ESD Guidelines
What does ESD mean?
All electronic modules are equipped with large-scale integrated ICs or components. Due to
their design, these electronic elements are highly sensitive to overvoltage, and thus to any
electrostatic discharge.
The acronym ESD has become the established designation for such Electrostatic Sensitive
Devices. This is also the international abbreviation for such devices.
ESD modules are identified by the following symbol:
NOTICE
Damage caused by electrostatically charged persons
ESD devices can be destroyed by voltages well below the threshold of human perception.
These static voltages develop when you touch a component or electrical connection of a
device without having discharged your own body. The electrostatic discharge current may
lead to latent failure of a module, that is, this damage may not be apparent immediately, but
in operation may cause malfunction.
