The IRM800 metal clad wire wound resistor series from RARA offers a power rating of up to 800W on a heat sink (360W in free air) with available resistance values between 0.1Ω and 112Ω (inductive design) or between 0.1Ω and 28.8Ω (non-inductive design). These high power resistors are available with tolerances of ±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 IRM800 series from RARA are a metal cover type with an extruded aluminium housing providing strong and rugged protection all with a temperature range from -55°C up to +200°C

  • Metal clad wire wound resistor
