Mu-ferro foil & tape

Series

Specify the width of MuFerro (max. 50 mm) in mm.
Length of the tape in meters.

Mu-ferro foil/tape is a thin foil; its thickness is only 0.023 mm. It combines excellent soft magnetic properties with unusual mechanical hardness and flexibility. This means that tight bends can be realised with only very slight impairment of permeability. The fine strip thickness and comparatively low electrical conductivity permit effective shielding even of higher-frequency fields. The roll can be ordered ordered up to 100 meter in length and a width up to 50 meter.


Applications

The primary applications of Mu-ferro foil/tape are flexible shielded cables with small diameters and rapid, flexible solutions to problems at low field strengths. 

Other applications
  • Magnet heads
  • Magnetic field sensors
  • Chokes
  • Transformers
  • Electronic article-surveillance tag

Advantages
  • Very high permeability
  • Low losses

Characteristics

Mu-ferro foil works well for shielding low-frequency magnetic fields. Due to the low electrical resistance it shields both low-frequency electric fields (LF) and high-frequency fields (HF). Comparable with Mu-Metal specifications.

Properties
  • Easy to bend
  • Easy to fold
  • Can be cut with scissors
  • Good corrosion resistance in a normal environment
  • Bending, folding, cutting does not cause major loss of attenuation
Grounding

Due to the highly conductive surface this material can be grounded easily to shield low-frequency (LF) electric fields. For professional grounding please contact us.

Mu-ferro foil with 0.15 mm thick, white insulation layer 3408
Mu-ferro foil with 0.22 mm thick, black insulation layer 3468

For a larger width we can recommend the tape the Mu-ferro shielding foil. The foil is a magnetic shielding sheet and made of a high permability material laminated on a PET film. The sheets are easy to handle and because of the thinness of 0.12 mm the material is very flexible.
The Mu-ferro SD shielding foil can be made on roll or sheet. Standard without adhesive but optional on request

  • On roll of max. 470 mm and a max. roll length of 100 m.
