JEDEC Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in JEITA temperature, etc.) may cause this product to decrease in the TOSHIBA 2-2K1B reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the Weight: 0.006 g (typ.) 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).
