Round-Wound Non-Inductive Resistors

(DRN)

Introduction (DR*N)

The Nonflammable Round-Wound Non-Inductive Resistor (DR*N) Series is lead-free and RoHS compliant.
Please contact us for details with your specific needs.

DR*N round-wire resistor applies Ayrton Perry non-inductive winding method to compensate residual inductance and to allow for efficient heat dissipation at higher temperature ranges.

Non-Inductance :
Ayrton Perry type non-inductive winding is applied. When required add "N" to the part number.

Resistance Tolerance :
K(±10%), J(±5%)
