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 layer that is applied to the top surface of the substrate. The

composition of the resistive layer 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

environmental soldering issue, the outer layer of these end terminations is a Lead-free solder .

FUNCTIONAL DESCRIPTION

Product characterization

Standard values of nominal resistance are taken from the E192 & E24 series for resistors with a tolerance of

±1%, ±0.5%, ±0.25%, ±0.1%, ±0.05%. The values of the E24/E192 series are in accordance with “IEC

publication 60063”.

Derating

The power that the resistor can dissipate depends on the operating temperature; see Fig.2

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.

Storage and Handling Condition:

Products are recommended to be used up within two years. Check solderability in case

shelf life extension is needed.

To store products with following condition:

Temperature : 5 to 40℃

Humidity

3. Caution:

: 20 to 70% relative humidity

a. Don’t store products in a corrosive environment such as sulfide, chloride gas, or acid. It

may cause oxidation of electrode, which easily be resulted in poor soldering.

b. To store products on the shelf and avoid exposure to moisture.

c. Don’t expose products to excessive shock, vibration, direct sunlight and so on.

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 within lead-free solder bath. The

test condition for no leaching is 260°C for 30 seconds. Typical examples of soldering profile and condition that

provide reliable joints without any damage are given in Fig 3. and Table 1.
