Products listed in this document are no antiradiation design.

The products listed in this document are designed to be used with ordinary electronic equipment or devices

(such as audio visual equipment, office-automation equipment, communications devices, electrical

appliances and electronic toys).

Should you intend to use these products with equipment or devices which require an extremely high level

of reliability and the malfunction of which would directly endanger human life (such as medical

instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel controllers

and other safety devices), please be sure to consult with our sales representative in advance.

It is our top priority to supply products with the utmost quality and reliability. However, there is always a chance

of failure due to unexpected factors. Therefore, please take into account the derating characteristics and allow

for sufficient safety features, such as extra margin, anti-flammability, and fail-safe measures when designing in

order to prevent possible accidents that may result in bodily harm or fire caused by component failure. ROHM

cannot be held responsible for any damages arising from the use of the products under conditions out of the

range of the specifications or due to non-compliance with the NOTES specified in this catalog.
