Users should check for and obtain the latest relevant information and verify that such information is current and complete before placing orders for ourns products. The characteristics and parameters of a ourns 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 ourns knowledge of typical requirements in generic applications. The characteristics and parameters of a ourns product in a user application may vary from the data sheet characteristics and parameters due to (i) the combination of the ourns product with other components in the user s application, or (ii) the environment of the user application itself. The characteristics and parameters of a ourns 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 ourns 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 ourns has explicitly designated an individual ourns product as meeting the requirements of a particular industry standard (e.g., SO/TS 6949) or a particular qualification (e.g., UL listed or recognized), ourns is not responsible for any failure of an individual ourns product to meet the requirements of such industry standard or particular qualification.
