DESCRIPTION  
The resistors are constructed in a high grade ceramic body (aluminum oxide). Internal metal electrodes are  
added at each end and connected by a resistive paste that is applied to the top surface of the substrate. The  
composition of the paste is adjusted to give the approximate resistance required and the value is trimmed to  
within tolerance by laser cutting of this resistive layer.  
The resistive layer is covered with a protective coat. Finally, the two external end terminations are added. For  
ease of soldering the outer layer of these end terminations is a Tin (lead free) alloy.

FUNCTIONAL DESCRIPTION  
Product characterization  
Standard values of nominal resistance are taken from the E24 series for resistors with a tolerance of ±5%,  
and E96 series for resistors with a tolerance of ±1%. The values of the E24/E96 series are in accordance with  
“IEC publication 60063”  
Derating  
The power that the resistor can dissipate depends on the operating temperature; see Fig.2  
Figure 2  
Maximum dissipation in percentage of rated power as a  
function of the ambient temperature  
MOUNTING  
Due to their rectangular shapes and small tolerances, Surface Mountable Resistors are suitable for handling by  
automatic placement systems.  
Chip placement can be on ceramic substrates and printed-circuit boards (PCBs).  
Electrical connection to the circuit is by individual soldering condition.  
The end terminations guarantee a reliable contact.

ASC_WR_V_V06  
Jul-2011

SOLDERING CONDITION  
The robust construction of chip resistors allows  
them to be completely immersed in a solder bath  
of 260°C for 10 seconds. Therefore, it is possible  
to mount Surface Mount Resistors on one side of  
a PCB and other discrete components on the  
reverse (mixed PCBs).  
Surface Mount Resistors are tested for  
solderability at 235°C during 2 seconds. The test  
condition for no leaching is 260°C for 30 seconds.  
Typical examples of soldering processes that  
provide reliable joints without any damage are  
given in Fig 3.

TEST AND REQUIREMENTS  
Essentially all tests are carried out according to the schedule of IEC publication 115-8, category  
LCT/UCT/56(rated temperature range : Lower Category Temperature, Upper Category Temperature; damp  
heat, long term, 56 days). The testing also meets the requirements specified by EIA, EIAJ and JIS.  
The tests are carried out in accordance with IEC publication 68, "Recommended basic climatic and mechanical  
robustness testing procedure for electronic components" and under standard atmospheric conditions according  
to IEC 60068-1, subclause 5.3. Unless otherwise specified, the following value supplied :  
Temperature: 15°C to 35°C.  
Relative humidity: 45% to 75%.  
Air pressure: 86kPa to 106 kPa (860 mbar to 1060 mbar).  
All soldering tests are performed with midly activated flux.
