 Marking method of MCR03
The description of markings on the chip resistor are as shown below.
① Marking method (J class):
The nominal resistance is expressed in by E-24series 3 digits.
The first 2 digits apply to the resistance value and the last one indicates
the number of zeros to follow. The R is used as a decimal point.
② Marking method (F/D class):
･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.
･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.
