ACAS 0606 AT and ACAS 0612 AT precision automotive
grade thin film chip resistor arrays with convex terminations
combine the proven reliability of discrete chip resistors with
the advantages of chip resistor arrays. Defined tolerance
matching and TCR tracking make this product perfectly
suited for applications with outstanding requirements
towards stable fixed resistor ratios. Four equal resistor
values or two pairs are available for the ACAS 0612 AT,
whereas the ACAS 0606 AT is available either with two equal
or two different resistor values. Find out more about Vishay’s

Resistance values to be selected from E24 and E96.
(2)
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 resistance 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 %.

Precision Thin Film Chip Resistor Array
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. These resistors do not feature a limited lifetime when operated within the permissible limits.

Vishay Beyschlag
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
2
O
3
) ceramic substrate
using a mask to separate the adjacent resistors and
conditioned to achieve the desired temperature coefficient.
Specially designed inner contacts are realized 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
(3)
.
Precision Thin Film Chip Resistor Array
Superior Moisture Resistivity
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
(3)
. 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
(1)
and the
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) and
Annex II (ELV II)
•
2002/95/EC Restriction of
Substances directive (RoHS)
the
use
of
Hazardous
•
2002/96/EC Waste Electrical and Electronic Equipment
Directive (WEEE)
APPROVALS
The chip resistor array is
AEC-Q200
qualified.
Where applicable, the resistors are tested in accordance with
EN 140401-801
which refers to
EN 60115-1
and
EN 140400.
