3M™ EMI Absorbers
Flexible EMI Absorbers for High-Performance Electronic Noise Suppression
Overview of 3M EMI Absorbers
3M™ EMI Absorbers are flexible composite materials that incorporate specialised magnetic particles and an optional nonconductive PSA to absorb near-field EMI.
They help protect nearby electronics from EMI by suppressing EMI noise at multiple frequencies. 3M absorbers are available with a wide range of performance characteristics for effective EMI management,mincluding a variety of thicknesses, resin systems, temperature ranges, a sheet and roll format, and with and without adhesive.
These thin, highly permeable magnetic absorbers help reduce EMI noise, help improve the signal-to-noise ratio for better system performance in some of the most extreme environments, and help enable thinner, lighter solutions.

Najczęściej zadawane pytania
Najczęściej zadawane pytania dotyczące 3M™ EMI Absorbers
Got questions about 3M™ EMI Absorbers? We've answered the most common queries about its performance, applications, and customisation options to help you choose the right solution for your project.
-
What custom shapes and formats can RGH provide?
As a precision converter, RGH can supply EMI absorbers in rolls, sheets, strips, or custom die-cut parts tailored to the exact geometry of your electronic housing or internal components. This ensures a perfect fit for complex layouts and fast integration into your manufacturing process.
-
What is the difference between an EMI absorber and an EMI shield?
While EMI shields (like copper or aluminum foils) reflect electromagnetic energy to block it from passing through, EMI absorbers contain specialised magnetic particles that actually soak up the noise and convert it into negligible thermal energy. Absorbers are ideal for eliminating internal reflections and suppressing near-field noise within a closed device.
-
How do I choose the correct thickness for an EMI absorber?
Absorbing performance is highly thickness-dependent. Thicker absorbers generally offer higher attenuation and work better at lower frequencies, whereas ultra-thin absorbers are optimised for high-frequency noise and tight spaces. Our technical team can help you select the exact thickness required to target your specific problem frequencies.
-
Can EMI absorbers be supplied with adhesive backing?
Yes. We can convert EMI absorbers with an optional pressure-sensitive adhesive (PSA)—available in both conductive and nonconductive options. This allows for quick, reliable peel-and-stick application directly onto components, shields, or enclosures during production line assembly.
-
How does an EMI absorber improve antenna performance?
When placed near internal antennas, absorbers suppress stray electromagnetic noise and crosstalk from nearby microprocessors or high-speed components. By cleaning up this background "noise," the absorber significantly improves the signal-to-noise ratio (SNR), leading to better wireless connectivity and device performance.
