US SERIES | RF ABSORBERS
Thin, flexible RF absorber solutions from 500 MHz to 3 GHz.
Our best selling low frequency RF absorber for thickness-critical applications
US Series Overview
Our US Series is an ultra-thin, high-permeability RF absorber engineered for low-frequency noise mitigation from 0.5 to 18.0 GHz, with an emphasis on 0.5 to 3.0 GHz. Unlike silicone-based absorbers, its acrylic composition offers superior magnetic permeability, making it highly effective at attenuating unwanted signals in large wavelength environments.
Available in 0.010″, 0.020″, 0.040″, and 0.060″ thicknesses, the US Series is ideal for space-constrained designs where mechanical fit is critical. Common uses include cable shielding for coaxial, ribbon, and multi-conductor cables in networking equipment, base stations, and industrial control panels.
It also performs as a cavity filler or enclosure liner, reducing RFI inside metal or plastic housings without adding bulk or impacting thermal management. Designers specify the US Series in wireless devices, automotive infotainment, and medical systems where RFI can degrade signal integrity or antenna performance.
With optional adhesive backing and in-house die-cutting, the US Series integrates easily into existing assemblies, delivering a cost-effective, flexible solution for engineers seeking reliable RFI suppression in commercial electronic systems.
