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.

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.
