10 Description for Resistance Value and arking of Thick Film Chip Resistor Resistance Value All the resistance value code of thick film chip resistor is corresponding with the marking. arking E-24 (0603 5%) 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. K 33 E-24 (0603 %& 0.5%) E-24 series(0603 %& 0.5%): One short bar under marking letter. E-96 E24 %& 0.5% R02 4R03 E-96 series & E-24 series:for the dimension type of R02 4R03 express the resistance value with four digits, the first three digits are significant figures and the fourth de notes the number of zeros. 0K 33 E E-96 For the dimension type of 0603, 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 ). 2 R The decimal point should be expressed by R The jumper should be expressed by 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

When resistance value belongs to E24 as well as E96 series, we suggest preferentially use E96 series. K=02, arking for 2 20 Size Resistor 2 20 For 2 20 size resistor, express the resistance value with four digits code; 0K 0603 arking for 0603 Size Resistor 0603-E96 For resistance value belongs to E96 series, express the resistance value with three digits code E24 For resistance value belongs to E24 series, express the resistance value with three digits code. K The decimal point should be expressed by "R" For the dimension type of there is no mark on the glass side. 89

12 Use in various types of liquid, including water, oils, chemicals, and organic solvents. 2 Use outdoors where the products are exposed to direct sunlight, or in dusty places. 3 Use in places where the products are exposed to sea winds or corrosive gases, including Cl2, H2S, Nh3, SO2, and No2 etc. 4 Use in places where the products are exposed to static electricity or electromagnetic waves. 5 Use in proximity to heat-producing components, plastic cords, or other flammable items. 6 Use involving sealing or coating the products with resin or other coating materials. 7 Use involving unclean solder or use of water or water-soluble cleaning agents for cleaning after soldering : % 70% Avoid applying power exceeding normal rated power, exceeding the power rating under steady-state loading condition may negatively affect product performance and reliability. 2 Be careful when pick up the products with tweezers. There may be a care that the overcoat and / or the body can be chipped. 3 Soldering tip shall not touch the product when install product manually. 4 Storage conditions: T 5 30, RH 30% 70%.
