Mu-Copper Tape

Mu-Copper Tape

 Mu-Copper Tape 3200

A large series of electrically conductive tapes for EMI/RFI shielding, ideal for grounding, conductance and EMI/RFI shielding of housings/Faraday cages.

Many EMI problems can be solved easily with Mu-copper foil or tape. Mu-copper tape is available with or without (conductive) self-adhesive and an optional insulation layer. Mu-copper tape can be cut to any width starting at 3mm and can be delivered from stock. The most commonly used width is 25mm; standard roll length is 16.5 meters.

When large surfaces are to be shielded, it is recommended to cover most of the surface with Mu-copper foil, possibly in combination with tape with a conductive self-adhesive. This solution is much cheaper than covering the entire surface with tape strips.

Mu-copper tape can also be delivered as die-cut, according to your drawing, on strips or in pieces (as stickers), with optional self-adhesive. Almost every shape and size is possible.

Shielding effectiveness

Many factors influence the actual effectiveness of an EMI/RFI shielding tape after it has been applied, such as the type and thickness of foil, type of adhesive, closeness of contact, smoothness of application surface, strength, and frequency of the EMI/RFI signal, etc. Still, attenuation values can be determined using standard tests and fixtures.

For EMI/RFI shielding tape, typical shielding effectiveness (far field) is in the range of 60dB to 80dB (10 kHz to 20 GHz).

  • EMI shielding of plastic enclosure parts
  • EMI shielding tape/gasket
  • Shielding of all non-conductive materials Ground plane
  • Anti-static floors (ESD floors)
  • Electrical connection between surfaces
  • Shielding in housings and Faraday cages
  • Temporary shielding during tests
  • Mounting transparent foils and windows for EMI/RFI shielding
  • Cable shielding (tape wrapped around cable)
  • Temporary shielding during emissions and immunity tests
