Application Notes

The ULM2000 metal clad wire wound resistor series from RARA offers a power rating of up to 650W in free air, with available resistance values between 2ฮฉ and 113ฮฉ (inductive design) or between 0.45ฮฉ and 30.5ฮฉ (non-inductive design). These high power resistors are available with tolerances of ยฑ1.0%, ยฑ5.0% and ยฑ10.0% as standard with tab terminals, as well as inductive or non-inductive resistive windings. The ULM2000 series from RARA are UL approved metal cover type with an extruded aluminium housing providing strong and rugged protection all with a temperature range from -55ยฐC up to +200ยฐC
