Metal Oxide Resistors, Special Purpose, High Voltage
RNX
Vishay Dale
FEATURES
• Low TCR: ± 200 ppm/°C standard;
± 100 ppm/°C; ± 50 ppm/°C available
• Tolerance: ± 1 % standard to 1 GΩ; ± 5 %
above 1 GΩ; ± 0.5 % available in ± 50 ppm/°C
only. Special tolerance and/or temperature
coefficient matching available.
• High voltage (up to 8 kV)
• For oil bath or open air operation
• Matched sets available
• Special testing available upon request
• Compliant to RoHS Directive 2002/95/EC
Notes
•All resistance values are calibrated at 100 VDC. 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
(2) Continuous working voltage shall be or maximum working voltage, whichever is less.
(3) For resistance values above and below those listed please contact us
(4) Non-inductive ± 200 ppm/°C TCR only
