3M Designs New EMI Absorber.AUSTIN, Texas -- A new EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. absorber from 3M is recommended for EMI attenuation Loss of signal power in a transmission. Attenuation The reduction in level of a transmitted quantity as a function of a parameter, usually distance. It is applied mainly to acoustic or electromagnetic waves and is expressed as the ratio of power densities. applications requiring electromagnetic-absorbing properties, such as in mobile phones (SAR (Segmentation And Reassembly) The protocol that converts data to cells for transmission over an ATM network. It is the lower part of the ATM Adaption Layer (AAL), which is responsible for the entire operation. See AAL. SAR - segmentation and reassembly reduction), computers, notebooks, digital cameras, LCD/PDP TVs and PCBs for communications. This absorber suppresses radiated ra·di·ate v. ra·di·at·ed, ra·di·at·ing, ra·di·ates v.intr. 1. To send out rays or waves. 2. To issue or emerge in rays or waves: Heat radiated from the stove. noise from emitting devices designed in the broadband radio frequency range. The new 3M EMI absorber AB-5000 series is different from other absorbers in that it is made with a flexible polyurethane polyurethane Any of a class of very versatile polymers that are made into flexible and rigid foams, fibres, elastomers (elastic polymers), surface coatings, and adhesives. 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. For more information on the 3M EMI absorber AB-5000 series, contact the 3M Electrical Markets Division at 800-676-8381.
