5.0   THERMAL 
5.1   Major Component Thermal Specifications 
Most of the major components used in Tegra 200 series Developer Board are listed in Table 39 along with the temperature 
range they are able to operate across. 
Note: 
The specifications noted in Table 16 may change and other versions with wider or 
narrower temperature  ranges may be available from the manufacturers 
Any design using these components must ensure each of these devices do not exceed the maximum temperature.  This may 
require careful board and mechanical design practices to accommodate various contributors to heat generation.

5.2   Thermal Considerations for Components 
Figure 27 and Figure 28 show the top and bottom of the Tegra 200 Series Developer Board.  The components that either 
generate heat, or may be very sensitive to temperature are highlighted with different colors: 
ƒ
 
Green:  Adversely sensitive to heat 
ƒ
 
Yellow:  Mild contributor to heat generation 
ƒ
 
Lt Orange:  Medium contributor to heat generation  
ƒ
 
Dark Orange:  Significant contributor to heat generation 
The Green coded devices may be significantly affected by temperature.  Typically these have more analog circuitry and may not 
perform as well hot such as the Camera Module.  The other highlighted parts contribute additional heat to the system which can 
be problematic to deal with in an enclosed mobile device.
