EMI/RFI Absorbers

3M EMI absorbers eliminate noise from a few hundred megahertz to multiple gigahertz frequencies

Image of 3M's EMI/RFI Absorbers3M EMI absorbers are near field absorbers that are specifically designed to eliminate noise from a few hundred megahertz to multiple gigahertz frequencies. They work by absorbing the EMI field generated by today's high-speed electronics, eliminating emissions, crosstalk, and oscillations. They are flexible polymer sheets that are loaded with specific magnetic flake particles and are nonconductive, so they can be directly applied to circuitry and noisy traces without fear of shorting out traces and IC pins. They come in sheet or roll form for easy converting into custom shapes, and once cut, can be placed in tape and reel format for automatic insertion. They are UL94V-0 flame retardant and come in varying thicknesses up to 1mm.

3M absorbers are currently being used in millions of products around the world, including laptops, cell phones, routers, mobile radios, cameras, PDA's, and many other electronic devices. When shielding is impractical or not quite effective enough, consider using 3M absorbers for similar applications.

AB5000 Series

AB5000 series EMI absorbers consists of flexible soft metal flakes filler in polymer resin with acrylic pressure-sensitive adhesive. This EMI absorber is typically used for applications requiring electromagnetic absorbing performance. It suppresses radiated noise from electrical devices for broadband radio frequency range. These absorbers are commonly used for mobile phones (SAR reduction), computers, digital still cameras, RF blocks, and military equipment for radar avoidance and stealth performance.

Features
  • Polymer resin and metal flakes filler
  • Acrylic pressure-sensitive adhesive
  • Easy handling and die-cutting
  • RoHS compliant

AB6000 Series

AB6000, AB6000S, and AB6000G series EMI absorbers consist of insulation layers, shielding layers, absorbing layers, and nonconductive pressure-sensitive adhesives. These absorbers are typically used for applications requiring both electromagnetic shielding performance and absorption function. It is useful for electrical devises for broadband radio frequency range, including mobile phones, PDAs, PCs BS/CS tuners, LAN, and medical and military devices.

Features
  • Insulation layer
  • Pressure-sensitive adhesive (PSA) layer
  • EMI absorption layer
  • EMI shielding layer
  • Easy handling and die-cutting
  • RoHS compliant

AB7000 Series

AB7000 series EMI absorbers consist of a flexible polymer resin loaded with soft metal flakes. An acrylic pressure-sensitive adhesive allows for easy application. The AB7000 is typically used for applications requiring EMI control and signal integrity improvement in the 50MHz to 10GHz 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.

Features
  • Flexible, high permeability magnetic sheets
  • One-sided acrylic pressure-sensitive adhesive
  • Easily die cut into complex shapes
  • RoHS compliant

Tech Tips

EMI/RFI Absorbers
EMI noise in equipment can cause operational problems and also make it difficult to obtain FCC certification of new products. EMI can be generated by numerous electronic devices due to the speed and complexity of modern electronics. Many EMI problems show up when the finalized new product is close to introduction, leaving little time for complex redesign. How can this noise be eliminated or reduced without using complex shielding schemes or redesigning a circuit layout? More...
