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.

Electrical insulation layer specifications

If you want us to provide an insulating layer on the Mu-copper then there are the following two options.

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.).

Part numbers
  • 3281 : Mu-copper foil (0.035 mm thick)
  • 3282 : Mu-copper foil (0.12 mm thick)
  • 3283 : Mu-copper foil (0.18 mm thick)

Tinned Mu-copper foil (3285)

Similar to Tape 3201, but with a layer of tin added for protection against corrosion and better solderability.

Mu-copper foil with paper insulation (3287)

Mu-copper foil is similar to Part number 3281, but with a paper layer added to isolate the top layer of the foil.
