Many ICs in China are owned by foreign capital, or they have set up factories in China to change their names, and there are many miscellaneous brands. Domestic products are all small chips, and the process is relatively simple, but the cost of producing these in Europe and America is high.
Capacitors also have some contacts, mainly of the best quality in Japan, such as NIPPON, NICHICON, RUBYCON, CHEMICON, etc. Asia has cheap labor and some technologies, so there are many discrete components, and the European and American markets are small.
Because of the limited professional scope, I think so much. Typing is very hard. If you need more information, you can search for it yourself. I hope it helps you.
