EMI Absorber AB5000 Series
Product Description
3M™ EMI Absorber AB5000 Series consists of flexible soft metal flakes filler loaded polymer resin and acrylic pressure
sensitive adhesive.
3M absorber AB5000 series is available in standard A4 size and 210mm (width) x 15 meters length) in roll.
Features and Benefits
• Polymer resin and metal flakes filler
• Acrylic pressure sensitive adhesive
• Supplied on a removable liner for easy handling and die-cutting
Applications
3M absorber AB5000 series is typically used for applications requiring electromagnetic absorbing performance.
3M absorber AB5000 series suppresses radiated noise from electrical devices for broadband radio frequency range.
Common uses include mobile phone, computer, digital still camera, military equipment and associated electronic
equipment.
Attenuation and Power Loss
Many factors determine the true attenuation of an electromagnetic absorbing material, including shape and thickness,
intimacy of substrate contact, smoothness of application surface, strength and frequency of the EMI signal, etc. However,
using standard tests and fixtures, it is possible to determine a value for the signal attenuation.
3M absorber AB5000 series’ typical attenuation range is dependent on thickness.
