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.

  • \$\begingroup\$ Doesn't look like ceramic. Looks like film of some kind. I'd read .01 as 10nF. I'll see if I can find something. \$\endgroup\$

MKT means it is a metallized polyester film capacitor. 0.01 should mean 10nF, 63 means max AC voltage and K means 10% tolerance. The manufacturer logo is quite blurry, but regardless of that these should be identical between manufacturers.


.01 means .01 uF, MKT means metallized polyester, 63 means 63 volts, K means 10% tolerance I hope I got that all right.
