinese words “Chun Tong”, which means pure copper. Likewise, MKP is metallized polypropylene, T is the first letter of Chinese words “Tong”, which means copper. So MKP-T has no pure copper, but with plated copper material on the PP film surface, which is very thin and only one layer.

Secondly, as Pure Copper Foil PP Audio Capacitors have two layers, a layer of pure copper foil and a layer of PP film. So the size will be much bigger than copper plated foil MKP capacitors.

Regarding the sounding performance, Pure Copper Foil PP Audio Capacitors has much lower DF values. Lots of people want to try and hear how Pure Copper Foil PP Audio Capacitors sound, but due to high price tag, customers made hesitation.         

However, price differences are used as a proxy for differences in quality. You deserve to hear the best sound of your speaker or audio application.

If you are very active in audio forums and related business filed, you must be quite familiar with “ Foil and Film” phrase. Maybe you will see lots of products names as Aluminum foil capacitor or Silver foil capacitor. Yes, that is true to some extents.

WEET engineers would like to tell you the advantages of Pure Aluminum Foil and Film Polypropylene PP Capacitors than Silver Plated Foil metallized polypropylene Audio Capacitors

The main Dielectric for both of the above two type capacitors are Polypropylene film, but Pure Aluminum Foil are winding by a layer of Pure Aluminum foil spliced to a layer of original polypropylene insulation film. There are two layers individually. So the size and weight for Pure Aluminum Foil are bigger and heavier than Silver Plated Foil Audio Capacitors

However, for Silver Plated Foil Audio Capacitors, there is only one layer winding on the core. Electroplating the metal composed of silver on the surface of the original PP film, which can also be called as metallized silver polypropylene film. 

Regarding the sounding performance, pure foil PP capacitors has much lower DF (Dissipation factor) values than plated foil metallized polypropylene film capacitors.
