Customer ServiceThere 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.
Customer ServiceSelf-healing capacitors represent a significant advancement in capacitor technology, offering exceptional reliability, longevity, and performance across various applications. Their ability to automatically restore functionality after sustaining damage makes them invaluable in industries where performance and safety are critical.

Customer ServiceA theory of self-healing (SH) in metallized film capacitors (MFCs) is introduced.

Customer ServiceUnfortunately, 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.
Most of the work on self-healing capacitors to date has considered metallized polymers, 14,16, which consist of dielectric films with thin metallic electrodes at the surfaces.
Metallized-film capacitors have the property, even under high continuous voltage, to self-heal i.e., to clear a defect in the dielectric. The self-healing process is a consequence of a transient arc Proceedings of 2002 IEEE 14th International Metallized capacitors, under high DC voltage, suffer inhibited discharges named self-healing.
Metallized film capacitors have an ability to withstand the breakdown of dielectric film due to a “self-healing” feature. The optimal design of metallized electrodes' patterns guarantees high Owing to the property of self-healing, metalized film capacitors can be reliably used under high electric field.
Self-healing is the spontaneous extinction of a local electrical arc due to the destruction of the electrodes during the process. It occurs in capacitors made of metallized films of plastics with a thin layer of metal (the layer thickness e is ∼10 nm). This phenomenon was first studied by Heywang and Kammermaier , . They showed that
By employing an electroplating voltage of 2 V, a current density of 2 A/dm 2, and a plating time of 5 min, the ESR of the capacitor was minimized to 27 mΩ. Moreover, the Dissipation Factor (DF) of the capacitor was also enhanced.
