EMI Design of Shielded Cable Assemblies

Most discussions on shielding for EMC address the shielding of enclosures and give rules of thumb regarding the size of slots and holes. These recommendations are not applicable in general to the design of shielded cable assemblies. Because there exists a gap in published information on the unique shielding requirements for cable assemblies, this document was generated. The scope of this document is that it will apply to low cost shielded multiconductor cable assemblies. While some of this information will be applicable to coaxial RF cable assemblies, this is not the main focus of this document.
