FF Filter Foam Absorber
Product Image

ETS-Lindgren's Filter Foam/Vent Absorber series microwave absorber is similar in appearance and geometry to conventional ETS-Lindgren pyramidal and wedge type materials, and is tested to the same rigid specifications.

Key Features
  • Handles Approximately 10 Times More RF Power than Conventional Absorbers with Air Ventilation
  • Graded Dielectric Material

ETS-Lindgren's Filter Foam/Vent Absorber series microwave absorber is similar in appearance and geometry to conventional ETS-Lindgren pyramidal and wedge type materials, and is tested to the same rigid specifications. Normal incidence and wide-angle performance guarantees are the same for conventional EHP series absorbers.

The FF12-PCL absorber can safely withstand 2.8 kW/m2 of incident power without damage under room temperature (without forced air). It can handle more power with forced airflow through the absorber. For further information on power handling capabilities with forced airflow, please contact your ETS-Lindgren representative.
