WEET WEB 2000H 105℃ Switching Power Supplies for Audio Application Snap in Aluminum Electrolytic Cap

WEE Technology Company Limited - WEE are Capacitors Specialist

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.

Application:Switching power supplies for audio applications

WEET WCD SMD MLCC Ceramic Capacitor Stock Offer and 1 Week Delivery Time

WEE Technology Company Limited - WEE are Capacitors Specialist

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

WEET Reveals the Main Difference of Pure Copper Foil Film Cap and Copper Plated Film Audio Cap

WEE Technology Company Limited - WEE are Capacitors Specialist

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.

WEET Analyze the Difference Between Pure Aluminum Foil and Silver Plated Foil Film Audio Capacitor

WEE Technology Company Limited - WEE are Capacitors Specialist

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.

Here we would like to introduce the best welcoming audio capacitor WME series to all of the audiophilers.

https://www.musicaps.com/product/WEET-WME-Premium-Music-Capacitors-Crossover-HIFI-Audio-Application-Polypropylene-Film-Capacitor.html

Overview:

WEET WME MKP metallized polypropylene capacitors your standard choice for all of your loudspeaker projects! This high-quality Premium Audio film capacitor provide perfect sound quality.

Product Description:

WEET WME axial metallized polypropylene film capacitor is made of vacuum aluminum plated polypropylene film as the combination of dielectric and electrode. The electrode is led out by tinned copper wire and filled with 94V-0 epoxy resin. Capacitance range from 0.1uF~100uF, rated voltage is 400V.DC. Well, after plenty of burn-in time (that they need to open-up) they deliver a wide and open sound stage. Nice and neutral, WEET WME Premium sounds quite organized when compared with other standard MKP's in this price range. Like all basic MKP's they can get a bit muddled when complex programme material is fed to them but they do have a certain tidiness to them which makes them go further before that sets in. The WME Premium is reasonably well balanced and neutral and in a positive way nothing sticks out. This works especially well on recordings of jazz-trio's or other small ensembles making it easier to pick out the details. The Clarity Cap SA and ESA will give you more image depth and richer harmonic overtones and the Mundorf EVO Oil will give you sharper leading edges to notes but it must be stated that those capacitors are in a higher price bracket. It is just to give you an idea in what sound quality range we are looking at here.
