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 0.9°C/W and a maximum resistor temperature of
155°C.
4. Resistances greater than 220Ω are available, please call factory.
5. Current rating: 25A maximum.
