Low Dielectric Thermoset Materials

Hybrid Absorbers

Coolzorb 400

CoolZorb 400 a thermally conductive microwave absorber provides 2W/m*K thermal conductivity and good attenuation.  CoolZorb 400 assists design engineers simultaneously solve EMI compliance and thermal management issues that originate from a specific component or board.
Reduces the radiation of EMI noise from a heat sink that originates from a noisy chip Can be die-cut to a variety of shapes and componentsReduces the radiation of EMI noise from traces in a board while providing a thermal path for heat in the board to escape

Potential lower cost solution than a board-level shield without the tooling investment

Works in the microwave frequency range (targeted above 5 GHz)

Only recommended for use between two interfaces
