7. Marking
7.1 ±0.1% , ±0.5% , ±1% (E96 ) : RB10 / RB12
Resistance value is expressed by 4 digits or 3digits , the first three digits represent the significant
figures of nominal resistance value inΩ, and the fourth digit represents exponent for base of 10.
E.G. : 1000 = 100×100 = 100Ω
7.2 ±0.1% , ±0.5% , ±1% (RB06/E96)
When the marking space is too small in such small-sized resistors as RB06, 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 .
