Thermal Resistance RθJS -8.4 9.9 RθJC_real -4.3 4.6 RθJC_el -4.1 4.4 °C/W * Characteristics at TS=25°C.
* Radiant Flux value as per CIE 127:2007 standard.
* RθJS is the thermal resistance from the junction to the TS measurement point.
* Thermal resistance values (RθJC_real) determined by considering the energy conversion efficiency(ηe=3%). Refer to JESD51.
* The thermal resistance value (RθJC) is used to perform logical analysis (e.g. computer-based thermal analysis simulation) and
represents a thermal resistance between the die to the T C measurement point (PCB used: Aluminum PCB t=1.5mm, Insulating
layer t=0.12mm).
* For more details on thermal resistance, see CAUTIONS, (6) Thermal Management.
* It is recommended to operate the LEDs at a current greater than 10% of the sorting current to stabilize the LED characteristics. 1 NICHIA STS-DA1-5547A RANKS
