Figure 2-The reduced power curve
	Rated Power Note- RNG4617 Series resistance connected to a suitable radiator for use. The maximum internal temperature is 130°C. Using the following formula: Where: RθH= thermal resistance of the radiator (K / W) RθR = electric resistance of thermal resistance (K / W) TMAx = maximum resistance maximum working temperature TA = Ambient temperature of radiator (℃) P = power of resistor (W)

 

Table 3-Line connection

For low resistance resistance (less than 10 Ω), the increase in the resistance and temperature coefficient of the copper pin exceeds the resistance itself. A four-legged Kelvin connection is recommended, as shown in the figure below. The load current on the V-pin will cause a measurement error.
