Users should check for and obtain the latest relevant information and verify that such information is current and complete before placing orders for Bourns 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.

9 The characteristics and parameters of a Bourns product also can and do vary in different applications and actual performance may vary over time. Users should always verify the actual performance of the Bourns product in their specific 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 differences between laboratory and real world Bourns has explicitly designated an individual Bourns product as meeting the requirements of a particular industry standard ( , ISO/TS 16949) or a particular qualification ( , 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 qualification.

10 Users of Bourns products are responsible for ensuring compliance with safety-related requirements and standards applicable to their devices or products are not recommended, authorized or intended for use in nuclear, lifesaving, life-critical or life-sustaining ap-plications, 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 might not be safe and thus is at the user s sole risk. Life-critical applications include devices identified by the Food and Drug Administration as Class III devices and generally equivalent classifications outside of the United expressly identifies those Bourns standard products that are suitable for use in automotive applications on such products data sheets in the section entitled Applications.
