RS485 Application Note

●RS-485EVALBOARD2 evaluation board serves as an aid in evaluating circuit protection on RS-485 serial device port solutions using Bourns TBU High-Speed Protectors (HSPs), MOVs and TVS products to meet the required industry standards on RS-485 port interfaces. The recommended Bourns TBU HSP device solution on RS-485EVALBOARD2, offers enhanced high-speed performance features over competing technologies, which can help the design engineer increase the surge and transient protection level on RS-485 ports and place the entire circuit protection solution into a reduced PCB area. Bourns has developed an RS-485 Evaluation Board (measuring 50mm x 25mm x 1.2mm) manufactured using FR4 PCB with nickel gold plating on the top and bottom sides.
