Mu-copper foil and sheets for EMI shielding can be used to shield plastic housings and enclosures or for complete shielding of existing rooms in buildings, to create a Faraday cage.
Many EMI problems can be solved easily by the use of conductive foils and conductive sheets. Some of the most commonly used materials are Mu-copper foil, reinforced Amucor foil and highly conductive textile.
All of theses materials can be produced with or without (conductive) self-adhesive and an optional insulation layer.
Mu-copper foil has superb shielding performance (also at low frequencies), can be soldered, and can easily be folded into the desired shape. Mu-copper foil is used to make small EMI shields like PCB-shielding cans, but also to EMI-shield entire existing rooms (Faraday cages, screen rooms, shielded boxes etc.).
Examples where Mu-copper foil is used
Similar to Mu-copper foil Part number 3281, but with a layer of paper added to insulate the top layer of the foil.

* For more information on the insulating layer, see table below. Note that by the thickness in the above table, the thickness of the insulation layer still needs to be added.
If you want that we provide an insulating layer on the Mu-copper then there are the following two options.
