The Complete RS-485 Profibus EMI & ESD Solution

Ready to implement!

The RS-485 EMC and ESD solution can be easily integrated into designs. We have prepared a design bag (829 485) containing the necessary parts to implement a filter for RS-485 Profibus applications. Additionally, PCB layout files (Gerber) can be found below with the following download-link.
