Rib-Wound Power Non-Inductive
Resistors (DQ*N)- Within "DQ Series" Section :
- 1. Wave-type Wirewound Tubular Resistor (DQ)
- 2. Rib-Wound Non-Inductive Resistor (DQ-*N)
Introduction (DQ*N)
Rib-Wound Power Non-Inductive Resistor (DQ*N) applies Ayrton Perry 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 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 resistor is lead-free and RoHS compliant. Please contact us for details with your specific needs.
