They also make high quality polymer SMT capacitors that are used as bulk capacitors on the power distribution circuitry on laptops and other devices. In the case of polymer caps, all types are considered good for PSU usage due to their ability to withstand higher operating temperatures than their electrolytic counterparts.
When it comes to electrolytic caps, since they are hugely affected by increased temperatures caused by heat build-up at the PSU's internals (but mostly by current ripple), the caps made by Japanese manufacturers are the safest and highest-quality choice. This is also why Japanese capacitors are always preferred.
bad caps can be made in japan and good caps can be made in china just because a components was made in a certain place does not mean its automatically better than another You need to look at the manufacturer, not just the country. That being said most good electrolytic capacitors do come from Japan. "We also blind small animals with cosmetics.
Capacitors seem to be one of those things that is counterfeited a lot, so definitely want to buy from good sources like Digikey, Mouser etc. AVoid Ebay, Aliexpress, Amazon etc as you don't know what you're getting. Re: Capacitor brands? Vishay and Kemet are not "premium" grade electrolytic manufacturers.
This is also why Japanese capacitors are always preferred. However, there are two problems with using Japanese-made caps: their cost is higher and sometimes there are availability problems. Most PSU factories are located in China, so they have to import the capacitors from Japan, requiring additional time and shipping costs.
*The best capacitor is used as a reference: 100% performance rating The Chemi-Con KY capacitors have top ratings, and indeed, as you can see, their capacitance is close to the values specified by the manufacturer, while the Teapo and Elite capacitors have a significantly lower actual capacitance.

Every attempt of the test should show similar result on the display for a good capacitor. If there is no change in the resistance in the further tests, the capacitor is dead. This …
In my opinion, the fake capacitors are one of the biggest contributors to the overall failures on cheap gear (not so much HiFi, but consumer electronics in general). When it …
EVGA nor Corsair "make" the units. EVGA has many good units for sale like the GS, G2, P2, B2 and various cheap models. The NEX should be avoided as well as the G1. …
If both values are nearly identical, the capacitor is in good condition. 7. However, if there is a noticeable difference between the experimental and printed values, the capacitor is …
