The description of markings on the chip resistor are as shown below.
①
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.
Example:100k= 104
②
・
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 (01d100×10
Example : 3.01k= 47b
・
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
When the ambient temperature exceeds 70°C, power dissipation must be adjusted according to the derating curves below.
