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 Compliant to RoHS directive 2002/95/EC 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 APPLICATIONS tolerance matching and TCR tracking make this product Precision analogue circuits perfectly suited for applications with outstanding 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. Four equal resistor values or two pairs are available.

Furthermore, in order to achieve the same tolerance of 0.05 % of individual resistors, an array requires a matching of 0.1 %.

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.
