Vishay's ACAS 0612 resistor arrays are suitable for use in voltage dividers, feedback circuits, and signal conditioning functions. The ACAS 0612 precision series resistor arrays feature absolute TCR of ±25ppm/K and tracking TCR of 15ppm/K (equivalent to ±7.5ppm/K), with tracking TCR of 10ppm/K available upon request. The ACAS 0612 precision series arrays have absolute tolerance of ±0.25% and matched tolerance of 0.1% (equivalent to ±0.05ppm/K), while the ACAS 0612 professional series arrays have absolute tolerance of ±1%.
The resistor arrays have a footprint of 1.6mm x 3.2mm, a reduction of approximately 40% when compared to the use of four discrete 0603 resistors. Resistance options range from 100Ω to 221KΩ, and arrays are available with four equal values, four different values, or two equal value pairs. Maximum power dissipation for the new arrays is 0.3W, with individual resistors rated at a maximum of 0.1W.
For arrays featuring differing individual resistance values the Rmin/Rmax ratio is 1:10 for the professional series arrays and 1:5 for the precision series arrays. Close tolerance matching of 0.1% in the case of the precision series arrays ensures highly reliable and stable fixed resistor ratios.
