7.0 Performance Specification:

8.0 Explanation of Part No. System:

The standard Part No. includes 14 digits with the following explanation:
8.1 This is to indicate the Chip Array Resistor size.
Example: 2D02,4D02,2D03,4D03,4DP3,16P8,2C02, 4C02, 4C03,2F01,4F01
8.2 5th~6th digits:
8.2.1 This is to indicate the wattage or power rating. To dieting the size and the numbers,
The following codes are used; and please refer to the following chart for detail:
W=Normal Size; “1”~“G”to denotes“1”~“16”as Hexadecimal:
1/16W~1W:

8.2.2 For power rating less than 1 watt, the 5th digit will be the letters W to represent the size required

& the 6th digit will be a number or a letter code.
Example: WG=1/16W
8.3 The 7th digit is to denote the Resistance Tolerance. The following letter code is to be used for indicating

the standard Resistance Tolerance.

F=±1% G=±2% J=±5% K= ±10%

8.4 The 8th to 11th digits is to denote the Resistance Value.
8.4.1 For the standard resistance values of E-24 series, the 8th digit is “0”,the 9th & 10th digits are to denote the significant figures of the resistance and the 11th digit is the number of zeros following;
For the standard resistance values of E-96 series, the 8th digit to the 10th digits is to denote the significant figures of the resistance and the 11th digit is the zeros following.
8.4.2 The following number s and the letter ally to indicate the Packing Quantity of Tape/Box & Tape/Reel packaging types. The following letter code is to be used for some packing quantities:

1=1000pcs 2=2000pcs 3=3000pcs 4=4000pcs
5=5000pcs C=10000pcs D=20000pcs E=15000pcs
8.4.5 For some items, the 14th digit alone can use to denote special features of additional information

with the codes are to be used to indicate the number of zeros in the 11th digit:
0=100 1=101 2=102 3=103 4=104 5=105 6=106 J=10-1 K=10-2 L=10-3 M=10-4
8.4.3 The 12th, 13th & 14th digits.
The 12th digit is to denote the Packaging Type with the following codes:
C=Bulk in (Chip Product) T=Tape/Reel
8.4.4 The 13th digit is normfollowing codes:
E=For “Environmental Protection, Lead Free type”of Chip.

11.0 Precaution for storage/Transportation:
11.1 UNIOHM recommend the storage condition temperature: 15℃~35℃, humidity :25%~75%.
(Put condition for individual product)
Even under UNIOHM recommended storage condition, solderability of products over 1 year old. (Put condition for each product) may be degraded.
11.2 Store / transport cartons in the correct direction, which is indicated on a carton as a symbol.
Otherwise bent leads may occur due to excessive stress applied when dropping of a carton.
11.3 Product performance and soldered connections may deteriorate if the products are stored in the following places:
a. Storage in high Electrostatic
b. Storage in direct sunshine,rain and snow or condensation
c. Where the products are exposed to sea winds or corrosive gases, including Cl2, H2S3 NH3, SO2, NO2.
