Self-healing metalized film capacitors: Quo Vadis?

Metal film capacitors are ubiquitous components in modern electronics, playing an important role in energy storage, filtering, and voltage regulation. However, their performance and reliability can be reduced by partial electrical breakdowns caused by defects in the dielectric material. An attempt to partially mitigate this problem is the use of self-healing capacitors. The self-healing phenomenon significantly increases the service life of the device.
