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
