Hybrid Thermal/EMI Absorber


Overview

thermal conductive EMI absorber, Hybrid thermal EMI absorber
  • Hybrid Thermal/EMI Absorber (Thermal Conductive EMI Absorber) has the characteristics of a thermal interface sheet (silicone thermal pad) and a microwave noise suppression function at the same time.
  • It has excellent heat conduction (heat dissipation) effect due to excellent thermal conductivity and superior adhesive properties.
  • A wide frequency band (1MHz up to 3GHz) and a wide operating temperature range provide excellent product usability.

Features

  • Excellent thermal conductivity (Up to 3.0 W/mK)
  • Wide frequency band available (1MHz up to 3GHz)
  • A wide range of operating temperatures makes it versatile. (-40 to 150ºC)
  • It is very flexible and has excellent adhesion to the adherend.
  • Excellent flame retardancy
  • Can be processed into various shapes according to customer's requirements
