High-temperature-resistant capacitor film

The utility model discloses a high temperature resistant capacitor film comprising a housing, the inner wall of the housing is fixedly connected with a metal foil, the inner wall of the metal foil is fixedly connected with a dielectric medium film, the inner wall of the dielectric medium film is fixedly connected with a composite thermal insulation layer, and the inner wall of the composite thermal insulation layer is fixedly connected with a sealing layer. The left side of the shell is fixedly connected with a sealing cover, and the left side of the sealing cover is fixedly connected with a lead. According to the utility model, through cooperative use of the shell, the metal foil, the dielectric medium film, the composite heat insulation layer, the sealing layer, the sealing cover, the lead, the flame-retardant layer and the high-temperature-resistant layer, the problems that a traditional high-temperature-resistant film capacitor has high-temperature-resistant performance but lacks effective flame-retardant
