Datasheet

The IRH100 metal clad wire wound resistor series from RARA offers a power rating of up to 100W on a heat sink (80W in free air) with available resistance values between 0.1Ω and 1.1kΩ (inductive design) or between 0.1Ω and 240Ω (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 IRH100 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
