When he says "Air is only practical for the lowest capacitances" how low do u think he means by low capacitances? serengetiplains quote: Originally posted by zBuff When he says "Air is only practical for the lowest capacitances" how low do u think he means by low capacitances? Probably in the picofarad range. Personally, I'm waiting for someone to develop a foam teflon capacitor. Dielectric constant, say, of about 1.6-1.7. Anyone feeling so inspired? Think Mupor, Porex, GoreTex ... SY Foam is not a good thing unless you want a microphone. jackinnj quote: Originally posted by zBuff http://www.audience-av.com/on_capac...ic_material.htm interesting read, explains why some ppl have found that have nude caps sounds better. When he says "Air is only practical for the lowest capacitances" how low do u think he means by low capacitances? Air variable capacitors -- like the kind used in old a.m. radios -- had a capacitance of 365pF per bank -- of course when I was growing up it was mmF, not pF.
