Magnetic components and their production

摘要

A magnetic component (20) has conductor windings (22a, 22b) surrounded by insulation (21). In addition, the component (20) has a magnetic plate (23a, 23b) on each side. This is applied using conventional PCB process techniques. The magnetic plates enhance the inductance of the component in a manner which may be controlled by setting the configuration of the plates. For example a plate may have a number of isolated sections. Also, the plates on each side may be interconnected by plated through holes to provide a closed core.
