The IRH120 metal clad wire wound resistor series from RARA offers a power rating of up to 120W on a heat sink (96W in free air) with available resistance values between 0.1ฮฉ and 1.3kฮฉ (inductive design) or between 0.1ฮฉ and 300ฮฉ (non-inductive design). These high power resistors are available with tolerances of ยฑ0.5%, ยฑ1.0%, ยฑ2.0%, ยฑ5.0% and ยฑ10.0% as standard with other options available including flying leads or tab terminals, as well as inductive or non-inductive resistive windings. The IRH120 series from RARA has an extruded aluminium horizontal housing providing strong and rugged protection all with a temperature range from -55ยฐC up to +200ยฐC
Typical applications for the IRH series include:
