7. Marking
7.1
±0.1%
~ 1%
Resistance value is expressed by 4 digits, 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., 1001 =100
×10
1
= 1000Ω=1KΩ
7.2
±1%(RB06/E96)
When the marking space is too small in such small-sized resistors as RM06, the
marking can not made by 4 digits and may be made by two digits combined
with one English capital.
