3M AB7000E Series
Harmonization Code : 8547.90.00.00 | Insulating fittings for electrical machines, appliances or equipment, being fittings wholly of insulating material apart from any minor components of metal (for example, threaded sockets) incorporated during moulding solely for purposes of assembly, other than insulators of heading 8546; electrical conduit tubing and joints therefor, of base metal
Main features
- 300 MHz-4 GHz operating range
- With or without adhesive
- -25 to 105°C temperature range
Product Description
3M™ EMI Absorber AB7000E Series is a flexible magnetic EMI absorber sheet for helping suppress near-field noise from 300 MHz to 4 GHz, with a target range of 800 MHz to 2.5 GHz. The absorber uses a polymeric resin filled with magnetic flakes and is offered with an optional non-conductive acrylic pressure-sensitive adhesive. Four magnetic-layer thicknesses from 0.10 to 0.50 mm are available in adhesive-backed and -WO configurations. The documented temperature range is -25°C to 105°C, with end-use environmental verification required.
Key features
- Frequency coverage: Operating frequency range of 300 MHz to 4 GHz with a target range of 800 MHz to 2.5 GHz.
- Magnetic absorber construction: Polymeric resin with magnetic flake filler for near-field EMI absorption.
- Adhesive options: Available with optional non-conductive acrylic PSA or in -WO versions without adhesive.
- Thickness options: Magnetic-layer thicknesses of 0.10, 0.20, 0.30 and 0.50 mm across the series.
- Shelf life: 18 months from manufacture in original packaging at 21°C (70°F) and 50% relative humidity.
Applications / Suitable for
- Mobile phones, computers, tablets and measurement devices
- Displays, camera modules, antenna-ground areas and sensors
- Cable wraps and electronic equipment for automobile applications

Additional Information
3M™ EMI Absorber AB7000E Series
3M™ EMI Absorber AB7000E Series is a flexible magnetic sheet for helping suppress near-field EMI noise from 300 MHz to 4 GHz. A polymeric resin loaded with magnetic flakes forms the absorbing layer, with optional non-conductive acrylic PSA for direct placement. Four magnetic-layer thicknesses and adhesive-free -WO variants support evaluation across compact electronic assemblies.

Construction and format
Design and placement evaluation
AB7000E performance is application-dependent. Evaluation should account for the target frequency, absorber thickness, XY coverage, orientation and location in the end-use assembly.
.
Shelf life is 18 months from the date of manufacture when the material is stored in its original packaging at 21°C (70°F) and 50% relative humidity.
Typical performance properties
Published technical values are representative or typical unless otherwise stated and should not be treated as guaranteed product specifications.
| Property | Value | Unit | Method / condition |
|---|---|---|---|
| Operating frequency range | 300 MHz to 4 GHz | — | Product operating range. |
| Target frequency range | 800 MHz to 2.5 GHz | — | 3M identifies this as the target or optimal range for peak performance. |
| Electrical resistivity | 1 × 106 | Ω·m | ASTM D257 type test method. |
| Typical permeability at 3 MHz | 100 | μ′ | Representative or typical value; permeability can vary with test method and equipment. |
| Temperature range | -25 to 105 | °C | Based on general environmental characteristics of the polymer binder resin; verify temperature and environmental performance in the end-use configuration. |
Series configurations
AB7000E variants use the same magnetic absorber family with different magnetic-layer thicknesses and adhesive configurations. -WO identifies versions supplied without the acrylic PSA layer.
| Variant | Magnetic layer thickness | PSA thickness | Total thickness | Adhesive configuration |
|---|---|---|---|---|
| AB7010E | 0.10 ± 0.02 mm | 0.03 ± 0.003 mm | 0.13 ± 0.02 mm | Non-conductive acrylic PSA |
| AB7020E | 0.20 ± 0.03 mm | 0.05 ± 0.005 mm | 0.25 ± 0.03 mm | Non-conductive acrylic PSA |
| AB7030E | 0.30 ± 0.03 mm | 0.05 ± 0.005 mm | 0.35 ± 0.03 mm | Non-conductive acrylic PSA |
| AB7050E | 0.50 ± 0.05 mm | 0.05 ± 0.005 mm | 0.55 ± 0.05 mm | Non-conductive acrylic PSA |
| AB7010E-WO | 0.10 ± 0.02 mm | N/A | 0.10 ± 0.02 mm | Without adhesive |
| AB7020E-WO | 0.20 ± 0.03 mm | N/A | 0.20 ± 0.03 mm | Without adhesive |
| AB7030E-WO | 0.30 ± 0.03 mm | N/A | 0.30 ± 0.03 mm | Without adhesive |
| AB7050E-WO | 0.50 ± 0.05 mm | N/A | 0.50 ± 0.05 mm | Without adhesive |
Thickness data are representative or typical. Total thickness is shown separately from magnetic-layer and PSA thickness so adhesive-backed and -WO constructions are not treated as equivalent.
Applications
3M identifies the following as potential application areas for AB7000E. Final effectiveness depends on the target frequency, thickness, part size, orientation and location in the end-use assembly.
