Filter for wire and cable

摘要

A filter for wires and cables comprising at least one pair of inner conductive wires made of an electrically conductive metal covered with an outer layer of magnetic absorbing material. This outer layer is formed from glass-coated microwires containing soft ferromagnetic amorphous material, preferably wound about the conductive wires to form a thin ferromagnetic layer. The filter may include two or more pairs of inner conductors with the ferromagnetic outer layers implemented separately or as a single common outer layer. The inner pairs of conductors may be either straight or twisted.
