Electrostatic sensitive devices

Definition
All electronic modules are equipped with highly integrated circuits or components.
Due to their design, these electronic components are highly sensitive to
overvoltage and thus to the discharge of static electricity.
These Electrostatic Sensitive Devices/modules are commonly referred to by the
acronym ESD. This is also the international abbreviation for such devices.
ESD modules are identified by the following symbol:
Fig. B-1
Caution
Modules that are sensitive to electrostatic discharge can be destroyed by voltages
well below those that can be perceived by human beings. Such voltages occur
if you touch a component or electrical connectors of a module without first
discharging the static from your body. The damaged caused on a module by
an overvoltage is not usually recognized immediately, but only becomes evident
after a longer period of operation.
