(2) Recommend the use of thermal grease between metal tab and heat sink. (3) Thermal design should account for a thermal resistance between resistor and tab of 3.3 C/W and a maximum resistor temperature of 155C. (4) Resistances greater than 220 are available, please call factory. (5) Surface mount package also available, please call factory.
