TECHNICAL DATA SHEET BandSorb® SC Magnetically loaded, electrically non-conductive silicone rubber EMI/RF absorber Description: Schlegel’s new range of elastomer Cavity resonance (BandSorb® SC) Absorbers materials consists of a thin, flexible, high-loss, magnetically loaded, electrically non-conductive silicone rubber. Schlegel can provide this material with different configurations for use in the frequency range of 1 GHz up to millimeter waves. With our own dedicated manufacturing site and R & D team we can work closely with our customers to provide custom solutions where needed. Availability: We supply BandSorb® SC series materials in sheets as well as custom die cut or kiss cut configurations. We can provide the BandSorb® SC materials with or without pressure-sensitive adhesive (PSA). A myriad of options gives our customers flexibility when choosing which BandSorb® SC product will work best in their design. BandSorb® SC materials are available in standard thicknesses; however, we also offer custom sizes and thicknesses to suit your specific requirements. Features and Benefits : Dielectric and magnetic loaded. RoHs, Halogen Free, Reach compliant Applications BandSorb® SC series provides a flexible solution that supports a wide range of EMI and RF suppression requirements.

Designers can also use BandSorb® SC series to reduce RF coupling between microwave components inside electronic housings. Typical applications include power amplifiers, oscillators and down/up converters. When bonded to a metal surface, the BandSorb® SC series will significantly reduce the reflectivity of metal objects or structures by absorbing of microwave currents. In the telecommunications market the material can be applied to antenna elements, microwave dishes, the inner or outer surfaces of waveguides for isolation, attenuation, or radiating patterns modifications. When applied to the side or even rear surfaces of certain objects, this material will cause a significant reduction in “head-on” reflectivity or backscattering. BandSorb® SC series can also be used for circuit-tocircuit EMI interference and reduction of unwanted emissions from the imaging CCD’s and LCD displays. In the automotive market, the BandSorb® SC series can be used to suppress interference from onboard electronics, such as telematics and GPS circuitry.
