Abstract
A flexible capacitor is provided which is suitable for use in conjunction with a magnetic core for forming a CLC or pi filter, such as the type used for electrical connectors in the engine control hardware for an automobile. The flexible capacitor is generally composed of a flexible substrate having a surface on which interleaved conductor layers are supported. The interleaved conductor layers include at least two conductor layers, a first of which is composed of a plurality of islands of electrically conductive material which are electrically isolated from each other, while a second layer is composed of an electrically conductive material. A dielectric layer is disposed intermediate each adjacent pair of conductor layers so as to form a capacitive structure. The first conductor layer serves as the signal capacitor plate, while the second conductor layer serves as the ground capacitor plate. The islands of the first conductive layer are preferably arranged in at least two arrays which are spaced apart on the flexible substrate. The flexible capacitor overlays, and preferably wraps around, at least a portion of a magnetic core member, such that the core member forms an inductive element between capacitive elements of the pi filter.
