Applications
■ 3Μ EMI Absorber AB-5000S is typically used for applications requiring electromagnetic absorbing performance. It is designed to suppress 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. 3Μ EMI Absorber AB-5000S typical attenuation range is dependent on thickness. 3M EMI Absorber AB 5000S Series – Typical Properties Properties Typical Value Type of Backing Polymer resin with metal flake filler Type of Adhesive Acrylic non-conductive pressure sensitive adhesive (PSA) Product Number AB5010S AB5020S AB5030S AB5050S AB5100S Thickness 1 0.10mm 0.20mm 0.30mm 0.50mm 1.00mm Standard packaging 210mm x 297mm Temperature range -25 ~ 85℃ Surface resistivity 2 1x10 6Ω(min)
