As far as patents or other rights of third parties are concerned, liability is only assumed for components, not for
applications, processes and circuits implemented within components or assemblies.
The information describes the type of component and shall not be considered as assured characteristics.
Terms of delivery and rights to change design reserved.
Due to technical requirements components may contain dangerous substances. For information on the types in
question please contact your nearest Siemens Office, Semiconductor Group.
Siemens AG is an approved CECC manufacturer.
Packing
Please use the recycling operators known to you. We can also help you – get in touch with your nearest sales
office. By agreement we will take packing material back, if it is sorted. You must bear the costs of transport.
For packing material that is returned to us unsorted or which we are not obliged to accept, we shall have to invoice
you for any costs incurred.
Components used in life-support devices or systems must be expressly authorized for such purpose!
Critical components1 of the Semiconductor Group of Siemens AG, may only be used in life-support devices or
systems2 with the express written approval of the Semiconductor Group of Siemens AG.
1 A critical component is a component used in a life-support device or system whose failure can reasonably be
expected to cause the failure of that life-support device or system, or to affect its safety or effectiveness of that
device or system.
2 Life support devices or systems are intended (a) to be implanted in the human body, or (b) to support and/or
maintain and sustain human life. If they fail, it is reasonable to assume that the health of the user may be en-
dangered.
