Bourns RS-485 Port Protection

Bourns RS-485 evaluation boards are a design resource that streamlines evaluating circuit protection on RS-485 serial device ports. The Bourns RS-485EVALBOARD1 includes two Bourns® TBU® High-Speed Protectors (HSPs), two Bourns® fast-acting GDTs and two Bourns® TVS diodes. The Bourns RS-485EVALBOARD2 uses Bourns® TBU® High-Speed Protectors (HSPs), MOVs and TVS products. Both boards offer 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 smaller reduced PCB area and are manufactured using FR4 PCB with nickel gold plating on top and bottom sides.

Extremely high-speed performance
Small size requires minimal PCB area
