Based on the market demand of high power DC capacitor and through comparison as well as analysis of electrolytic capacitor

super capacitor and metalized film capacitor

the author thinks that the metalized film capacitor possesses obvious advantages on performance

life and reliability in the range of medium and high voltage and will gradually replace traditional aluminum electrolytic capacitor.Its application examples and development trend are also described and it is expected to shorten the gap between the localized metalized film high power DC capacitor and that from the advanced countries as quickly as possible.
