Hi,
you would send 160mA through the voltage divider -> 0.15W of heat dissipation are produced at the resistors.
A SMD 603 is rated at about 0.1W. So the 5kOhm are out of specs. Using 10 and 1.24 gives you only 0.085A and 0.07W in the 10k resistor what is inside specs. So my pencil stroke makes the 1k resistor to be massive out of specs
