Marking for LCR:
The resistance code shall be marked on the resistor as follows (this code is the same for 1% and 5% tolerances):
0402 size:
no markings
0603 size:
3-digit markings using “R” and 2 digits. When “R” can not be used then 3 digits and underlined. (see below)
0805 – 2512 size: 4-digit markings using “R” and 3 digits. “Rxxx.” R010 = 10m ohm, R120 = 120m ohm.
Examples of 3-digit markings:
R01 = 10m ohm
022 = 22m ohm
068 = 68m ohm
R08 = 80m ohm
R10 = 100m ohm
