1.3.2 Component Temperature Ratings - DLP3940SQ1EVM

The PCB materials and most of the PCB components are rated to operate between –40°C to 105°C, including the DLP3940S-Q1, the DLPC231S-Q1, and the TPS99002S-Q1.

Some components on board, such as switches, connectors, and indicator LEDs, do not meet this temperature rating. The specifications for EVM components which are not rated between –40°C to 105°C are listed in Table 1-2. Refer to the EVM bill of materials to review the temperature specifications of all components used in the EVM design.
