    wich value this cap?

    Hi...

    i've an smd capacitor, but i don't understand how to read value...

    the code is:

    7,5 B
    3E

    anyone may help me? tks.

    Ceramic or tantalum?

      ceramic....

      i think that is 7.5 uF and 16v....

        uh...tricky.
        3E might be 1.5nF, but frankly, these numbers don't fit into any pattern I'm familiar with.
        No other markings? Anything that might indicate polarity?
        Anyone?

          no other codes... and only a stripe that indicate polarity

          maybe i think that is 16v because all other non smd tantalim capacitors, are 470uF and 16v.

            7.5ยต is no standard value for caps.
            If there's a stripe, it might be a zener diode (where 7.5 is a common value), maybe 3W.
            If it's still working, it's easy to test with a DMM.

              you are in right is a zener...
              i don't know why don't think about it...

              i've replaced it with a a non smd zener...
              ...and now the power supply of the lcd works again...

              thanks a lot
