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 .

For E24+E96, each resistor is marked with a four digits code on the protective coating to designate the
nominal resistance value. For values below 976 the R is used as a digit. For values of 100 or greater, the
first 3 digits are significant, the fourth digit indicates the number of multiple to follow.

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.

SOLDERING CONDITION
The robust construction of chip resistors allows them to be completely immersed in a solder bath of 260C 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 235C during 2 seconds within lead-free solder bath. The
test condition for no leaching is 260C 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.
