1. Rating (watts at 70 C
degree)
- BB = 1/8 watt
- CB = 1/4 watt
- EB = 1/2 watt
- GB = 1 watt
- HB = 2 watt
2.
Resistance value: First two digits
are significant. The last digit indicates the number of zeros to follow,
except below 10 ohms:
- 101 = 10 with 1 zero = 100 Ohm
-
102 = 10 with 2 zeros = 1000 Ohm
-
27G = decimal point 2.7 Ohm
The letter "G" is substituted in
place of the third digit. The desired resistance value is then the first
two digits multiplied by 0.1.
3.
Resistance tolerance:
- 5 = ± 5 %
- 1 = ± 10 %
- 2 = ± 20 %
