DESCRIPTION

The resistors are constructed in a high grade ceramic body (aluminum oxide). external metal electrodes are added at both

end and connected by a resistive layer that is applied to the metallised rods. 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 film is covered by epoxy molding compound designed for electrical, mechanical and climatic protection,and

color code rings designate the resistance value.

Finally, the two external end terminations are added nickel plating and tin. 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 series for resistors with a tolerance of ±1%,

±0.5%, ±0.25%, ±0.1%. The values of the 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.

Cylindrical placement can be on ceramic rods 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 cylindrical 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.
