Notes
(1)
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.
• 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.

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 board materials may be required to maintain the
reliability of the assembly.
Specified power rating above 125 °C requires dedicated heat-sink pads, which depend on board materials.
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 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.
For the high and low ohmic range, optimized Cermet
products provide comparable properties. The resistor
elements are covered by a 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)
.

ASSEMBLY
The resistors are suitable for processing on automatic
SMD assembly systems. They are suitable for automatic
soldering using wave, reflow or vapour phase as shown in
IEC 61760-1.
The encapsulation is resistant to all cleaning
solvents commonly used in the electronics industry,
including alcohols, esters and aqueous solutions. The
suitability of conformal coatings, if applied, shall be qualified
by appropriate means to ensure the long-term stability of the
whole system.
The resistors are RoHS compliant, the pure tin plating
provides
compatibility
with
lead
(Pb)-free
and
lead-containing soldering processes. Solderability is
specified for 2 years after production or requalification. The
permitted storage time is 20 years. The immunity of the
plating against tin whisker growth has been proven under
extensive testing.
All products comply with the
GADSL
(1)
and the
CEFIC-EECA-EICTA
(2)
list of legal restrictions on
hazardous substances. This includes full compliance with
the following directives:
