This series is an ideal solution for
the output side of high speed pulse
generators, a surge absorption
resistor in switch mode power
supplies and for monitors, display
terminals, scientific workstations
and other brown and white goods.

* With a 5.8°C watt heatsink or better at a 25°C ambient temperature, 20 watts can be dissipated
A larger heatsink will allow the resistor to run at a lower temperature.
