Riedon PF2274 Series

Riedon PF2274 Series
The PF2274 non-inductive, power thick film resistor series from Riedon offers all E12 resistance values in the range between 0.1Ω and 1MΩ, plus 2Ω and 5Ω, with a power rating of 300W. They offer standard tolerance of 5% (1% available upon request) and TCR as low as 100ppm/°C. The PF2274 power film resistors come in standard TO-227 housing with isolated back plate and M4x5mm screws included, and are available in three different terminal configurations. They require mounting on a suitable heat sink (see datasheet for calculations).
  • Power rating of 300W with heat sink (5W without heat sink)
  • Resistance range 0.1Ω to 1MΩ, nominal E12 plus 2Ω and 5Ω
  • Inductance as low as 14nH
  • Standard tolerance ±5%, ±1% available upon request
  • Thermal resistance as low as 0.23°C/W
