Description

The FRH 25C metal clad thick film resistor series from RARA offers a power rating of up to 15W on a heat sink and 5W in free air with available resistance values between 1kΩ and 2MΩ (non-inductive design). These high power resistors are available with tolerances of ±1%, ±2%, ±5% and ±10.0%. The FRH 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 -15°C up to +105°C.

  • Metal clad thick film resistor
  • Resistance range available between 1kΩ and 2MΩ
  • TCR of ±200 ppm/°C
  • Tolerance values available ±1%, ±2%, ±5% and ±10%
  • Power rating of 15W on a heat sink or 5W in free air
  • Insulation resistance of 20MΩ minimum
  • Temperature range between -15°C and +105°C
