BandSorb SC Series

BandSorb SC series is suitable for most consumer electronics, telecommunications infrastructure and medical device. The high magnetic loss of the BandSorb SC series is designed to exhibit high loss and are intended to be applied to metal surfaces. When placed on the inside of a microwave cavities BandSorb SC series will reduce the Q of the cavity, eliminate surface currents and generally dampen reflections.

BandSorb SC series materials can be supplied in sheets as well as custom die cut or kiss cut configurations. BandSorb SC materials can be supplied with or without pressure sensitive adhesive (PSA). Myriad options give you the customer flexibility when choosing which BandSorb SC product will work best in your design. BandSorb SC materials are available in standard thicknesses however we can offer custom sizes and thicknesses to suit your specific requirements.

Applications

BandSorb SC series provides a flexible solution that supports a wide range of EMI and RF suppression requirements.

Suppressing resonance and harmonics from circuitry, absorbing RF emissions from wiring, and reducing interference from internal peripheral devices are just a few examples of the use of BandSorb SC inside electronics housings (computers, server racks, switches,….)

BandSorb SC series can be used 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 through the absorption of microwave currents.

In the telecommunication market, the material can be applied to antenna elements, microwave dishes, the inner or outer surfaces of waveguides for isolation, attenuation, or modification of radiating patterns. 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-to-circuit 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 suppresses interference from on-board electronics, such as telematics, on-board radar-based systems, GPS circuitry, and display systems.
