RF absorbing material BandSorb®

EMI

Schlegel Electronic Materials (SEM) has developed the BandSorb® microwave absorbing materials with an electrical and magnetic property range that allows noise attenuation from 5 MHz to 40 GHz. Designers can easily integrate these materials into very tight spaces. SEM can provide this material with different configurations for use in the frequency range of 1 GHz up to millimeter waves. With our own dedicated on-site manufacturing and R&D team, we work closely with our customers to provide custom solutions when needed. RF Absorber Material Properties The BandSorb absorbers are available as silicone rubber elastomer and a dielectric foam absorber. The silicone rubber elastomers are available as: SC: Silicone rubber. Flexible, high-loss, magnetically loaded, electrically non-conductive silicone rubber. UC: Non-silicone, polyurethane rubber. Flexible, high-loss, magnetically loaded, electrically non-conductive silicone rubber. ST: resonant absorbers which reflect -20 dB or less. SN: ultra-thin, highly permeable EMI/RF absorber HP: ferrite sheets for NFC & Wireless Charging FB: Broadband flexible foam sheet absorber; lightweight high-loss carbon-impregnated dielectric foam Next to the silicone rubber material, a lightweight, high-loss carbon-impregnated dielectric foam absorber BandSorb FB. BandSorb FB provides a very low-cost solution over the thinner rubber absorbers. BandSorb can be used for applications requiring absorption across a wide range of frequencies such as antenna cross-talk and cavity resonance suppression.
