The AB-5000-S Series from 3M are thin absorber sheets of polymer resin with magnetic filler, acrylic pressure-sensitive adhesive and release liner. It has enhanced absorption at lower frequencies (below 1 GHz). Backing thickness is 1.00 mm. They are applied on a removable liner for easy handling and die-cutting. Typically used for EMI absorbing, these sheets suppress radiated noise from electrical devices in the broadband frequency range. Common applications include mobile phone (SAR reduction), computer, digital still camera, RF block, and military equipment for radar and stealth environments. Learn more at the 3M website.
