The LS Series 0.050″ thick RF absorber material is an iron-loaded silicone elastomer optimized for the C and X bands (5.0 to 9.0 GHz). Designed for superior cavity resonance reduction, it covers a frequency range commonly encountered in Wi-Fi 5/6, sub-6 GHz 5G, and enterprise networking systems.

At 0.050″ thick, this sits between the 0.040″ and 0.060″ options, offering a balance of frequency coverage and profile thickness. Thicker options at 0.080″, 0.100″, and 0.125″ shift peak absorption to lower frequencies. For applications requiring a non-silicone alternative, consider the US Series acrylic elastomer.
