3M AB3000 EMI Absorbers
3M AB3000 Series EMI Absorbers and Magnetic Shielding Materials are high-frequency magnetic EMI absorbers designed for near-field noise suppression in applications operating from 1 GHz to 10 GHz. These absorbers are constructed from a composite of carrier resin, magnetic fillers, and an optional acrylic pressure-sensitive adhesive and deliver optimal performance in the 3 GHz to 7 GHz target frequency range. The material effectively absorbs electromagnetic energy, reduces unwanted EMI emissions, and helps improve electromagnetic compatibility by minimizing interference while providing magnetic shielding performance in compact electronic devices. Typical applications include mobile phones, camera modules, and avionics equipment.
