EMI Absorber AB6000, AB6000S,
and AB6000G Series
Product Description
3M™ EMI Absorber AB6000, AB6000S, and AB6000G Series consists of an insulation layer, shielding layer, absorbing
layer and non-conductive pressure-sensitive adhesive.
Features and Benefits
• Insulation Layer
• EMI Shielding Layer
• EMI Absorption Layer
• Pressure-sensitive Adhesive (PSA) Layer
• Supplied on a removable release liner for easy handling and die-cutting
Applications
The absorber is typically used for applications requiring both electromagnetic shielding performance and absorption
function. It is useful for electrical devises for broadband radio frequency range (mobile phone, PDA, PC, BS/CS tuner,
LAN, medical and military devices).
Common applications include attenuation of conduction and radiation noise suppression and filtering (FPCB and chips
on circuit, high speed microprocessor) and resonant peak of enclosed cavities (EMI/ESD), and electric/ electronic/ RF
components (IC/LSL, PCB, FPC, cable, oscillators, RF modules), mechanical bodies (metal can, frame, body, enclosure).
Attenuation and Power Loss
Many factors determine the true attenuation of electromagnetic shielding and absorbing material, including type and
thickness of polymer, adhesive type, 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 attenuation.
