1. The high-temperature resistant capacitor is characterized by being made of a high-temperature resistant capacitor film, wherein the high-temperature resistant capacitor film comprises a poly-4-methyl-1-pentene film, and a nano-scale Al or Zn/Al coating is vacuum evaporated on at least one surface of the poly-4-methyl-1-pentene film;

  • adding any one or combination of a plasticizer, an antioxidant and a heat stabilizer into the poly-4-methyl-1-pentene film;

    the thickness of the poly-4-methyl-1-pentene film is 2.5 to 25 mu m;

    the sheet resistance of the nano-scale Al or Zn/Al coating is 0.5 omega/□

    -300 omega/□

    , and the distribution form of grains and sheet resistance is not limited.
