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:
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:
Green: Adversely sensitive to heat
Yellow: Mild contributor to heat generation
Lt Orange: Medium contributor to heat generation
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.
