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 tin layer for corrosion protection and improved solderability.
Similar to Mu-copper foil Part number 3281, but with a layer of paper added to insulate the top layer of the foil.
