Mu-copper foil 3281
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.
- Shielding plastic enclosure parts
- Shielding any non-conductive materials
- Ground plane
- Anti-static floor
- Electrical connection between surfaces (sheets / foils)
- Shielding in housings
- Shielding cables
- Temporary shielding during tests
- 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.).
- 3281 : Mu-copper foil (0.035 mm thick)
- 3282 : Mu-copper foil (0.12 mm thick)
- 3283 : Mu-copper foil (0.18 mm thick)
- High shielding performance
- Easy to solder (a tinned version is also available, Part number 3285)
- Flame retardant
Examples where Mu-copper foil is used
Tinned Mu-copper foil (3285)Similar to Mu-copper foil Part number 3281, but with a tin layer for corrosion protection and improved solderability.
Mu-copper foil with paper insulation (3287)
Similar to Mu-copper foil Part number 3281, but with a layer of paper added to insulate the top layer of the foil.
