Filter Bag RS-485 Profibus EMC NEW

Order Code 829485

Characteristics

  • RS-485 filter circuit with all important components
  • Prevention of negative influence on the operating behavior due to interference emissions, electrostatic discharges (ESD) and fast transients (burst)
  • Straightforward design implementation through BOM and layout files

Applications

  • RS-485 applications with 9-pin D-SUB connectors and pin assignment according to PROFIBUS definition.

PCB layout files

The RS-485 EMC and ESD solution can be easily integrated into designs. PCB layout files (Gerber) can be downloaded here.

Ready to implement

Due to the steadily growing number of applications that are based on networked communication through data lines, it is becoming increasingly importan to ensure trouble-free operation and protection of electrical systems and devices.

To avoid reduced integrity of the data transfer due to interference and to pass EMC tests, components matched to the data lines are necessary. Implementation is greatly simplified by the filter bags, which contain filter components specially selected for the respective application.
