Marking on the Resistors Body:
•
•
For 0402 size, no marking on the body due to the small size of the resistor.
±5% tolerance product. (Including resistance values less than 1Ω; both 1% and 5%) The marking is 3 digits,
the first 2 digits are the significant figures of the resistance and the 3
rd
digit denotes number of zeros.
Below 10Ω shown as this:
6R8
= 6.8Ω
0.1Ω~0.99Ω shown as this:
R33
= 0.33Ω
153
= 15000Ω = 15KΩ;
120
= 12Ω
•
±1% tolerance marking of case size 0805 and bigger is 4 digits, the first 3 digits are the significant figures
of the resistance and the 4
th
digit denotes number of zeros.

Standard E-96 series values (±1% tolerance) of 0603 size. Due to the small size of the resistor’s body, 3 digits
marking will be used to indicate the accurate resistance value by using the Multiplier code & Standard E-96 Series
