Our LS Series is a low frequency RF absorber material engineered for RFI mitigation in the 1.0 to 4.0 GHz range. Made from iron-loaded silicone rubber, the LS Series provides superior performance across this broad spectrum, making it ideal for suppressing interference from Wi-Fi, cellular, and broadband communication systems.

With thicknesses tailored for both effectiveness and ease of integration, the LS Series is commonly used in telecommunications equipment, wireless access points, consumer electronics, and industrial systems operating across multiple frequency bands. Its flexible construction accommodates conformal placement in and around complex assemblies.

The LS Series also helps reduce coupling and crosstalk in high-density electronic enclosures, particularly in smart home devices, enterprise networking gear, and advanced metering systems. When paired with optional adhesive and die-cut to spec, it offers a low-cost, production-ready solution for frequency-tuned RFI control.
