Legal Disclaimer Notice
This legal disclaimer applies to purchasers and users of Bourns® products manufactured by or on behalf of Bourns, Inc. and
its aliates (collectively, “Bourns”).
Unless otherwise expressly indicated in writing, Bourns® products and data sheets relating thereto are subject to change
without notice. Users should check for and obtain the latest relevant information and verify that such information is current
and complete before placing orders for Bourns® products.
The characteristics and parameters of a Bourns® product set forth in its data sheet are based on laboratory conditions, and
statements regarding the suitability of products for certain types of applications are based on Bourns’ knowledge of typical
requirements in generic applications. The characteristics and parameters of a Bourns® product in a user application may vary
from the data sheet characteristics and parameters due to (i) the combination of the Bourns® product with other components
in the user’s application, or (ii) the environment of the user application itself. The characteristics and parameters of a Bourns®
product also can and do vary in dierent applications and actual performance may vary over time. Users should always verify
the actual performance of the Bourns® product in their specic devices and applications, and make their own independent
judgments regarding the amount of additional test margin to design into their device or application to compensate for
dierences between laboratory and real world conditions.
Unless Bourns has explicitly designated an individual Bourns® product as meeting the requirements of a particular industry
standard (e.g., ISO/TS 16949) or a particular qualication (e.g., UL listed or recognized), Bourns is not responsible for any
failure of an individual Bourns® product to meet the requirements of such industry standard or particular qualication. Users
of Bourns® products are responsible for ensuring compliance with safety-related requirements and standards applicable to
their devices or applications.
Bourns® products are not recommended, authorized or intended for use in nuclear, lifesaving, life-critical or life-sustaining
applications, nor in any other applications where failure or malfunction may result in personal injury, death, or severe property
or environmental damage. Unless expressly and specically approved in writing by two authorized Bourns representatives
on a case-by-case basis, use of any Bourns® products in such unauthorized applications might not be safe and thus is at
the user’s sole risk. Life-critical applications include devices identied by the U.S. Food and Drug Administration as Class III
devices and generally equivalent classications outside of the United States.
Bourns expressly identies those Bourns® standard products that are suitable for use in automotive applications on such
products’ data sheets in the section entitled “Applications.” Unless expressly and specically approved in writing by two
authorized Bourns representatives on a case-by-case basis, use of any other Bourns® standard products in an automotive
application might not be safe and thus is not recommended, authorized or intended and is at the user’s sole risk. If Bourns
expressly identies a sub-category of automotive application in the data sheet for its standard products (such as infotainment
or lighting), such identication means that Bourns has reviewed its standard product and has determined that if such Bourns®
standard product is considered for potential use in automotive applications, it should only be used in such sub-category of
automotive applications. Any reference to Bourns® standard product in the data sheet as compliant with the AEC-Q standard
or “automotive grade” does not by itself mean that Bourns has approved such product for use in an automotive application.
Bourns® standard products are not tested to comply with United States Federal Aviation Administration standards generally
or any other generally equivalent governmental organization standard applicable to products designed or manufactured for
use in aircraft or space applications. Bourns expressly identies Bourns® standard products that are suitable for use in aircraft
or space applications on such products’ data sheets in the section entitled “Applications.” Unless expressly and specically
approved in writing by two authorized Bourns representatives on a case-by-case basis, use of any other Bourns® standard
product in an aircraft or space application might not be safe and thus is not recommended, authorized or intended and is at
the user’s sole risk.
The use and level of testing applicable to Bourns® custom products shall be negotiated on a case-by-case basis by Bourns
and the user for which such Bourns® custom products are specially designed. Absent a written agreement between Bourns
and the user regarding the use and level of such testing, the above provisions applicable to Bourns® standard products shall
also apply to such Bourns® custom products.
Users shall not sell, transfer, export or re-export any Bourns® products or technology for use in activities which involve the
design, development, production, use or stockpiling of nuclear, chemical or biological weapons or missiles, nor shall they use
Bourns® products or technology in any facility which engages in activities relating to such devices. The foregoing restrictions
apply to all uses and applications that violate national or international prohibitions, including embargos or international
regulations. Further, Bourns® products and Bourns technology and technical data may not under any circumstance be
exported or re-exported to countries subject to international sanctions or embargoes. Bourns® products may not, without
prior authorization from Bourns and/or the U.S. Government, be resold, transferred, or re-exported to any party not eligible
to receive U.S. commodities, software, and technical data.
To the maximum extent permitted by applicable law, Bourns disclaims (i) any and all liability for special, punitive, consequential,
incidental or indirect damages or lost revenues or lost prots, and (ii) any and all implied warranties, including implied warranties
of tness for particular purpose, non-infringement and merchantability.
