    Abstract: A capacitor comprises an electrically conductive cylinder, an electrically conductive or semi-conductive cylindrical shell or shell segment arranged concentrically around the electrically conductive cylinder, and a dielectric arranged between the electrically conductive cylinder and the electrically conductive or semi-conductive cylindrical shell or shell segment. The dielectric comprises a particulate composite including a matrix material having a non-zero (e.g. negative) thermal coefficient of relative permittivity and a particulate filler material blended with the matrix material, the particulate filler material having an opposite (e.g. positive thermal) coefficient of relative permittivity. The positive thermal coefficient of relative permittivity is thereby selected such that the capacitance value of the capacitor is constant within a stability margin over a predefined temperature interval.
