## **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** 

- Good thermal conductivity with great EMI suppression within 1‐18GHz 

- Inherent surface tack typical of standard thermal gap fillers 

- Compliant with minimal component stress during assembly 

- Meets UL 94 V‐0 flame 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
