The symbols to indicate rated resistance are depicted in 3 characters (for the E6, E12 and E24 lines) or 4 characters (for the E48, E96 and E192 lines) as indicated below.
When a decimal point exists, the decimal point is represented by an R for all effective numerals.

In the case of 3 characters In the case of 4 characters In case of higher than 100ohm
The first and second character represent the effective numeral, and the third character is the multiplier following the effective numeral.

Example)
Rated Resistance Symbols Resistance
R15 0.15 ohm
1R5 1.5 ohm
150 15 ohm
151 150 ohm
152 1.5k ohm
153 15k ohm
154 150k ohm
155 1.5M ohm
156 15M ohm
157 150M ohm

The first, second and third character represent the effective numeral, and the fourth character is the multiplier following the effective numeral.

Example)
Rated Resistance Symbols Resistance
R154 0.154 ohm
1R54 1.54 ohm
15R4 15.4 ohm
1540 154 ohm
1541 1.54k ohm
1542 15.4k ohm
1543 154k ohm
1544 1.54M ohm
1545 15.4M ohm
1546 154M ohm
*The letters M and G are used as multipliers for 106 and 109 respectively of theresistance value expressed in ohms.

Example)
Rated Resistance Symbols Resistance
100M 100M ohm
1G00 1G ohm
10G0 10G ohm
100G 100G ohm
In case of less than 0.1ohm
