... The PCB area below the module can be used as an effective sixth side shield against EMI. Thermal Characteristics The case-to-ambient thermal resistance of the GS-R51212 module is about 5 C/W. This produces temperature increase of the module surface for a 10W of internal power dissipation. Depending on the ambient temperature and/or on the power dissipation, an additional heatsink or forced ventilation may be required ...
