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.
The typical attenuation range of the 3M AB-5000
Series EMI Absorber depends on thickness.
Applications
The AB-5000 Series EMI Absorber is typically
used for applications requiring electromagnetic-
absorbing performance. It suppresses radiated
