Softzorb™ GDS

Softzorb™ GDS

Low deflection force gap filler 18-35Ghz

SoftZorb GDS is a softer entry within Laird’s standard EccoSorb  product line. This softer material offers easier deflection for use in cavities whenever a lid may potential contact with and compress the absorber causing possible damage to other components. In addition, Softzorb GDS’ ability to more thoroughly fill the cavity greatly increases absorber performance by limiting leakage around the absorber.

This softer material can be used as an interface to fill the gap and/or balance stack up tolerances challenges without stressing the components neither the structure of the equipment.

Features and Benefits

  • High power performance and high magnetic loss.
  • Low deflection force enabling conformability for optimum cavity fill.
  • Antenna applications minimize reflections in transmission lines.
  • Useful in challenging compact and high tolerances stack up applications.
