What brands are piezoresistors zov and stth? What is official website?

The varistor ZOV is a product of Lianshun electronic platform system. STTH is a product of ST stmicroelectronics. Knowing that the company's website is easy to find, you can do it yourself.

ZOV and CNR Shunquan Electronics are both Taiwanese enterprises, and the quality of the two companies is not good, which is relatively good in China. However, now that ZOV has been acquired by Junyao, there are fewer brands of ZOV on the market, and more are brand B piezoresistors of Junyao.

In addition, there are many fakes on the market, which should be noted.
