RARA IRN100 Series

RARA IRN100 Series

The IRN100 flat and narrow type metal clad wire wound resistor series from RARA, offers a power rating of up to 100W on a heat sink and available resistance values between 1Ω and 1.1kΩ. These high power and low inductance resistors are designed for industrial and other applications where space is at a premium, the flat design also allows for excellent heat dissipation. The IRN100 series from RARA offers an extruded aluminium housing which provides strong and rugged protection, with options of cement or silicone filling materials as well as tolerances as low as ±0.5%. This resistor series offers a temperature range from -55°C up to +200°C (cement filling material).

  • Flat space saving metal clad wire wound resistor
  • Cement (standard) or silicone filling material with an extruded aluminium housing
  • 300mm flying leads 
  • Resistance ranges available between 1Ω and 1.1kΩ
  • TCR of +260 ppm/°C maximum
  • Tolerance values available of ±0.5%, ±1.0%, ±2.0%, ±5.0% and ±10.0%
  • Power rating of 100W (on a heat sink)
  • Insulation resistance of 20MΩ minimum
  • Temperature range between -55°C and +200°C (cement) or -55°C and +150°C (silicone)
  • Short time overload of 5 x power rating for 5 seconds

Typical applications for the IRN series include:

  • Motor drives
  • Braking and snubbing applications
  • Power sources for industrial equipment
