Goodmorning.
I have a curiosity: can low voltage/capacity electrolytic capacitors (e.g. 16V/47uf) last longer than high voltage / capacity ones (e.g. 63V/2200uf)?
I ask because many threads indicate a life of electrolytics that does not go beyond 15 years (it seems to me that Panasonic has written something in its documents), but I have several musical instruments bought in 1980 that work perfectly: they have inside them many small electrolytics. I tried asking an electrical engineering friend to unsolder some and measure them, and these were incredibly within spec. They are over 40 years old..
While some other devices with large electrolytics, after about 30 years showed values out of specifications ...
Is there an explanation for this?
