Expected Life Calculation
Expectedlifedependsonoperatingtemperatureaccordingtothefollowingformula:L=Lox2
(To-T)/10
Where:
L: Expected life
Lo: Load life at a maximum permissible operating
temperature
T: Actual operating temperature
To: Maximum permissible operating temperature
Thisformulaisapplicablebetween40°CandTo.
