JEDEC
JEITA Using continuously under heavy loads (e.g. the application of TOSHIBA 1-1E1A high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the Weight: 0.004 g (typ.) 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). Note 1: Mounted on a glass epoxy board of 20 mm x 20 mm, pad dimension 4 mm x 4 mm. Note:
