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).
