10 Description for Resistance Value Code and Marking of Thick Film Chip Resistor Resistance Value Code All the resistance value code of thick film chip resistor is corresponding with the marking. Marking E-24 ( 5%) 10 E-24 series: Express resistance value on the glass side with three digits, the first tow digits should be significant and the third one denote number of zeros. 10K 33 E-24 ( 1 %& 0.5%) E-24 series ( 1%& 0.5%) : One short bar under marking letter. E-96 E24 1%& 0.5% 4R02 4R03 E-96 series & E-24 series:for the dimension type of 4R02 4R03 express the resistance value with four digits, the first three digits are significant figures and the fourth de notes the number of zeros. K 133 E-96 E-96 For the dimension type of, express the resistance value with three code, the first two digit code denote the resistance of E-96 series, and the third code of letter denote the multiplier (see the table three and four ). 2M R The decimal point should be expressed by R The jumper should be expressed by 0 0 For the dimension type of there is no mark on the glass side. IEC IEC E24 For the resistance which don't belong to IEC serial, use the resistance of IEC serial which is most close to the required resistance of non-iec serial for replacement. To get agreement by both party if there special requirement for the marking. 88

11 PACKAGING AND PRECAUTION OF CHIP RESISTOR Description for Resistance Value Code and Marking of Thin Film Chip Resistor Resistance Value Code All resistance value code of thin film chip resistor,including size used four digits. Example TD03G4701BT 4701=4.7K 1R50=1.5 To use four digits code represent resistance value, Example 4701=4.7K 1R50=1.5 Marking E24 E96 E96. When resistance value belongs to E24 as well as E96 series, we suggest preferentially use E96 series. Example 10K=2, 103 Marking for Size Resistor For size resistor, express the resistance value with four digits code; Example K 4.7K Marking for Size Resistor -E96 For resistance value belongs to E96 series, express the resistance value with three digits code. Example E24 For resistance value belongs to E24 series, express the resistance value with three digits code. Example 4.7K 270K For the dimension type of there is no mark on the glass side.
