Panasonic is one of the most well known manufacturers of capacitors in the modern age, from film to electrolytics. Panasonic has a few premium lines, such as their TUF series of electrolytics (I’ll be selling some of those soon) and others, such as their Pureism line. Below I have included a variety of Panasonic Catalogs, whitepapers, data sheets and patents.
Looking for something in particular that you can’t find? Contact me and I’ll see if I can help you run it down!
