FM SHIELD™ Magnetic Shield Sheets
DESCRIPTION
This is a thin, lightweight, flexible, and easy-to-handle magnetic shielding sheet made by laminating a thin ribbon of the nanocrystalline soft magnetic material FINEMET® FT-3KM with PET film.
Features:
It exhibits excellent magnetic shielding performance especially in frequency bands below several hundred kHz.
Since the saturation magnetic flux density is as high as 1.23T, magnetic shielding of about 100μT is possible with a single phase.
By stacking layers, it is possible to shield stronger magnetic fields.
There is little deterioration in magnetic shielding performance due to processing such as bending, punching, and cutting, and it is easy to process into curved surfaces and various shapes. Long rolls are suitable for large-scale construction such as shielded rooms.
You can choose the most suitable product from two types: the standard specification product and the highly heat-resistant FINEMET®, which has a heat-resistant temperature of 130℃.

Table2. Comparison data
- High heat-resistant products can be used in environments with temperatures up to 130℃.
- The high heat-resistant product is thin at 0.05mm (40% compared to conventional products), so it can be used even in narrow spaces.
Application
- Measures against magnetic noise inside xEV
- Suppression of magnetic field noise inside electronic devices such as cameras, smartphones, computers, and tablets
- Magnetic noise countermeasures for medical X-ray diagnostic equipment
- Magnetic shielding around equipment that generates strong magnetic fields such as MRI
- Magnetic shielding for equipment susceptible to the effects of geomagnetism and fluctuating magnetic fields
