Magnetic shielding sheets that are thin and flexible with a high permeability
The Mu-ferro shielding foil is a magnetic shielding sheet made of a high permeable 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 shielding foil is lightweight and has superior magnetic shielding effect. The best shielding frequency can be made when the frequency gets below several 100 kHz.
When one layer of Mu-ferro foil is used it can shield 100 μT. When multiple layers of the material are used it can 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.
