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.
