•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 4th digit denotes number of zeros.

•Standard E-24 series values which does not belong to E-96 series values (in ±1% tolerance) of 0603 size.
The marking is the same as 5% tolerance but marked with underline.
122 = 1200 = 1.2kΩ. 680 = 68Ω.
•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.
