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.

Note

In applications with defined resistance ratios like voltage dividers or feedback circuits, an array with a defined tracking of e.g. 10 ppm/K is
required to replace discrete resistors with a temperature coefficient of ± 5 ppm/K. Furthermore, in order to achieve the same tolerance of
± 0.05 % of individual resistors, an array requires a matching of 0.1 %.

APPLICATION INFORMATION
R

DESCRIPTION
The production of the components 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 (96 % Al
and conditioned to achieve the desired temperature
coefficient. Specially designed inner contacts are realised 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 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*.

ASSEMBLY
The resistors are suitable for processing on automatic
SMD assembly systems. They are suitable for automatic
soldering using reflow or vapour phase as shown in
IEC 61760-1*. For ACAC resistor arrays automatic soldering
using can also be used. 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. The
permitted storage time is 20 years, whereas the solderability
is specified for 2 years after production or requalification. The
immunity of the plating against tin whisker growth has been
proven under extensive testing.
All products comply with the GADSL
CEFIC-EECA-EICTA
(2)
list of legal restrictions on
hazardous substances. This includes full compliance with
the following directives:
• 2000/53/EC End of Vehicle life Directive (ELV) an Annex II
(ELV II)
• 2002/95/EC Restriction of the use of Hazardous
Substances directive (RoHS)
• 2002/96/EC Waste Electrical and Electronic Equipment
Directive (WEEE)
(1)
and the
APPROVALS
Where applicable, the resistors are tested in accordance with
EN 140401-801 which refers to EN 60115-1 and EN 140400.
