Specifications are subject to change without notice. Users should verify actual device performance in their specific applications.
The products described herein and this document are subject to specific legal disclaimers as set forth on the last page of this document, and at
www.bourns.com/docs/legal/disclaimer.pdf
Legal Disclaimer Notice
This legal disclaimer applies to purchasers and users of Bourns
®
products manufactured by or on behalf of Bourns, Inc. and
its affiliates (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 before placing orders and should verify that
such information is current and complete.
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 a combination of the Bourns
®
product with other components in
the user’s application or due to the environment of the user application itself. Such characteristics and parameters also can
and do vary in different applications and actual performance may vary over time. Users should always verify actual performance
of the Bourns
®
product in their specific devices and applications, and make their own independent judgments about how
much additional test margin to design in to compensate for differences 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 qualification (e.g., UL listed or recognized), Bourns is not responsible for any
failure of an individual Bourns
®
product to meet requirements of such industry standard or such particular qualification. Users
of Bourns
®
products are responsible for ensuring compliance with safety-related requirements and standards applicable to
their 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 specifically approved in writing by two authorized Bourns representatives on
a case-by-case basis, use of any Bourns
®
products in such unauthorized applications is at the user’s sole risk. Life-critical
applications include devices identified by the U.S. Food and Drug Administration as Class III devices and generally equivalent
classifications outside of the United States.
Bourns
®
standard products that are designed and tested for use in automotive applications will be described on the applicable
data sheets as compliant with the applicable AEC-Q standard. Unless expressly and specifically 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 is not recommended, authorized or intended and will be at the user’s sole risk.
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
®
standard products that are designed and tested for use in aircraft or space
applications will be described on the applicable data sheets as compliant with the RTCA DO-160 standard. Unless expressly
and specifically 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 is not recommended, authorized or intended and will be 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 provisions above 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, technology or technical data may not under any circumstance be exported or
re-exported to countries subject to international sanctions or embargoes, and 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 arising out of the application or
use of any Bourns
®
standard product, (ii) any and all liability, including, without limitation, special, punitive, consequential
or incidental damages, and (iii) any and all implied warranties, including implied warranties of fitness for particular purpose,
non-infringement and merchantability.
