Precision Thin Film Chip Resistor
Superior Moisture Resistivity
APPLICATION INFORMATION
The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow support
of the printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not
exceeded. Furthermore, a high level of ambient temperature or of power dissipation may raise the temperature of the solder joint,
hence special solder alloys or board materials may be required to maintain the reliability of the assembly.
These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift
increasing over operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a
functional lifetime. The designer may estimate the performance of the particular resistor application or set certain load and
temperature limits in order to maintain a desired stability.

Note
• The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a high level of ambient temperature or of
power dissipation may raise the temperature of the solder joint, hence special solder alloys or boardmaterials may be required to maintain the
reliability of the assembly. Specified power rating above 125 °C requires dedicated heat-sink pads, which depend on boardmaterials.
The given solder pad dimensions reflect the considerations for board design and assembly as outlined e.g. in standards IEC 61188-5-x, or in
publication IPC-7351. They do not guarantee any supposed thermal properties, particularly as these are also strongly influenced by many other
parameters.
Still, the given solder pad dimensions will be found adequate for most general applications, e.g. those referring to “standard operation mode”.
Please note however that applications for “power operation mode” require special considerations for the design of solder pads and adjacent
conductor areas.

DESCRIPTION
Production is strictly controlled and follows an extensive
set of instructions established for reproducibility. A
homogeneous film of special metal alloy is deposited on a
high grade (Al
2
O
3
) ceramic substrate and conditioned to
achieve the desired temperature coefficient. Specially
designed inner contacts are deposited on both sides. A
special laser is used to achieve the target value by smoothly
cutting a meander groove in the resistive layer without
damaging the ceramics. The resistor elements are covered
by a unique protective coating designed for electrical,
mechanical and climatic protection. The terminations receive
a final pure tin on nickel plating.
The result of the determined production is verified by an
extensive testing procedure and optical inspection
performed on 100 % of the individual chip resistors. Only
accepted products are laid directly into the paper tape in
accordance with
IEC 60286-3
(3)
.
