soft metal flakes filler loaded polymer resin and
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
3MTM AB 5000 EMI absorber is ***ailable in
standard A4 size and 210mm (width) X 15 meters
(length) in roll.
Applicati***
3MTM AB 5000 EMI absorber is typically used for
applicati*** requiring electromagnetic absorbing
performance. 3MTM A***00 EMI Absorber
Suppresses radiated noise from electrical devices
for broadband radio frequency range.
Common uses include mobile phone (SAR
reduction), computer, digital still camera, RF
block, military equipments for radar ***oidance
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,
***oothness 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 AB 5000 series EMI absorber typical
attenuation range is dependent on thickness.
