Silicone Coated Waved Ribbon Power Wire Wound Resistors

DQR and DQN series (support Vitreous Enamel coating DQVR)


  • Also known as Corrugated Ribbon Power Resistor
  • Heavy Duty, Durable, Low Cost High Power Wire Wound Resistors for general purpose applications - Power Equipment Testing, High Power Circuits, Heating Resistors, Braking Resistors, Snubber Resistors in High Power Snubber Circuits.

  • DQR-F - Waved / Corrugated Ribbon Wirewound Resistors up to 20,000W ( 20kW )
  • DQN-F - Low Inductance Waved / Corrugated Ribbon Power Resistors up to 20,000W ( 20kW )
  • DQVR - Vitreous Vitreous Enamel Wire Wound Resistors : up to 1kW
  • Adjustable Power Resistors - DQS series is available.
  • Suitable for both continuous high power and short time overload dissipation applications

  • High surge current handling capacity
  • Improved heat radiation and convection designs
  • They can be as load resistors for load banks.
  • Support milli ohm (depending on the power ratings)
  • Support multi-resistances per resistor ( Multi-Terminals )
  • Support Vitreous Enamel coating for harsh conditions applications.
  • All resistance values are made according to the customers’ application needs.
  • As High Current Resistor applications, please state the working Current and loading time. Different Voltage can cause different resistor currents. In turn, different raw materials and production processes are needed to withstand the load resistor current and heat.

  • Precision Resistance Tolerance +/-0.1% +/-0.5% +/-1% +/-5% +/-10%

  • Support resistor power, resistance and resistor size not listed below.

  • We support High Power Wire Wound Resistors with various specifications for industrial applications. Different applications can have a very different resistor electrical and mechanical profile.
