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.

Weight: 2.4 mg (typ.)  
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).
