pure water capacitor?!?

** If Panasonic say so.........

** Nope.

** Yep.

** The use of capitals for the initial letters in each word indicates the three words make up a * NAME * - so it is very wrong to assume they also constitute a technical description.

All is says to me is that Panasonic purify the water used in the electrolytes in their electros.

Just as ALL electro cap makers do !!!!!!!!!!

Bose once made a BIG point that all their drivers employed " helically wound voice coils " .

LOL

Cappice ???

In contrast to common plastic films such as mylar, polypropylene and such, water has a very high dielectric constant, around 80, compared to 2-5 for such typical dielectrics. (Ceramics of course reach into the thousands.) The problem is, for the same reason water has a high dielectric constant, it also tends to dissolve ions, making a conductive solution, defeating the purpose of a capacitor in the first place! Even very pure water has some resistivity, on the order of a semiconductor I suppose. (The figure "16.7 megaohms" comes to mind, but resistivity is ohms per length, not blind ohms!!)

At any rate, capacitors are a hot subject among audiophools .. sorry .. audiophiles. A good idea is to take anything said around audio, especially "high quality" audio, with several grains of salt.

Especially when they get to stuff like the "Clear, pure water" resulting in a more "transparent sound". Sheesh! ;-)
