Riedon PFU Series

Riedon PFU Series

The PFU high power, high voltage and very low inductance resistor series from Riedon come in 800W or 1000W option. These resistors are available with a resistance range between 0.5Ω and 1MΩ, tolerance of 5% and TCR as low as 100ppm/K (between 1Ω and 1MΩ). These power film resistors offer very low inductance (108nH, terminal to terminal) and are vibration proof. They require mounting on a suitable heat sink (see data sheet for calculations) and liquid cooling is highly recommended.

  • High power and high voltage resistors
  • High power rating of 800W or 1000W
  • Resistance range between 0.5Ω to 1MΩ
  • Resistance value series E24+ (2Ω and 5Ω are also available)
  • Very low inductance (108nH terminal to terminal)
  • Vibration proof
  • Thermal resistance 0.10°C/W
  • Tolerance ±5% (J)
  • TCR of ±100ppm/°C between 1Ω and 1MΩ, and ±200ppm/°C 1Ω (for -55°C to +155°C)
  • Operating temperature −55°C to +175°C

Riedon PFU series high power, high voltage resistors cover the following applications:

  • Power Supplies
  • Motor Controls
  • Snubber Resistors
  • Load Banks
  • Robotics
