Abstract
Abstract Electrical RC elements comprised of dielectric foils and electrically conductive layers which are arranged alternately to form a stack wherein at least one of the conductive layers is formed of a high-resistance material, such as a chromium-nickel alloy and alternate conductive layers are staggered in relation to each other with at least one of the conductive layers being end-contacted. In preferred embodiments, such stacked layers are wound into a coil structure and include at least two insulating foils to prevent short-circuiting.
