Notes
•
All resistance values are calibrated at 100 V
DC
. Calibration at other voltages available.
• Part marking: Print marked - DALE, model, value, tolerance, TCR, 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)
(1)
Increase wattage by 25 % for 0.032" (0.813 mm) diameter leads
