EMI Absorber

January 8th, 2007

Although designed for use in end products, this absorber could also be used in test equipment…..Dan

The new 3M EMI absorber AB-5000 series is designed for EMI attenuation applications requiring electromagnetic-absorbing properties, such as in mobile phones (SAR reduction), computers, notebooks, digital cameras, LCD/PDP TVs and PCBs for communications. This absorber suppresses radiated noise from emitting devices designed in the broadband radio frequency range.

This series is 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 1.0 mm. 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 0.5 mm thicknesses and 210mm by 10M (8.26 inches by 10.9 yards) for the 1.0 thickness, making continuous rotary die-cutting possible. The AB-5000 absorber is rated UL94V0 flame retarded.
