Abstract: An electrical component having a layered structure including first and second electrodes each having first and second electrode portions located in a plane and at least partially embedded in a dielectric body, each of the first and second electrode portions separated by a gap and substantially isolated by the dielectric, the first electrode substantially parallel to and at least partially overlapping the second electrode, wherein the first and second electrodes are electrically isolated and separated by the dielectric body.

Abstract: The invention relates to a capacitive structure comprising: first and second components, at least one component comprising a plurality of capacitive layers of a dielectric, each layer arranged between electrodes of different polarity, wherein the first and second components are arranged in a stack separated by a stress reducing layer having a supporting structure with an open mesh in which air acts to reduce the transmissibility of cracks through the stress reducing layer.

Abstract: A dielectric material suitable for use in an electronic component includes bismuth ferrite, strontium titanate and an additive. The additive comprises barium titanate. The barium titanate reduces the temperature capacitance change of the dielectric material and allows for increased working voltages. The material is useful for the construction of capacitors, and particularly capacitors intended for use at high temperatures. Also provided are a capacitor including the dielectric material, methods of manufacturing the dielectric material and the capacitor, and the use of an additive to improve the lifetime and/or reduce the dissipation factor of a capacitor.
