Chengx, a clone of the Chongx capacitors, which are a poor clone of pretty much any other of a million other manufacturers. If you need to buy sub 1 uF capacitors do not ever buy electrolytics, instead buy polyester or polypropylene. Pretty much any film capacitor will be better in all respects other than size, and stay away from ceramic capacitors as well, unless you get NPO types, the standard and common X7R types have both a massive tolerance variation, plus also aregoing to change capacitance with voltage applied across them as well.
But those ones apply close to rated voltage (you can put them all in parallel to do so) via a 10k resistor, so as to limit current, and also measure leakage, and leave them powered up for 48 hours to reform, and you will see a big change, though these cheap and nasty capacitors are best tossed and replaced with decent brand name types, like Nichicon, Vishay or Matsushita, though you will pay a premium for them, but they will last a long time in service, and have good performance.
