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 paste that is applied to the top surface of the substrate. The
composition of the paste 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
ease of soldering the outer layer of these end terminations is a Tin (lead free) alloy.

MARKING
For 5%, 1% E24 series, each resistor is marked with a three–digit code on the protective coating to designate
the nominal resistance value.
For 1% E96 series, each resistor is marked with a four–digit code on the protective coating to designate the
nominal resistance value.
For 1% E24/E96 overlapped values, each resistor is marked with three-digit code.
WK06V E96 has no marking!
Example:
105 = 1MΩ 1% , 5%, E24/E96
49R9 = 49.9Ω 1%, E96
123 = 12KΩ 1%, 5%, E24
FUNCTIONAL DESCRIPTION
Product characterization
Standard values of nominal resistance are taken from the E24/E96 series for resistors with a tolerance of
±1%, ±5%. The values of the E24/E96 series are in accordance with “IEC publication 60063”.
Derating curve
The power that the resistor can dissipate depends on the operating temperature; see Fig.2
Figure 2
Maximum dissipation in percentage of rated power as a function of the
ambient temperature
MOUNTING
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.
