legal disclaimer notice this legal disclaimer applies to purchasers and users of bourns ? products manufactured by or on behalf of bourns, inc. and its afliates (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 users application or due to the environment of the user application itself. such characteristics and parameters also can and do vary in diferent applications and actual performance may vary over time. users should always verify actual performance of the bourns ? product in their specifc devices and applications, and make their own independent judgments about how much additional test margin to design in to compensate for diferences 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 qualifcation (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 qualifcation. 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 specifcally 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 users sole risk. life-critical applications include devices identifed by the u.s. food and drug administration as class iii devices and generally equivalent classifcations 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 specifcally 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 users 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 specifcally 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 users 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 inter national 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 ?
