WEET Analyze What is the Difference Between Pure Aluminum Foil Audio Capacitors and Silver Plated Foil Audio Capacitors

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.

Please check below datasheet of WEET WMH Pure Aluminum Foil and Film Polypropylene PP Capacitors and common items stock list.
