The 3M™ EMI Absorber AB7000HF Series is a high-permeability magnetic EMI absorber for near-field applications. It consists of flexible polymer resin loaded with a filler of soft metal flakes for excellent absorption at frequencies from 300 MHz to 4 GHz. Target frequency range– the “sweet spot” for peak performance – is 800 MHz - 2.5 GHz. An acrylic non-conductive pressure-sensitive adhesive on one side makes applying the material easy and efficient. These sheet type EMI absorbers are excellent for absorbing near-field EMI inside and around electronic devices and assemblies.

Product performance
3M™ EMI Absorber AB7000HF series has an absorbing response to high frequency magnetic noise up to 4 GHz as a result of high magnetic loss (μ’’) peaking at ~ 300 MHz and low stored energy (μ’) at higher frequencies.
