    I have run across a ceramic disc capacitor that I am clueless on the value it should have. It simply has the number 5 with a line under it and the top of the disc has a black top. Measured on a Z meter reads at 15.5pF. Anybody have a guess on this code?

    Ceramic Caps, (Usually):
    Fractional numbers refer to uF.
    Whole numbers to pF.

    5pF?

    The black line, could be the voltage rating.

    I'd say 5 pF and a Z meter with poor accuracy at those low values.

    Hi,

    Probably just shoving the capacitance of the connection wires/fingers/whatever.
    Just touching one terminal of my L/C-meter (zeroed with an SMD rig mounted) gives a reading of 10.48 pF. With a thumb on each terminal, it'll go over 180 pF.
