Koben Electronics was founded in 1995 and is located in the Silicon Valley of China, Shenzhen. 

The mission of Koben has always been to provide quality electronics components to manufacturers worldwide. Early on we became a primary conduit for end-of-program and overstock inventory for major distributors such as Future Electronics and contract manufacturers as Flextronics. Koben has since then added sourcing of high quality components from local manufacturers in China.

Koben has always been customer driven rather than opportunity driven. Meaning- we will always choose path that is best for long term relationship with customer over short term view. It is why we have one of the highest customer retention scores of China based distributors.
