See page 12 of [this][1] datasheet. In summary

> KEMET MIL-PRF-32535 ceramic capacitors will be marked in accordance
> with the military specification on case sizes ≥ 0805. Case sizes below
> 0805 will not be marked. Two sides of the ceramic body will be laser
> marked with a “K̄” to identify KEMET, followed by two characters to
> identify the capacitance value.
>
> The marking appears in legible contrast. Illustrated below is an
> example of an MLCC with laser the marking of “K̄A5”, which designates
> a KEMET device with the rated capacitance of 100 nF
