Electrically isolated metal tab.
Recommend the use of thermal grease between metal tab and heat sink.
Thermal design should account for a thermal resistance between resistor and tab of 5.9°C/W and a maximum resistor temperature of 155°C.
Current rating: 25A maximum.
Surface mount package also available, please call factory.
