What are these capacitors? And is it blown?

    Hi,

    I have been struggling with these capacitors as I can not identify them. So far I have just got their capacitance - 105C -> 1uF +/- 0.25pF. But what about their voltage? And what would be the voltage of 0812 and 0811 code? They are from a computers PSU. 2017-04-26 16.15.34.jpg

    And is the small one blown? I would say so, but maybe its just glue?

    Thanks a lot!

    The orange brown stuff is glue.
    105°C is the temperature rating.
    0811 and 0812 are probably date codes.
    The capacitance and voltage rating are written on there somewhere.
    Have a look (photo) round the other side.

    You are right. I don't get how I missed that. And I swear I looked more than once.
    Thanks for your help!

    Sure sign of a blown electrolytic capacitor is when the top starts to bulge. These look OK. If you do replace make sure you get high quality low ESR types. ESR = Equivalent Series Resistance
