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.
