The 3M™ EMI Absorber AB5000HF Series is magnetic EMI absorber with good attenuation at target frequencies. It consists of flexible polymer resin loaded with a filler of soft metal flakes for excellent absorption at frequencies from 800 MHz to 2 GHz. An acrylic non-conductive pressure-sensitive adhesive on one side makes applying the material easy and efficient. This sheet type EMI absorbers are excellent for near-field and cavity resonance applications inside electronic devices and enclosures.

The target frequency range – the “sweet spot” for peak performance – for 3M™ EMI Absorber AB5000HF Series – is 800 MHz - 2 GHz with the low-end of the operating frequency range at 300 MHz. Potential product usages include covering, attaching, or wrapping to: antennas, cables, display CoF, enclosures, PCBs, FPCs, semiconductor chips and sensors.
