OPERATING LIMITS
The maximum current rating of the CXA1304 is dependent on the case temperature (Tc) when the LED has reached
thermal equilibrium under steady-state operation. The graphs shown below assume that the system design employs
good thermal management (thermal interface material and heat sink) and may vary when poor thermal management is
employed. Please refer to the Mechanical Dimensions section on page 32 for the location of the Tc measurement point.
