Oh those electrolytic SMD capacitors!!

[Wizard]

Why are these not up to good ESR levels according to my bob parker's ESR meter even new? Ditto on recent boards with these when I spot checked them.

Is it not fresh or just very inferior? Is there much better one out there?

Cheers, Wizard

Re: Oh those electrolytic SMD capacitors!!

they tend to age rather quickly.
they also have higher esr than radial lead parts of the same value.

Don`t forget that lower capacitance caps does have higher ESR then bigger ones.
