3M AB7000HF Series EMI Absorber Data Sheet February 2009 Agency Approvals & Self Certifications 3M AB7000HF Series EMI Absorber consists of a flexible polymer resin loaded with soft metal flakes. An acrylic pressure-sensitive adhesive allows for easy application. • Low Halogen version of AB7000 absorber. Meets guidelines set forth in IEC • Flexible, high permeability magnetic sheets • One-sided acrylic pressure sensitive adhesive • Easily die cut into complex shapes RoHS 2002/95/EC RoHS Compliant 2002/95/EC” means that the product or part “Product” does not contain any of the substances in excess of the maximum concentration values in EU Directive 2002/95/EC, as amended by Commission Decision 2002/618/EC, unless the substance is in an application that is exempt under RoHS. This information represents 3M’s knowledge and belief, which may be based in whole or in part on information provided by third party suppliers to 3M. AB7000HF absorber 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 Typical Properties 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 AB7000HF absorber 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 AB7000HF absorber placed on a microstrip line.

Attenuation and Power Loss

Typical Properties

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 AB7000HF absorber 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 AB7000HF absorber placed on a microstrip line. The attenuation and noise dampening attained generally increases as the thickness of the material increases.
