Re: General advice on replacement of old decoupling tantalum capacitors (by new tants or alum. lytics).
Thank you all for your answers,toggle quoted messageShow quoted text
I summarize then the outcome, which I will follow.
So, Regarding substitution of tantalum capacitors, as a general advice:
1. Nothing wrong with the tantalum caps "per se", as long as one observes
at least 1/2 to 1/3 voltage derating (a practical recommendation that
hasn't been known - or followed - by Tek, back then).
2. It IS recommended to replace all power decoupling tants (i.e. connected
directly to power rails) that are not derated as per criteria above. Other
than that, it's not strictly necessary to blindly replace tantalum
capacitors (i.e. just because they're old, as they're not subject to
"dry-out" effect as their alum. counterparts).
Kindest Regards to all,
