Hi dear,

Can You help pls with LP5907SNX-2.5/NOPB.

Seems that the marking should be "F9"

Is there the datecode in marking?

    Hi,

    Unfortunately, I am not able to read the markings in the picture. For the DQN package, the middle line should be marked with "F9". The first and third lines are marked with a binary date code:

    _| = 1st Quarter of Year
    |_ = 2nd Quarter of Year
    _
     | = 3rd Quarter of Year
    _
    | = 4th Quarter of Year

    Are you able to type out what the markings are?

    Thanks,
    Gerard

    Hi,

    thank U a lot for answer.

    Seem that the marking is:

             _

    _ _ F9

    the first "line" is crossing the 1-pin marker

    and the second "line" is corssing "F" and it looks like "E"

    Hi Paolo,

    I apologize for making a mistake in my first post. The markings above and below F9 make up the binary year code (6). The symbol in the bottom left corner of the picture above indicates the quarter of the year (3). All together, the markings correspond to the 3rd quarter of 2016.

    Thanks,
    Gerard
