DIELECTRIC FILM, FILM CAPACITOR, AND ELECTRIC DEVICE |
摘要 |
There are provided a dielectric film, a film capacitor and an electric device capable of achieving an increase in relative permittivity without causing a decrease in breakdown field strength. A dielectric film includes an organic resin and ceramic particles contained in the organic resin. The ceramic particles each have a crystal lattice defined by three axes composed of axis a, axis b, and axis c, and including two or more crystalline phases of different axial ratios c/a. Owing to each crystal phase having different extents of dielectric polarization originating from the differences in shapes (sizes) of the crystal lattices, the ceramic particles each have regions with different permittivities, achieving an increase in relative permittivity without causing a decrease in breakdown field strength. |
