A DEVICE FOR IMPROVING SHIELDING EFFECTIVENESS OF AN ELECTROMAGNETIC INTERFERENCE ENCLOSURE

摘要

A device for improving the shielding effectiveness of apertures used for mounting electrical component in an enclosure from Electromagnetic Interference (EMI). The device includes a hollow housing which contains a disc with an aperture, where the disc is attached to an inner surface of the housing to define a first and second inner space. The device also includes a ferrite core which is fit into the second inner space.
