Hitachi's FM SHIELD™ is a magnetic shielding sheet made of high permeability FINEMET® FT-3M ribbon laminated with PET film. The sheets are thin, light weight and flexible, and easy to handle. FM SIELD™ have superior magnetic shielding effect especially in frequencies below several 100kHz. One layer can shield about 100µT and multiple layers allow shielding strong magnetic field. Having small deterioration in shielding effect by bending, cutting and punching, FM SHILED™ can be applied on curved surface and cut or punched in various shapes. Long sheet type is suitable for large-scale magnetic shield such as shielding room.

Applications:

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