Global authorized distributor
LOGO
A leading global independent distributor with cost-saving and reliable supply chain. Since 1999, we have been consistently committed to helping customers quickly and accurately find obsolete, discontinued, and hard-to-find parts, as well as obtaining genuine common parts at competitive prices. We are well aware of the difficulty of procuring obsolete electronic components. Procurement personnel often spend up to 60% of the procurement time, which is twice as much as finding regular components. In view of this, Telisemi continuously optimizes its inventory and global supplier network to shorten your procurement cycle, reduce transaction costs, and provide high-quality electronic components at highly competitive prices.
