Claim Text:
1. A capacitor film comprising a metallized polymer support layer and one or more dielectric layers wherein the metallized polymer support layer is comprised of: a substrate layer; and a first electrode layer disposed directly on the substrate layer; wherein a first dielectric layer is disposed directly on the first electrode layer, the first dielectric layer comprising a thermoplastic polymeric material and at least one of inorganic ferroelectric or antiferroelectric particles, whereby the first electrode layer separates the substrate from the first dielectric layer and wherein the thermoplastic polymeric material is formed prior to application thereof directly onto the first electrode layer by blending a thermoplastic polymer and at least one of inorganic ferroelectric or antiferroelectric particles and, wherein the thermoplastic polymeric material has an elongation less than or equal to about 5 percent and wherein all of the inorganic ferroelectric or antiferroelectric particles present in the capacitor film are present in the one or more dielectric layers.
