temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. Weight: 0.013 g (typ.) operating temperature/current/voltage, etc.) are within the absolute maximum ratings.

Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
