ESD guidelines
B.1
Electrostatic sensitive devices (ESD)
ESD components are destroyed by voltage and energy far below the limits of human perception.
Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not
electrostatically discharged. ESD components which have been subject to such voltage are
usually not recognized immediately as being defective, because the malfunction does not occur
until after a longer period of operation.

NOTICE
Electrostatic sensitive devices
Electronic modules contain components that can be damaged by electrostatic discharge as a
result of improper handling.
• You must discharge your body electrostatically immediately before touching an electronic
• Always hold the component by the plastic enclosure.
• Electronic modules should not be brought into contact with electrically insulating materials
• Always place electrostatic sensitive devices on conductive bases.
• Always store and transport electronic modules or components in ESD-safe conductive
NOTICE
Storage and transport
If you have to store or transport the component in non-conductive packaging, you must first
pack the component in ESD-safe, conductive material, e.g., conductive foam rubber, ESD bag.
The diagrams below illustrate the required ESD protective measures for electrostatic sensitive
devices.

packaging, e.g. metalized plastic or metal containers. Leave the component in its packaging
until installation.
