The following 2512 SMT resistor…..
PF2512FKF7W0R007L (7 milliohm)
https://www.farnell.com/datasheets/1563633.pdf
What is the mounting description (ie area of surrounding thermal copper pour) that corresponds to the rating of this resistor as being 100% full power (ie 1W) up to 70degC ambient?
The attached doesn’t shed much light either on what could be the rating of the above resistor when mounted on a crowded , hot PCB in 70degC ambient, in a non-vented enclosure, with the resistor not necessarily being mounted to make use of convection current cooling…and no thermal via’ing to bottom layer copper pour/heatsink.
