Figure 1-18.—Resistor color code.Table 1-6 is a resistor selection chart. As an example, let's suppose you need a 1-watt, compositionresistor. Look under the "type" heading to find composition. Then look under the "power and max voltageratings" headings to find 1W/500V. The style you select should be RCR32. This is the first part of the partnumber. To find the last part of the desired part number, the ohmic value, refer to table 1-7, the resistortype designation part number breakdown.Tables 1-6 and 1-7 are excerpts from Military Standard 199C(MIL-STD-199C) and are included asexamples of the information contained in MIL-STD-199C. If another type of resistor is needed, thecomplete part number breakdown can be located in MIL-STD-199C.1-50
