7. Marking
7.1 Type: 0805,1206,2010,2512
7.1.1 E96: 1%
Resistance value is expressed by 4 digits, the first “R” means decimal point
and the other digits represent for the normal resistance in Ω.
e.g., R100 =100 mΩ
7.1.2 E24: 2%,5%
Resistance value is expressed by 3 digits, the first “R” means decimal point
and the other digits represent for the normal resistance inΩ.
e.g., R10 =100 mΩ
7.2 Type: 0603
7.2.1 E96: 1%
When the marking space is too small in such small-sized resistors as RL06, the
marking can not made by 4 digits and may be made by two digits combined
with one English capital.

Notes :
When the resistance value is not in the list of E96 , 3 digitals with underline in E-24 series
is used as mark .
e.g., 0603 : 120mΩ, 1% Marking is 012
