> Electrolytic Capacitors are perishable, they age even when not used.
But not that perishable. I have some old electronics, along with fully analog devices (guitar effects) and they, along with their power supplies(which get hot) still work.
> People arent surprised when servicing cars, why different expectations with modern electronics?
Because they have orders of magnitude less moving parts - if any.at all. Is it unreasonable to expect something that has one moving part to not fail after two years?
Actually, I wouldn't want a car exhibiting mechanical problems after such a short period.
- rasz 5y agoOld gear didnt depend on low ESR (simplified resistance at high frequencies). Every time you turn on a piece of electronic with linear power supply electrolytic caps will slowly reform and start working better and better with time. Modern gear is DC-DC converters all the way down. Aged cap means no supply voltage at all (doesnt turn on), or crazy ripple (crashes, produces funny sound or visible artifacts). >Actually, I wouldn't want a car exhibiting mechanical problems after such a short period. Nobody would, thats what scheduled services are for.
