6.9. Thermal Dissipation 
 
EM120R-GL&EM160R-GL are designed to work over an extended temperature range. In order to achieve 
a better performance while working under extended temperatures or extreme conditions (such as with 
maximum power or data rate, etc.) for a long time, it is strongly recommended to add a thermal pad or 
other thermally conductive compounds between the module and the main PCB for thermal dissipation. 
 
The thermal dissipation area (i.e. the area for adding thermal pad) is shown as below. The dimensions are 
measured in mm.
