These recommendations for external components are only providing a basic protection. Depending on the

module design and the EMC speciation requirements different configurations can be needed.

The pressure sensor side facing the PCB shall be exposed only to clean dry air, it should be protected against

excessive moisture or any source of corrosion in the application.
