DESCRIPTION
The LEAD FREE resistors are constructed in a high grade ceramic body (aluminum oxide). Internal metal
electrodes are added at each end and connected by a LEAD FREE 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 nominated value within tolerance which controlled by laser trimming of this resistive
layer.
The resistive layer is covered with a BLACK 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/E96 series for resistors with a tolerance of ±5%
& ±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.
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 (JIS C 5201-1 : 1998)
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.
