I am attempting to resurrect a couple of Zyxel network swtiches.
Quite simple devices, but they litterally vaned over a week or two, and then stopped working entirely.
Only the power light was on - nothing else happening.
Opening one revealed that there isn't much in there but a couple of chips, and a PSU board.,
The most common suspect component in seemingly power-related failures is the electrolytic capacitor, with the tell-tale bulging of the cap.
And sure enough, the PSU board has a few capacitrors, one of which is bulging.
So the question is: What to replace the cap(s) with?
The specifications on the side of the componentea er 10V 1000 uF.
There seems to be 20 different variants on Mouser that matches these specs.
The parameters that differentiates do not make much sense to me.
It seems to be a question about ripple currents and ESRs
As I am buying just a few, they're more or less the same price to me.
So which one's do I buy?
