AB-5000
EMI Absorber
Data Sheet
Product Description
3Μ™ AB-5000 Series EMI Absorber consists of
flexible soft metal flakes filler in polymer resin
with acrylic pressure-sensitive adhesive.
• Polymer resin and metal flakes filler
• Acrylic pressure-sensitive adhesive
• Supplied on a removable liner for easy
handling and die-cutting
The AB-5000 Series EMI Absorber is available in
standard A4 size and 210mm (width) X 15 meters
(length) in roll.
Applications
The AB-5000 Series EMI Absorber is typically
used for applications requiring electromagnetic-
absorbing performance. It suppresses radiated
noise from electrical devices for broadband radio
frequency ran g e .
Common uses include mobile phone (SAR
reduction), computer, digital still camera, RF
block, military equipments for radar avoidance
and stealth performance.
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.
The typical attenuation range of the 3M AB-5000
Series EMI Absorber depends on thickness.
