Precision Thin Film Chip Resistor Array

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.

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

• Material categorization: For definitions of compliance

please see www.vishay.com/doc?99912

APPLICATIONS

• Precision analogue circuits

• Voltage divider

• Feedback circuits

• Signal conditioning

Notes

• The relative figures of tolerance, TCR and drift are related to a medial axis between the maximum and minimum permissable deviation of

the resistor array. For detailed information please refer to the application note: Increasing Accuracy in Feedback Circuits and Voltage

Dividers with Thin Film Chip Resistor Arrays (www.vishay.com/doc?28194).
