what about kemet caps guys? i have to change few amps swichmode primary capacitors and my supplier found for me that brand high temp and low esr and its gonna be expensive.thanks for any info .

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?

my supplier says that series he offer me is low impedance.today i ask for series number just to be sure what i by.

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.

i think we are talking about the big snap-in / threaded caps

**PeteS in CA** · 03-31-2021, 11:06 AM

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.

**clearchris** · 03-31-2021, 01:14 PM

They seem to have plants all over EU, mexico and asia.

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.

I’m not an expert whatsoever, but I think that Kemet’s impedance electrolytics is not exactly small. Far from it.

OK guys the caps is all ready instaled 22 pieces KEMET PEH532.i think from specs its better than the old ones from daewoo FHT series.
