AB7000HF EMI Absorber

3M™'s low-halogen, flexible, high-permeability magnetic sheet is a broadband absorber for near-field applications in the 50 MHz to 10 GHz range

Image of 3M's AB7000HF Absorber3M's AB7000HF (halogen free) absorber is typically used for EMI control and signal integrity improvement in the 50 MHz to 10 GHz range. It is a broadband EMI absorber designed to work in near-field applications inside and around electronic devices and assemblies. Common applications include reduction of noise and crosstalk inside mobile electronics, reduction of crosstalk and EMI on ribbon cables and flex cables, reduction of radiated IC noise (applying absorber directly to the noisy IC), damping of radiation and oscillations inside shields and cavities, and increasing signal integrity on high-speed data lines through crosstalk reduction.

* Halogen-free is defined as having maximum 900 ppm bromine, maximum 900 ppm chlorine, and/or maximum 1500 ppm total bromine and chlorine, per IEC 61249-2-21.
