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 0.1Ω and 1.3kΩ (inductive design) or between 0.1Ω and 300Ω (non-inductive design). These high power resistors are available with tolerances of ±0.5%, ±1.0%, ±2.0%, ±5.0% and ±10.0% 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 -55°C up to +200°C
Typical applications for the IRH series include:
