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, composition
resistor. Look under the "type" heading to find composition. Then look under the "power and max voltage
ratings" headings to find 1W/500V. The style you select should be RCR32. This is the first part of the part
number. To find the last part of the desired part number, the ohmic value, refer to table 1-7, the resistor
type designation part number breakdown.
Tables 1-6 and 1-7 are excerpts from Military Standard 199C(MIL-STD-199C) and are included as
examples of the information contained in MIL-STD-199C. If another type of resistor is needed, the
complete part number breakdown can be located in MIL-STD-199C.
