What is ESD?
All electronic modules are equipped with large-scale integrated ICs or
components. Due to their design, these electronic elements are very sensitive
to overvoltages and thus to any electrostatic discharge.
These Electrostatically Sensitive Devices are commonly referred to by the
abbreviation ESD.
Electrostatically sensitive devices are labelled with the following symbol:
!
Caution
Electrostatically sensitive devices are subject to voltages that are far below
the voltage values that can still be perceived by human beings. These
voltages are present if you touch a component or module without previously
being electrostatically discharged. In most cases, the damage caused by an
overvoltage is not immediately noticeable and results in total damage only
after a prolonged period of operation.
