BandSorb SN Series

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.

Availability:
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

Applications:
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.
