    Expected life time of components

    borisvandermeer

      Hi,

       

      How can I determine the expected life time of a component? I the expected life time is dependent of various properties like temperature. But I try to determine the expected life time of this component: QRE1113GR - FAIRCHILD SEMICONDUCTOR - OPTO CPLR, PHOTOTRANSISTOR O/P, SMD-4 | Farnell element14

       

      Questions:

       

      - What is the estimated life time of the compent (max current, 25 celsius, normal operation)

      - How can I extend the expected life time? (less current through the IR led?) What is the estimated life time of the component if I use the led on 50% current.

      - Is the life time of other reflective phototransistors the same?

      - Other information about how to determine the life time of a product.
