[QUOTE="archive10, post: 1019125"] 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., [ATTACH]108161[/ATTACH] 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. [ATTACH]108162[/ATTACH] So the question is: What to replace the cap(s) with? The specifications on the side of the componentea er 10V 1000 uF. [ATTACH]108163[/ATTACH] [ATTACH]108164[/ATTACH] 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? :) [/QUOTE]
