if you mean the black ones with gold print - they are good.
but only on the inputs to switching supplies - i dont know about the outputs.
unless you have the part number/series so i can look them up.

Kemet has low impedance electrolytics?

I use kemet low impedence when I can't get nichicon or if the shape is more suitable. Haven't had any problems. I consider them pretty much on par with the top tier brands, but I'm not a pro.

Kemet electrolytics and polymers are low-tier Chinese products and should be avoided.

Their polymer caps are priced very competitively - but there's a reason for that. They are not on par with Japanese parts.

If you want Chinese/Taiwanese polymers, save your money and buy Apaq from LCSC.

Kemet's lytics, https://ec.kemet.com/aluminum/ , seem to be made in the EU, and the part numbers are reminiscent of Rifa's part numbering system for lytics. They don't have the low impedance low voltage parts I mistakenly had in mind.

The real problem with these types of issues (changing the amps) is not only the fact that it tend to be a little bit tricky to solve but also that the solution is always quite expensive.

Iím not an expert whatsoever, but I think that Kemetís impedance electrolytics is not exactly small. Far from it.
