Weight: 1.5 g (typ.)
Note:
Using continuously under heavy loads (e.g. the application of high
temperature/current/voltage and the significant change in temperature, etc.)
may cause this product to decrease in the reliability significantly even if the
operating conditions (i.e. 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).
