Mu-ferro shielding foil 6800 - SD

Magnetic shielding sheets that are thin and flexible with a high permeability

The Mu-ferro shielding 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 0.12mm the material is very flexible.

The mu-ferro shielding foil is lightweight and having a superior magnetic shielding effect. The best shielding frequency can be made when the frequency getws below several 100KHz.

When one layer of Mu-ferro foil is used it can shield 100μT. When multiple layers of the material are used it allow to shield a strong magnetic field.

Having small deterioration in shielding effect by bending, cutting and punching, Mu-ferro foil can be applied on curved surface and cut or punched in various shapes.

The foil is also available in a long sheet and is suitable for large-scale magnetic shielding for example a shielded room.

Applications

  • For suppression of magnetic noise generated from inductors in electronic devices, such as personal computer, mobile phone, DVC, DSC, etc.
  • For magnetic shielding of buildings or houses close to power lines or power distribution installation.
  • For magnetic shielding of equipments that easily affected by geomagnetic field or fluctuating magnetic field.
