The full power rating of Power Metal Strip resistors are dependent upon the ability of the circuit board to dissipate the heat energy created

in the resistance element. It is recommended to follow common design practices for power semiconductors that ensure the junction

temperature is maintained with in thermal limits by using large pad surfaces, thermal vias, heavier copper weights, internal layers as well as

other thermal spreading features. The thermal resistance values provided function in the same manner as junction to terminal temperature
