ESD Guidelines
Definition of ESD
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 electrostatic sensitive components/modules are commonly referred to as ESD devices.
This is also the international abbreviation for such devices.
Electrostatic sensitive modules are identified by the following symbol:
NOTICE
Risk of overvoltage
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 electrostatic discharge current may lead to latent failure of a module, that is, this
damage may not be significant immediately, but in operation may cause malfunction.
