DQ Tubular Wirewound Power Resistors
Wave-type Tubular
Wirewound
Power Resistors
Wave-Shape Ribbon-Wound Design
Neutralize Inductance Parasitoid (DQ)
Preview
Ribbon-Wound Power Resistor Construction:
● A tubular ceramic has two terminals, and is wound with a resistance element consisting of a
wave-shaped alloy ribbon.
● Terminal bands are spot welded after installation on the core and then a
resistance-alloy ribbon wire is crimped
and edgewound onto the core.
● Non-flammable resin insulation is applied
after cooling and drying through a
temperature process and then the
component mounts are attached.
● The resistance value range is relatively low
due to alloy material limitations; see the
DR series if upper resistance values required.
Features:
● Fixed, tapped styles, or adjustable type are available.
● Special terminals are available for unusual applications.
● Special tolerances, temperature coefficients, and resistance value can be specified.
● Ayrton Perry type non-inductive winding formats are available. See DQS Series when requied.
● Standard resistance tolerance is H(±3%), J(±5%) and K(±10%). Closer tolerances are available upon request.
● The wire is spot welded to the terminal bands and then “fastened” onto the core with a silicone, cement, or
vitreous enamel coating.
● Standard lug terminals available with or without terminal hardware. Single and double quick connect
terminals can be specified.
● DQ Series Design allows for efficient heat dissipation at higher temperature ranges so the resistor is
half the physical size of an equivalent rated roundwire resistor.
Applications:
● The Power Ribwound DQ Series is suitable for educational modeling applications, load testing, industrial
machinery, electric power distribution, instruments, automation control installations, lift trucks, overhead
cranes, elevators, arc and spot welders, battery chargers, machine tools, conveyors, and UPS systems.
Power Wave-Shape Ribwound Resistor supports the use of numerous taps, has low impedance, and can be
fabricated in various shapes to support a wide range of applications.
The DQ Series is RoHS compliant and lead free. For custom specifications, or order individual replacement
units, entire grids with various mounting configurations, please contact us to discuss the details.

Power Resistors
Preview
DQ-*N Power-Rib resistor applies Ayrton Perry non-inductive winding method to compensate residual
inductance and to allow for efficient heat dissipation at higher temperature ranges, so the resistor is half the
physical size of an equivalent rated round wire wound DR resistors.
Non-Inductance :
Ayrton Perry type non-inductive winding is applied. When required add “N” to the part number.
Resistance Tolerance :
K(±10%), J(±5%), H(±3%)
The power DQ-*N Wave-Ribbon Series is lead-free and RoHS compliant. Please contact us for
details with your specific needs.
