RESISTORS DMR 16 RESISTOR SECTION 1 FIG.1 TABLE 1 RATINGS 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 SECTION 4 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 Rated Power Max. Working Voltage Max. Overload Voltage Rated ambient temp. Operating Temp. Range Resistance tolerance Resistance range 0.4W at 70˚C 200V 400V 70˚C -55˚C to +155˚C ± 1% 10Ω to 1MΩ CONSTRUCTION No. Name 1 Basic Body 2 Resistor 3 End Cap 4 Lead Wire 5 Joint 6 Coating 7 Colour Code 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) Material Rod type ceramics Metal Film Steel (Tin plated Iron surface) Annealed Copper wire (electrosolder plated surface) By welding Insulated resin (colour - apple green) Epoxy resin In no case shall the rated DC or RMS AC continuous working voltage be greater than the applicable maximum value.
