Specifications subject to change without notice
Notes:
1. Electrically isolated metal tab.
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 5.9°C/W and a maximum resistor temperature of
155°C.
4. Current rating: 25A maximum.
5. For the resistance range 220Ω to 51KΩ, the power rating is restricted to 10W.
