3M EMI Absorbers

3M™ Electro-Magnetic Induction (EMI) Absorbers are flexible composite materials with specialized magnetic particles and a non-conductive PSA to absorb EMI. These absorbers feature high permeability and magnetic loss that help reduce EMI/RFI noise and improve signal integrity that could interfere with a system’s operations. The EMI absorbers are cost-effective and help increase the signal-to-noise ratio. These EMI absorbers help protect nearby electronic devices and components by absorbing EMI across multiple frequency bands. The 3M (TM) EMI/RFI absorbing solutions provide 3M(TM) EMI Absorbers and 3M(TM) Magnetic Isolators (ferrite sheets). For lower frequencies (<1 MHz), 3M™ Magnetic Shielding Materials can interact and influence EM fields to help protect sensitive electronic components and circuitry. Typical applications include computer systems, frames of mechanical bodies, and military equipment.
