1. RCR = type:fixed composition resistors, insulated, established reliability
2. Rating (watts at 70 C degree)
3. Maximum ambient temperature and resistance temperature characteristic (refer to MIL--R-39008 specifications as Applicable)
4. Resistance value: First two digits are significant. The last digit indicates the number of zeros to follow, except below 10 ohms:
The letter "R" is substituted in place of a significant digit to represent the decimal point
5. Tolerance:
7.Failure rate level (at 50% rated wattage expressed in 5/1000 hrs.):
