Thick Film Chip Resistors

01005/0201/0402/0603/0805/1206/1210/1812/2010/2512 Series 

1. Scope

1.1 This specification for approve relates to the Thick Film Chip Resistors manufactured by UNI-ROYAL. 

1.2 Small size & light weight. 

1.3 Reduction of assembly costs and matching with placement machine. 

1.4 Suitable for both wave & re-flow soldering. 

1.5 Applications: Navigator (GPS), Mobile Phone,Telecom, PDA, Setbox, Meter. 

2. Explanation of Part No. System

Part No. includes 14 codes shown as below: 

2.1 1st~4th codes: Part name. E.g.: 01005, 0201, 0402, 0603, 0805, 1206 ,1210, 2010,1812, 2512. 

2.2 5th~6th codes: Power rating. 

E.g.: W=Normal Size “1~G” = “1~16” 

Wattage 1/32 3/4 1/2 1/3 1/4 1/8 1/10 1/16 1/20 1 

Normal Size WH 07 W2 W3 W4 W8 WA WG WM 1W 

If power rating is lower or equal than 1 watt, 5th code would be “W” and 6th code would be a number or letter. 

E.g.: WA=1/10W W4=1/4W 

2.3 7th code: Tolerance. E.g.: D=±0.5% F=±1% G=±2% J=±5% 

2.4 8th~11th codes: Resistance Value. 

2.4.1 If value belongs to standard value of ≥5% series, 8th code would be zero,9th~10th codes are significant figures of the resistance and 11th code 

is the power of ten. 

2.4.2 If value belongs to standard value of ≤2% series, 8th~10th codes are significant figures of the resistance, and 11th code is the power of ten. 

2.4.3 11th codes listed as following: 

 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 N=10-5 P=10-6

2.5 12th~14th codes. 

2.5.1 12th code: Packaging Type. E.g.: C=Bulk T=Tape/Reel 

2.5.2 13th code: Standard Packing Quantity. 

 4=4000pcs 5=5000pcs C=10000pcs D=20000pcs E=15000pcs 

 Chip Product: BD=B/B-20000pcs TC=T/R-10000pcs 

2.5.3 14th code: Special features. 

E = Environmental Protection, Lead Free, or Standard type

4. Marking

(1) For 01005、0201 and 0402 size. Due to the very 

01005、0201、0402 small size of the resistor’s 

body, there is no marking on the body. 

(2)Normally, the making of 0 0603, 0 0805, 

0 1206, 0 1210, 0 1812, 0 2010, 

0 2512 resistors as following 0  0

(3) ±2%,5%Tolerance:The first two digits are 

significant figures of resistance and the third 

denotes number of zeros following 333  33K

(4) ±0.5%、1% Tolerance: 4 digits, first three 

digits are significant; forth digit is number of 

zeros. Letter r is decimal point. 2701  2.7K 

(5) More than 0805 specifications (including) 4 digits, 

Product below 1Ω, show as following, the first digit 

Is “R” which as decimal point. 

R300  0.3 

(6) Standard E-96 series values of 0603 ≤1% : due to the small size of the resistor’s body, 3 digits marking will be used to indicate the accurate 

resistance value by using the following multiplier & resistance code. 

Multiplier Code (for 0603 ≤±1% marking) 

9. Derating Curve

Resistors shall have a power rating based on continuous load operation at an ambient temperature from -55℃ to 70℃. For temperature in excess 

of 70℃, the load shall be derated as shown in figure 1 

Figure 1 

Voltage rating: 

Resistors shall have a rated direct-current (DC) continuous working 

Voltage or an approximate sine-wave root-mean-square (RMS) alternating-current (AC) continuous working voltage at commercial-line frequency 

and waveform corresponding to the power rating, as determined from the following formula: 

RCWV = P  R

Where: RCWV commercial-line frequency and waveform (Volt.) 

P = power rating (WATT.) R = nominal resistance (OHM) 

In no case shall the rated DC or RMS AC continuous working voltage be greater than the applicable maximum value. 

The overload voltage is 2.5 times RCWV or Max. Overload voltage whichever is less
