Hybrid Thermal Transfer/EMI Absorber
CoolZorb 400 Series
HYBRID THERMAL/EMI ABSORBER
CoolZorb 400 is a hybrid absorber/thermal management material that is used for EMI
mitigation. Product is used like a traditional thermal interface material between heat source
such as an IC and heat sink or other heat transfer device or metal chassis. CoolZorb 400 also
functions to suppress unwanted energy coupling, resonances or surface currents causing board
level EMI issues.
FEATURES AND BENEFITS
•
Designed using silicone gel binder that imparts inherent tack typical of standard thermal
gap fillers
•
Filler particle composition imparts both good thermal conductivity and EMI suppression in
the microwave frequency range with best attenuation performance at or above 5 GHz.
•
Soft, compliant pad which exerts minimal stress on mating components during assembly
while providing good thermal transfer properties due to low interfacial resistance.
•
CoolZorb 400 passes UL94V0 requirements
VALUE
•
Performance advantage comes from dual functional properties of elevated thermal
conductivity and EMI reduction
•
Improved reliability performance of electronics
–
Better signal integrity due to reduction of EMI
–
Consistent performance of electronics due to temperature stability and low
outgassing properties of product
•
Improved EMC performance and resultant lower cost to meet compliance requirements
•
Environmentally friendly solution that meets regulatory requirements including RoHS
and REACH
