    The information may be there but not be obvious. Can you post a picture of the caps you received? Capacitor brand may help too. Do you have the ability to measure their capacitance?

    For capacitances 10pF and above, the first 2 digits are significant digits and the 3rd is the multiplier. 680pF would be 681, 68pF would be 680.

    Post a picture and indicate manufacturer.
