Description

The RH 25C metal clad wire wound resistor series from RARA offers a power rating of up to 20W on a heat sink (8W in free air) with available resistance values between 0.27Ω and 25kΩ (inductive design) or between 0.1Ω and 10kΩ (non-inductive design). These high power resistors are available with tolerances of ±0.1%, ±0.25%, ±0.5% and ±1.0% depending the the resistance value required, as well as the option of inductive or non-inductive resistive windings. The RH 25C series from RARA has a cement moulding within an aluminium housing which mounts on to a chassis to utilise the heat sink effect, all with a temperature range from -55°C up to +250°C

  • Metal clad wire wound resistor
  • Inductive resistance range available between 0.27Ω and 25kΩ
  • Non-inductive resistance range available between 0.1Ω and 10kΩ
  • TCR from as low as ±40 ppm/°C between 20Ω and 25kΩ (inductive) or between 20Ω and 10kΩ (non-inductive)
  • Tolerance from as low as ±0.1% from 1Ω up to 25kΩ (inductive) or from 1Ω up to 20kΩ (non-inductive)
  • Power rating of 20W on a heat sink (8W in free air)
