**For resistance values above and below those listed please contact us.
• All resistance values are calibrated at 100 VDC. Calibration at other voltages available
• Part Marking: print marked - DALE, Model, Value, Tolerance, TC, Date Code (Model and Date omitted on RNX-1/4)
• Special Modifications:
- Special preconditioning (power aging, temperature cycling etc.) to customer specifications
- Non-helixed resistors can be supplied for critical high frequency applications. (Non-inductive).
