An example: RN R 50 H 1001 F M
RN | R | 50 | H | 1001 | F | M |

metal film resistor | terminal type | wattage rating | characteristic | resistance | tolerance | failure rate |
1 | 2 | 3 | 4 | 5 | 6 | 7 |
1. RN = metal film resistor
2. Terminal type (high reliability)
3.Wattage rating
4. Characteristic: (temperature coefficient) i.e., How much R will change per degree centigrade or "parts per million" 9PPM)
5. Resistance value: First three digits are significant. The last digit indicates the number of zeros: i.e.,
6. Tolerance:
7. Failure rate:
