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 [Self-healing capacitor application]
What is self healing metallized capacitor?
Self- healing is the ability of a metallized capacitor to clear a fault area where a momentary short occurs due to dielectric breakdown under voltage. The conditions that lead to a fault vary. In the production of the dielectric film, contamination can occur or a process control problem can result in compromised dielectric strength.
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.
Why should you choose a film capacitor with controlled self-healing?
Catastrophic failures and associated explosions or fires are unacceptable. Just as importantly, service lifetime and predictability for optimizing up-time are critical to the product's success. Film capacitors with controlled self-healing are the ideal solution to these challenges and can be obtained in various sizes and technical specifications.
What is a self-healing supercapacitor?
Self-healing materials are used in artificial intelligence (AI), aerospace, electronic skin, energy storage, and bionics. Self-healing conducting materials extend device life and enhance the performance of the supercapacitor device. Intrinsic and extrinsic mechanisms are employed for self-healing supercapacitors.
Can a self-healing mechanism do multiple healing in a supercapacitor?
Intrinsic self-healing mechanism can do multiple healing because it uses a reversible bond formation technique and does not require any external healing agent. But, it reduces the operating temperature range of the supercapacitor because healing material will creep. Also the glass transition temperature (Tg) is low of healing materials.
What are the advantages of metallized capacitors?
Metallized capacitors offer the advantages of volume efficiency and self-healing. Self- healing is the ability of a metallized capacitor to clear a fault area where a momentary short occurs due to dielectric breakdown under voltage. The conditions that lead to a fault vary.
