DESCRIPTION
The resistors are constructed in a high grade ceramic body (aluminum oxide). Internal 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 request resistance to nominal value within tolerance which controlled by printing
process in 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 (Pb free) alloy.

MARKING
1.
For 0805, each resistor is marked with 3 digits or 4 digits on the protective coating to
designate the nominal resistance value. E24 series: 3 digits; E96 series: 4 digits. In case
E96 overlaps with E24, 3 digits should be marked.
2.
3.
For 0603 E24, each resistor is marked with 3 digits. No marking for E96!

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.
