The best capacitors in the world are manufactured by Vishay.
https://www.vishay.com They’re originally a German company but I think their headquarters is now in Belgium for tax reasons. Technically they’re a US corporation so that they can trade in the NYSE. They manufacture their product in Europe and Israel. Interesting company that is really dedicated to its products. They sell through distributors so you should be able to call any electronics warehouse and get what you need. They’re an old client of mine.
