A Brief Introduction to the Self-healing of Metalized Film Capacitors

There are two different mechanisms for self-healing of metalized film capacitors: one is discharge self-healing; the other is electrochemical self-healing. The former occurs at higher voltage, so it is also referred to as high-voltage self-healing; because the latter also occurs at very low voltage, it is often referred to as low-voltage self-healing.

6 FAQs about [Do self-healing capacitors consume electricity ]

Can a self-healing process destroy a capacitor?

Unfortunately, this mechanism can be dificult to control, and in the worst case, a run-away process can result, causing the destruction of the entire capacitor in short order. To avoid this, KYOCERA AVX developed a controlled self-healing process in 1974 based on the segmentation of overall capacitance into elementary cells protected by fuse gates.

What is self-healing in polymer capacitors?

Self-healing in polymer capacitors involves (i) thermal rupture of the filaments, (ii) formation of voids in the cathode layers, and (iii) charge trapping in the polymer cathode that decreases anomalous currents caused by drying and discharging during breakdown. This work was sponsored by the NASA Electronic Parts and Packaging (NEPP) program.
