High temperature capacitors and method of manufacturing the same

摘要

A capacitor including a dielectric layer made of polyetherimide film having at least one fluorinated surface is disclosed. The capacitor also includes a metallized layer disposed on the fluorinated surface of the polyetherimide film. The capacitor further includes an electrode disposed on a side of the polyetherimide film opposite the fluorinated surface. A method for making a capacitor is also disclosed. The method includes plasma treating a surface of a polyetherimide film. The method also includes metallizing the surface. The method further includes disposing an electrode on an opposite surface and finally packaging the capacitor.
