A theory of self-healing (SH) in metallized film capacitors (MFCs) is introduced. The interruption of the filamentary breakdown (BD) current in the thin dielectric insulation occurs when the thermally driven increase of the series impedance in the electrode metallization destabilizes the BD plasma arc. The interruption process can be described as a switching process which is self …
A dielectric material is placed between two conducting plates (electrodes), each of area A and with a separation of d.. A conventional capacitor stores electric energy as static electricity by charge separation in an electric field between two electrode plates.

plating time of 5 min, the ESR of the capacitor was minimized to 27 mX. Moreover, the Dissipation Factor (DF) of the capacitor was also enhanced. The utilization of a conductive polymer as the cathode layer provided the capacitors with self-healing characteristics that significantly decreased the leakage current (LC) in the capacitor.
Also, according to that document, it appears that film capacitors have lower leakage, in general, than ceramic capacitors. DC/DC converters often use film capacitors because of their self healing properties and the low leakage (I thought). I would think a capacitor with high leakage would not be as desirable for a DC-link capacitor actually.

Capacitors have ''leakage resistors''; you can picture them as a very high ohmic resistor (mega ohm''s) parallel to the capacitor. When you disconnect a capacitor, it will be discharged via this parasitic resistor. A big capacitor may hold a charge for some time, but I don''t think you will ever get much further than 1 day in ideal circumstances.
