Leakage current measurements of high voltage ceramic capacitors

Leakage currents of NOVACAP Company NPO surface mount high voltage multilayer ceramic capacitors, type LS1808N102K302NX080, were measured before and after irradiation by 200 MeV protons at a fluence of 5 x 10(14)/cm(2). Two banks of 20 capacitors showed that the leakage current was < 1 x 10(-11) ampere. As we see from the results, the average current was very close to zero and the measurement accuracy was limited by the equipment sensitivity and the experimental setup noise.
