RW Series High Power SMD Wirewound Resistors 5 and 7 watt Ohmite has used its thermal management expertise to produce a unique resistor design. The resistor FeatuReS body incorporates fins identical to a heatsink. These Finned design facilitates cooling fins, as with a heatsink, increase the sur face area of High Power Density the part and allow for greater power dissipation. This unique design allows a small footprint for the SMD Wide Resistance Range device and a high power dissipation. These 5 and 7 Tight Tolerance watt resistors are extremely stable with a load life Low TCR drift of only 1%. A special flat has been designed in to the part for pick and place operations. chaRacteRiSticS RW5S0 RW7S0 Derating Power at 25C 7 watts 10 watts 100 at 70C 5 watts 7 watts 70 80 Resistance range 0.1 ~ 50K 0.1 ~ 100K 60 Non-inductive range 0.1 ~ 12.5K 0.1 ~ 20K 40 0.5%, 1%, 5% Tolerance 20 Temperature Coefficient 0.1 ~ 0.99: 90ppm 1 ~ 10: 50ppm 0 10+: 20ppm 0 25 50 75 100 125 150 Ambient Temperature, oC Operating temp. range -55C ~ +155C 1/2 Max. working voltage (PxR) 5.67g 11.34g Weight PeRFoRmance Data Temp. cycle (-55C to 125C, 1000 cycles) 0.5%+.05 (1000 hours at 25C) 1.0%+.05 Load Life Immersion (260C for 10 sec.) 0.1%+.05 Leaching (260C Solder immersion, 60 sec.)
