AUSTIN, TX – 3M’s new EMI absorber AB-5000 series was created for EMI attenuation applications requiring electromagnetic-absorbing properties in mobile phones (SAR reduction), computers, notebooks, digital cameras, LCD/PDP TVs and PCBs for communications. This absorber reportedly suppresses radiated noise from emitting devices designed in the broadband radio frequency range.
 
The series is said to be different from other absorbers in that it is made with a flexible polyurethane resin loaded with a soft metal-flake filler. It has an acrylic, pressure-sensitive adhesive and is protected by a removable liner. The typical attenuation range of the absorbers in this series depends on thickness; the EMI absorbers in this series come in thicknesses of 0.1, 0.2, 0.3, 0.5 and 1mm. They are supplied in roll form, 210mm by 15M (8.26 inches by 16.35 yards) for the 0.1, 0.2, 0.3 and 0.5mm thicknesses and 210mm by 10M (8.26 inches by 10.9 yards) for the 1 thickness, making continuous rotary die cutting possible. The AB-5000 absorber is rated UL94V0 flame retarded.
