Schlegel Electronic Materials (SEM) is pleased to introduce BandSorb® elastomer absorbers. Our new range of elastomer Cavity resonance (BandSorb® SC) Absorbers materials. The material 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 millimetre waves. With our own dedicated on site manufacturing and R & D team we are able to work closely with our customers to provide custom solutions where needed.
The BandSorb® absorbers are currently available as silicone rubber elastomer and a dielectric foam absorber.
The silicone rubber elastomer are available as:
SC: a flexible, high-loss, magnetically loaded, electrically non-conductive silicone rubber.
ST: a resonant absorbers which reflect -20 dB or less.
SH: a thermally conductive microwave absorber
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.
BandSorb® SN series is an ultrathin near field noise suppression absorber used for EMI control in electronic devices. The absorber is designed for the frequency range from 10 MHz up to 6 GHz. It is used to mitigate EM energy; it interacts and suppresses the magnetic field at the noise source.
BandSorb® SN series materials can be supplied in sheets as well as custom configurations, standard sheet size is 300 mm x 300 mm.
BandSorb® SN materials can be supplied with or without pressure sensitive adhesive (PSA).
Features and Benefits:
High magnetic permeability.
RoHs, Halogen Free, Reach compliant
BandSorb® SN series absorber can be placed over CPUs, main chip sets and other memory and power IC devices to suppress radiated noise causing interference with RF functions, crosstalk or SAR emissions. It can be used to suppress noise currents from circuit trace lines and flat cables that act like radiating antennas causing EMI problems and crosstalk issues.
