11.1.2 ESD guideline
What ESD means
Almost all electronic modules are equipped with highly integrated components and elements
in MOS technology. Due to their their technology, these electronic components are
extremely sensitive to power surges and also to discharges of static electricity. These
components are therefore marked as follows:
•
ESD:components suceptible to ElectroStatic Discharge
• ESD: internationally recognized marking for components and modules susceptible to
electrostatic discharge
