DESCRIPTION

The resistors array is 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) solder alloy.

MARKING

No marking for WA04Y chip resistors array

FUNCTIONAL DESCRIPTION

Product characterization

Standard values of nominal resistance are taken from the E24 series for resistors with a tolerance of 5%,

1%. The values of the E24 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

CONSTRUCTION

R1=R2

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.
