ACAS 0612 - Precision www.vishay.com Vishay Beyschlag 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 Material categorization: For definitions of compliance The ACAS 0612 thin film chip resistor arrays combine the please see www.vishay.com/doc 99912 proven reliability of precision thin film chip resistor products with the advantages of chip resistor arrays. Defined relative APPLICATIONS tolerance (matching) and relative TCR (tracking) make this product perfectly suited for applications with outstanding Precision analogue circuits requirements towards stable fixed resistor ratios. A small Voltage divider package enables the design of high density circuits in Feedback circuits combination with reduction of assembly costs. The ACAS is Signal conditioning available with equal or different resistor values.
