Resistors BS1852 |
|
This is a clear and unambiguous shorthand way to write or label a resistor value.
You often see this notation on circuit diagrams because it takes up so little space.
Resistance | Normal | BS1852 |
0.47 Ohm | 0.47 Ω | R47 |
4.7 Ohm | 4.7 Ω | 4R7 |
47 Ohm | 47 Ω | 47R |
470 Ohm | 470 Ω | 470R |
4 700 Ohm | 4.7 kΩ | 4K7 |
47 000 Ohm | 47 kΩ | 47K |
470 000 Ohm | 470 kΩ | 470K |
4 700 000 Ohm | 4.7 MΩ | 4M7 |
You might encounter a code like this. 4K7J. The final letter denotes the resistor tolerance.
