Marking Explanation
Resistors with 5 % tolerance may have a
3-digit or 4-digit resistance code.
Complete information about resistance
value and tolerance is found on the label
of the reel of chip resistors.
5 %: 3 digits, first two digits are
significant, third digit is number of
zeros to follow. Letter R is decimal point
for values from 1 to 9.9 ohms.
5 %: 4 digits, first three digits are
significant, fourth digit is number of
zeros to follow. Letter R is decimal point
for values from 1 to 99.9 ohms.
1 %: 4 digits, first three digits are
significant, fourth digit is number of
zeros to follow. Letter R is decimal for
values from 1 to 99.9 ohms.

Resistance Value
For 1 % Tolerance:
<100 ohms...............“R” represents decimal point (example: 24R3 = 24.3 ohms)
100 ohms ...............First three digits are significant, fourth digit represents number of zeros to follow (example: 8252 = 82.5k W)
For 5 % Tolerance:
<10 ohms .............. “R” represents decimal point (example: 4R7 = 4.7 ohms)
10 ohms ............... First two digits are significant, third digit represents number of zeros to follow (example: 474 = 470k ohms; 000 = Jumper)
