EMI Absorber AB5000SHF Series (Halogen Free)
Product Description
3M™ EMI Absorber AB5000SHF Series (Halogen Free)* consists of flexible soft metal flakes filler loaded polymer resin
and acrylic pressure sensitive adhesive.
3M absorber AB5000SHF series is available in sheet type.
Technical Data August 2014
Applications
3M absorber AB5000SHF series is typically used for appli-cations requiring electromagnetic absorbing performance.
These absorbers are useful for electrical devices for broad-band radio frequency range (mobile phone, PDA, PC, BS/CS
tuner, LAN, medical and military devices).
This absorber series 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 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.
3M absorber AB5000SHF series’ typical attenuation range is dependent on thickness.
