6.4. Electrostatics Discharge

The module is not protected against electrostatic discharge (ESD) in general. Consequently, it is subject
to ESD handling precautions that typically apply to ESD sensitive components. Proper ESD handling and
packaging procedures must be applied throughout the processing, handling and operation of any
application that incorporates the module.
The following table shows the ESD characteristics of EM05-G.

NOTE
For a good ESD performance, the module mounting holes must be used to attach the device to the main
PCB ground closely.
