CoolZorb Hybrid Thermal EMI Absorbers

Laird CoolZorb is a traditional thermal interface material between a heat source, such as an IC, and a heat sink, another heat transfer device, or a metal chassis. Laird CoolZorb suppresses unwanted energy coupling, resonances, or surface currents, causing board-level EMI issues. The hybrid absorber/thermal management material of the CoolZorb series is designed using a silicone gel binder that imparts inherent tack, typical of standard thermal gap fillers. The filler particle composition imparts thermal conductivity and EMI suppression in the microwave frequency range with high attenuation performance at or above 3GHz. CoolZorb passes UL 94V-0 requirements and is RoHS and REACH compliant.
