ACAC 0612, ACAS 0612 - Precision
Vishay Beyschlag
Precision Thin Film Chip Resistor Array
FEATURES
• Advanced thin film technology
• Two pairs or four equal resistor values
• TCR tracking down to 10 ppm/K (± 5 ppm/K)
• Tolerance matching down to 0.1 % (± 0.05 %)
• Pure Sn termination on Ni barrier layer
ACAC 0612 (concave terminations) and ACAS 0612 (convex
terminations) thin film chip resistor arrays combine the
proven reliability of precision thin film chip resistor products
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. A small
package enables the design of high density circuits in
combination with reduction of assembly costs. Four equal
resistor values or two pairs are available.
• Compliant to RoHS directive 2002/95/EC
APPLICATIONS
• Precision analogue circuits
• Voltage divider
• Feedback circuits
• Signal conditioning

Notes
(1) 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 %.
