gold capacitors contain no gold

Hi sec!



I thought gold caps achieved their remarkable capacity through the use of thin gold foil but it turned out they rather use activated charcoal with electrolyte. Why are they called gold caps then? Are there capacitors utilizing gold foil?



First I thought the long run of gold foil was responsible for the high internal resistance and thought they could make a connection every few turns.

kind of reminds me of monster speaker wire.

If you want gold in your caps (or any other resistive foil more expensive than aluminum), you'll have to check out Audiophool products. $20 for a

0.22uF film cap, anyone? Hand wound so you *know* it's solid!
