Electrolytic capacitors in audio circuits


Published in issue 10/2010 on page 44

Here at Elektor, for more than 20 years we’ve held the opinion that electrolytic capacitors have the worst properties for audio signal paths, possibly with the exception of ceramic capacitors. Our dielectric of preference is plastic film, with polyester/terephtalate as a minimum. Even better are polypropylene and polystyrene versions. Of course, there are ‘ultimate’ capacitors like Teflon or silver-mica devices, but we're talking about electrolytic caps here.
