Any and all NCE power products described or contained herein do not have specifications that can handle applications that
require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications
whose failure can be reasonably expected to result in serious physical and/or material damage. Consult
with your NCE power representative nearest you before using any NCE power products described or contained herein in
such applications.
NCE power assumes no responsibility for equipment failures that result from using products at values
that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters)
listed in products specifications of any and all NCE power products described or contained herein.
Specifications of any and all NCE power products described or contained herein stipulate the performance, characteristics,
and functions of the described products in the independent state, and are not guarantees of the performance, characteristics,
and functions of the described products as mounted in the customer’s products or equipment. To verify symptoms and states
that cannot be evaluated in an independent device, the customer should always evaluate and test
devices mounted in the customer’s products or equipment.
NCE power Semiconductor CO.,LTD. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could
cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or
events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe
design, redundant design, and structural design.
