EMI Absorber
AB-5000S
Data Sheet
Product Description
3Μ™ EMI Absorber AB-5000S Series consists of
flexible, soft metal flakes filler in polymer resin
with acrylic pressure sensitive adhesive. It is
supplied on a removable liner for easy handling
and die-cutting
3Μ EMI Absorber AB-5000S is available in
sheets.
Applications
3Μ EMI Absorber AB-5000S is typically used for
applications requiring electromagnetic absorbing
performance. It is designed to suppress 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 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.
3Μ EMI Absorber AB-5000S typical attenuation
range is dependent on thickness.
