LFS Series High μ ShieldMINORU Emasfalis® LFS (Low Frequency Shielding Material) is a low-profile high permeability shield materials especially developed for effective low frequency magnetic shield within the confined space.
*Affected by application and usage such as noise attenuation, contact surface condition, material, and thickness. ‥
*In general, it is possible to increase the amount of noise attenuation by increasing the thickness of the noise suppression sheet.
LFS Low FRQ Magnetic Shield
LFS Series Absorber OverviewOverview | MINORU® Emasfalis® LFS (Low Frequency Shielding Material) is a multi layer composite material based on soft magnetic foil layer with protective PET cover film and acrylic pressure sensitive adhesive. | |
