The effect of several depolarizing agents on the electrical performance of CA35 highternperature(155℃) wet tantalum capacitors was studied. The results of 1000 hours-loading test show that CuSO4·5H2O and VOSO4
as a depolarizing agent of low-voltage and high-voltage capacitors respectively
can improve greatly the electrical performance of the capacitors
and the electrical parameters of the capacitors are superior to military standard SJ20207-92.
