C50M6GA *RoHS COMPLIANT VERSIONS AVAILABLE *RoHS COMPLIANT LEAD FREE LEAD FREE VERSIONS ARE RoHS COMPLIANT* 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 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 users application, or (ii) the environment of the user application itself. 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 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 the requirements of such industry standard or particular qualification. 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 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 users 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 Unit ed States. Bourns expressly identifies 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 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 might not be safe and thus is not recommended, authorized or intended and is at the users sole risk. If Bourns expressly identifies a sub-category of automotive application in the data sheet for its standard products (such as infotainment or lighting), such identification 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 identifies 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 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 might not be safe and thus is not recommended, authorized or intended and is 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 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 profits, and (ii) any and all implied warranties, including implied warranties of fitness for particular purpose, non-infringement and merchantability.
