as this is my first post I'm not quite sure as to how I should format this question but here goes. I am trying to sort a set of ceramic capacitors and I have come upon a few that I can't identify. When I look up the text on their sides (all the same) nothing if relevance comes up. I think they are 1nF, but I'm not sure. Any help with how to read these would be much appreciated. The tet says "MKT .01 63/K," Images below.
