Leakage current

When a direct voltage is applied to electrolytic capacitors, a low, constant current will flow through

temperature. (Graphs are shown below).

The absolute value of the leakage current of an electrolytic capacitor is determined by defects of

the dieletric. The (exclusive) usage of high-purity tantalum powder as raw material results in a low

total amount of defects and thus in a low leakage current level.
