Precision Thin Film Chip Resistor Array
FEATURES
• Advanced thin film technology
• Two pairs or four equal resistor values
• Relative TCR down to ± 5 ppm/K (tracking)
• Relative tolerance down to ± 0.05 % (matching)
• Pure Sn termination on Ni barrier layer
The ACAS 0612 thin film chip resistor arrays combine the
proven reliability of precision thin film chip resistor products
with the advantages of chip resistor arrays. Defined relative
tolerance (matching) and relative TCR (tracking) make this
product perfectly suited for applications with outstanding
requirements towards stable fixed resistor ratios. A small
package enables the design of high density circuits in
combination with reduction of assembly costs. The ACAS is
available with equal or different resistor values.

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.

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 % Al2O3) 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).
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 Life Vehicle Directive (ELV) and
Annex II (ELV II)
• 2011/65/EC Restriction of the use of Hazardous
Substances directive (RoHS)
• 2002/96/EC Waste Electrical and Electronic Equipment
Directive (WEEE)
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
TESTS
Where applicable, the resistors are tested in accordance
with EN 140401-801 which refers to EN 60115-1 and
EN 140400.
