Hello, the original nomenclature is 103 = 10 • (10 ^ 3) (10 ^ -12) = 10 • (10 ^ -9) = 10nF (subject: international system prefixes), and the p ~ could be interpreted as " alternating peak ", so it would be capacitor from 10nF to 250v. The K is the tolerance of said capacitor so it is not a multiple. You can also deduce the voltage by the location of said capacitor on the board. Greetings, I hope and serve you, any other questions just comment.
