Technical Data June 2014 3MTM EMI Absorber AB7000 Series Product Description 3MTM EMI Absorber AB7000 Series consists of a flexible polymer resin loaded with soft metal flakes. An acrylic pressure-sensitive adhesive allows for easy application. Features and Benefits * Flexible, high permeability magnetic sheets * One-sided acrylic pressure-sensitive adhesive * Easily die cut into complex shapes Applications 3M absorber AB7000 series is typically used for applications requiring EMI control and signal integrity improvement in the 50MHz to 10 GHz range. It is a broadband EMI absorber designed to work in near-field applications inside and around electronic devices and assemblies. Common applications include reduction of noise and crosstalk inside mobile electronics, reduction of crosstalk and EMI on ribbon cables and flex cables, reduction of radiated IC noise (applying absorber directly to the noisy IC), damping of radiation and oscillations inside shields and cavities, and increasing signal integrity on high speed data lines through crosstalk reduction. Attenuation and Power Loss Many factors determine the true attenuation of an electromagnetic interference absorbing material, including shape and thickness, intimacy of substrate contact, smoothness of application surface, strength and frequency of the EMI signal, etc. Since 3M absorber AB7000 series is a near field absorber, attenuation characteristics tend to be very application specific. Power loss characteristics are measured using a 5cm x 5cm square of 3M absorber AB7000 series placed on a 50 microstrip line. The attenuation and noise dampening attained generally increases as the thickness of the material increases. 3MTM EMI Absorber AB7000 Series 3MTM EMI Absorber AB7000 Series Typical Physical Properties Note: T he following technical information and data should be considered representative or typical only and should not be used for specification purposes.
