3-digits marking(5% : 2512, 2010, 1206, 0805, 0603 )
Each resistor is marked with a three digits code on the protective coating to designate the nominal resistance value.
3-digits marking(1% : 0603)
Nominal resistance
Description
1.E-24 series
As 0603 WR06X 5%.
2.E-96 series
The 1st two digit codes are referring to the CODE on the table, the 3rd code is the index of resistance value :
Y=10-2,X=10-1,A=100,B=101,C=102,D=103,E=104,F=105
EX :
17.8Ω=25X,178Ω=25A,1K78 =25B
17K8=25C, 178K=25D, 1M78=25E
3. Remark
There is no marking for the items are not under E-24 and E-96 series
