RESISTORS
FIG.1
DMR 16 RESISTOR
POWER RATINGS
Resistors shall have a power rating based on continuous full-load
operation at an ambient temperature of 70˚C. For temperature in
excess of 70˚C, the load shall be derated as shown in the figure 1.
VOLTAGE RATINGS
Resistors shall have a rated direct-current (DC) continuous
working voltage or an approximate sine-wave root-mean-square
(RMS) alternating-current (AC) continuous working voltage at
commercial-line frequency and waveform corresponding to the power
rating, as determined from the following formula:
RCWV = P X R
DMR SELECTION GUIDE
Where: RCWV = rated DC or RMS AC continuous working
voltage at commercial-line frequency and waveform (Volt)
P = Power rating (Watt)
R = Nominal resistance (Ohm)
In no case shall the rated DC or RMS AC continuous working
voltage be greater than the applicable maximum value.
NOMINAL RESISTANCE
Effective figures of nominal resistance shall be in accordance with
E-24 series, and resistance tolerance shall be shown by table 1.
