CoolZorb 400 Hybrid Thermal Transfer/EMI Absorber

Laird CoolZorb 400 Hybrid Thermal / Electromagnetic Interference (EMI) Absorbers suppress unwanted energy coupling, resonances, or surface currents with a 4.5g/cc density. This hybrid absorber / thermal management material is used as 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 designs the material using a silicone gel binder that imparts inherent tack typical of standard thermal gap fillers. The filler particle composition provides both good thermal conductivity and EMI suppression in the microwave frequency range, with ideal attenuation performance at or above 5GHz. The soft, compliant pad exerts minimal stress on mating components during assembly while providing good thermal transfer properties due to low interfacial resistance.
