6 FAQs about [Selling Kitga self-healing capacitors]
What are self-healing capacitors made of?
Self-healing capacitors are made of polypropylene film, vacuum metallized without impregnation, and cast resin.
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.
Are metallized film capacitors self-healing?
