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

nominated value within tolerance which controlled by laser trimming 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 pure Tin.

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.
