Package Thermal Specications
The 403GCX is designed to operate within the case temperature range from -40C to 120C. Thermal
resistance values are shown in Table 6:
Notes:
1. Case temperature TmC is measured at top center of case surface with device soldered to circuit board.
2. TmA = TmC – P×θCA, where TmA is ambient temperature.
3. TmCMax = TmJMax – P
×θ
JC, where TmJMax is maximum junction temperature and P is power consumption.
4. The above assumes that the chip is mounted on a card with at least one signal and two power planes.

Absolute Maximum Ratings
The absolute maximum ratings in Table 7 below are stress ratings only. Operation at or beyond these
maximum ratings may cause permanent damage to the device.
