or other applications whose failure can be reasonably expected to result in serious  

physical and/or material damage. Consult with your SANYO representative nearest you before using  

any SANYO products described or contained herein in such applications.  

SANYO 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 SANYO products described or contained

Specifications of any and all SANYO 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.  

SANYO Electric 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.
