3281 series - Mu-copper foil

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.


Applications

  • Shielding plastic enclosure parts
  • Shielding any non-conductive materials
  • Ground plane
  • Anti-static floor
  • Electrical connection between surfaces (sheets / foils)
  • Die-cuts
  • Shielding in housings
  • Shielding cables
  • Temporary shielding during tests

Options

  • Flame-retardant version
  • With (conductive) self-adhesive backing
  • With insulation layer
  • Cut into the desired shape (possible via CAD drawing)

Mu-copper foil (3281, 3282, 3283)

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.).
