Compact Size SMD Package CAN/RS485/RS232 Transceiver Modules - TDx31SCANH(FD), TDx31S485(H/H-E/H-A), TDx31S232H Series

MORNSUN launched the new cost-effective and compact size transceiver modules in SMD package, TDx31SCANH(FD), TDx31S485(H/H-E/H-A), TDx31S232H Series, to assist fast signal response in industries of power grid, industrial control, and transportation(rail, automotive), etc. 

The series adopt the SMT process, which enables customers to easily achieve automated processing, and greatly reduce costs. Compared with the traditional DIP package, its board area(the dimension is 17.00x12.14x9.45mm) is reduced by nearly 40% which makes the customers’ design more flexible.


Widely used in the applications of power grid, industrial control, and transportation (rail, automotive), etc.
