Marking method of MCR03
The description of markings on the chip resistor are as shown below.
①
Marking method :
･
For the resistance value contained in E96 series.
The nominal resistance is expressed in 3 digits. The first 2 digits is
symbol to the resistance value and the last one is symbol to multipliers.
Example : 100k
= 01d (01d

)
Example : 3.01k
= 47b
(47b
301

= 3010
= 3.01k
)
･
For the resistance value not contained in E96 series and contained
in E-24 series.
The marking is expressed by E-24 series in 3 digits and one short bar
under the last marking letter.
Example : 390
= 391
