3208 series - Mu-ferro foil and tape

Mu-ferro foil and tape have been developed for low-frequency (LF) magnetic field shielding

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.


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 tags

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).

We can slice all our EMI/RFI-shielding tapes to any specific width

Properties

  • Easy to bend
  • Easy to fold
  • Can be cut with scissors
  • Good corrosion resistance in a normal environment
  • Bending, folding, cutting, etc. 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.
