Description

The ULH100 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 being UL approved and 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 ULH100 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

  • Metal clad wire wound resistor
  • Inductive resistance range available between 0.1Ω and 1.1kΩ (flying leads) or 0.1Ω and 225Ω (tab terminals)
  • Non-inductive resistance range available between 0.1Ω and 240Ω (flying leads) or 0.1Ω and 225Ω (tab terminals)
  • Option of flying leads (tab terminals are standard)
  • 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 (80W in free air)
  • Insulation resistance of 20MΩ minimum
  • Temperature range between -55°C and +200°C
  • UL approved
  • Short time overload of 10 x power rating for 5 seconds
