Non-Inductive Round Wire Wound Power Resistors - DR-×N Series

Round Wire Wound Power Resistors - Non-Inductance

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%)

The power DR-×N Series is lead-free and RoHS compliant. Please contact us for details with your specific needs.
